Semiconductor Technology – Applications and Operations Behind Different Types

Semiconductors will not function if they do not possess electrical conductivity. The system takes place in the conductor’s connection with the insulator. This is perhaps the most basic among a list of assumptions behind semiconductor technology. But since this is very basic, there are yet other principles to take note of. In this regard, it pays to take a glimpse of the semiconductor types that are significant in some enterprises.

Semiconductors are very essential in technological advancements especially in mobile phone, computer, television and radio production. They are also highly crucial in production of transistors. In understanding more about semiconductor technology, it pays to take a look at its four types.

First kind of semiconductor – intrinsic

An intrinsic semiconductor is sometimes known as the purest of all semiconductor types. It contains thermal materials that have the ability of lessening covalent bonds as they freed electrons. Part of its work is to go to a solid mass for the support of electric component conductivity. In situations where the covalent bonds lose their electrons, electrical properties of the semiconductor will get affected.

Second kind of semiconductor – extrinsic

Aside from the intrinsic semiconductor there is also the extrinsic semiconductor. When compared to the intrinsic version, the semiconductor technology for extrinsic semiconductors rely upon doped or added particles. With this fact, it is also known as a doped semiconductor. The additional particles play a vital role in transforming the conductivity characteristics of the electrical component.

Here is one concrete sample for extrinsic semiconductors. Silicon, the most usual semiconductor, may be used in order to come up with a gadget. Each atom of silicon allocates four categories of valence electrons through a process known as covalent bonding. If silicon will be substituted by five valence electrons of phosphorous, four of the covalence electrons will be put together while the remaining one will be free.

Categories of extrinsic semiconductors – N-type and the P-type

Wrapping up the four classifications of semiconductors are the two sub-classes for extrinsic semiconductors. One is tagged as the N-type whereas the other is the P-type. The N-type is comprised of electrons and holes. The former plays as majority carriers while the second plays as minority carriers. This signifies that the electron’s concentrations are more than that of the holes.

As for the P-type semiconductor, it acts opposite functions with that of the N-type. To explain further, the P-type semiconductor technology contains holes that play as majority carriers while the electrons become minority role players. In some instances though, there are systems that follow a P-N Junction. This takes place when a P-type semiconductor is found at one side of the system even if the N-type was already made in the other side.

Android Developers – Developing a Cutting-Edge Android OS and Applications

Are you aware of the latest mobile phone developments? Technology evolves tremendously and you should chase every progress of it in order not to be left behind. The trend of technology innovations is moving too fast. That is why some people cannot be able to catch up with the latest updates about the best and newest products of technology. Whether we like it or not, we cannot stop or control the rapid pace of every development in technological applications and products. Today, we are living in the modern era and we need to embrace and adapt what technology has brought for us. The fastest development of technology is found in the advancement of mobile phones. Every year or even every 3 months, there are new models of phones released in the market. Currently, the latest mobile phones are smart phones and android phones. Smart phones and android developers are both determined to develop more enhancements most especially in the operating systems and software applications. However, android phones have more features and a stronger platform foundation. These are the factors that make the android phones turn out to be better than smart phones.

Android developers have developed an extensive and a cutting-edge application development. The objective of the development for the android operating system and applications is to provide users with a handy operational phone. There are so many dynamic features that can be used freely by the android users. Like the application framework that enables you to customise, change and reuse its components. The open development platform of android phones is providing the users with rich useful features. It is built with an open source operating system that is why you can possibly download or install any android or other apps because it can be recognised by the android’s OS and platform. The richness with the innovative applications in the android phones is worth the price. Most people prefer to buy mobile phones that can access almost all applications. Android phones are the most reliable mobile phone that can provide users’ demand. In fact, other phone manufacturers want to take advantage of android’s rapid and astounding development. Their objective is to make a good partnership with the android manufacturer because they know that they can’t compete with it in the market. Android phones’ acquisition creates remarkable impressions to the consumers and phone marketers as well.

Software application developers successfully provided solution to the compatibility issues to other mobile phones and in synchronizing apps mainly in gaming. There are three android operating systems that have been created magnificently by the professional developers. These are the Froyo, Gingerbread and ICS (Ice Cream Sandwich). These improve the interface of android phones to make it more advanced.

Data Arteries – Enabling Business Strategy Through Information Technology

Regardless of size and industry, every enterprise is dependent upon information technology, and must have a strategy for how to employ it, especially as the internet becomes more pervasive. Information technology strategy is an enabler of business strategy. Not only must an enterprise manage relationships with its constituencies, but it must be able to connect with them electronically through data arteries – information supply, value, and demand chains. The information supply and demand chains are external; the information value chains are internal.

An information technology strategy is a special case functional strategy because every function in the enterprise requires electronic information delivery capabilities, and many require electronic process control also. In very large enterprises, strategy may be formulated at both the enterprise and organizational unit levels.

As websites such as Facebook, LinkedIn, MySpace, Plaxo, and Twitter become more pervasive in business, linkages between application systems and databases and social networking websites will be more important to enable constituencies to communicate both collaboratively and cooperatively. Just as email has become a primary method of communication between enterprises and their constituencies, so will social networking sites especially for advertising and ecommerce.

Business intelligence information can be used to identify opportunities for competitive advantage. However, information technology itself can be an enabler of competitive advantage, especially when there are opportunities to digitize products or deliver information products electronically. In such cases, business strategy is inseparable from information technology strategy.

Information technology comprises the analytical and operational application systems, databases, and technical infrastructure (hardware and networks) of an enterprise. Not all computer technologies are information based. Computer technology is used for process control applications in special purpose equipment. However, connectivity is essential as applications become more integrated. As digital construction and manufacturing practices develop through such technologies as computer-aided design/computer-aided manufacturing (CAD/CAM), the processes, the control of processes, and the products and/or services delivered by processes all rely upon information technology for connectivity.

For example, in the manufacturing industry, not only can design and manufacturing work be conducted through integrated CAD/CAM processes with electronic linkages to carriers, such as FedEx and UPS, but the entire project and process management activities can be monitored electronically from ideation to product delivery.

Through technologies such as electronic data interchange and electronic funds transfer, data and both digital and information products flow through information supply and demand chains in parallel to material supply and product and/or service demand chains. Within the enterprise, data flows through information value chains from supply chains and to demand chains.

Developing an information technology strategy document is essential for describing the requirements and for educating users because:

  • The impact is enterprise or organizational unit wide and other elements of strategy cannot be implemented without it
  • Administrative activities, such as legal, finance, and human resources, and operational activities, such as research and development, procurement, manufacturing or equivalent, distribution, marketing, sales, and service depend on information technology – analytical and operational systems support both administrative and operational functions
  • The time frames, expenditures, risks, and magnitude of efforts are usually larger and more complicated than other initiatives and must be clearly understood; information technology projects have a tendency to go out of control and under deliver – therefore, contingency plans are always necessary
  • The subject matter can be complicated if not well explained

Information technology strategy is usually packaged as a separate but related document to the strategic plan. It is deployed and executed through specific programs and projects that develop new or enhance or maintain existing application systems, databases, and technical infrastructure.

Large information technology development projects are usually cross-functional, and may be part of a broader initiative sponsored by multiple functions collectively. Broader initiatives that have information technology components include:

  • Market research and development
  • Product research and development
  • Infrastructure research and development for processes and information delivery

For example – for the development of a:

  • Digital manufacturing system integrating both research and development and sales and production activities (sponsors: Manufacturing and Sales functions – impact is on Research and Development, Procurement, Manufacturing, Distribution, Sales, and Service functions)
  • Financial, managerial, and regulatory accounting and reporting system (sponsor: Finance function – impact is enterprise wide)
  • Human resource management system (sponsor: Human Resources function – impact is enterprise wide)
  • Sales tracking system (sponsor: Sales function – impact is on all salespeople enterprise wide)

Some projects can be solely for the Information Technology function, in which case it is a customer of itself.

Steering committees should be established for major programs and projects representing the various impacted functions in order to resolve cross-functional barriers. Major programs should come under the review of a planning and policy committee at the enterprise level.

Information technology strategy formulation is a project in its own right at the enterprise or organizational unit level. Very large projects are grouped as a program of inter-related components under a program manager. Projects can be stand alone also. A single project can deliver one or more application systems and related databases and technical infrastructure, or multiple projects may be required depending upon complexity.

For example, when launching a new product, it may be necessary to conduct marketing, product, and infrastructure development projects that include the delivery of new systems, and upgrades to existing systems. However, if an addition to the product line is launched at a later time, a new project or set of projects may be required to enhance or maintain the current systems, or even develop new ones.

The work breakdown structure for downstream development, enhancement, and maintenance projects decomposes into planning, analysis, design, construction, implementation, and performance measurement phases. The performance measurement phase can be conducted in parallel with the other phases, and each must end with a performance review. A feedback loop to future planning activities must be established so that lessons learned from the past can be reflected in future initiatives.

Meeting the cost and schedule requirements is always a major consideration. Hence, “meeting the date” is a frequent requirement for project success. However, after implementation, the scope of what was delivered and its quality is usually remembered more than when. In anticipation of the need to make changes after implementation, an adaption project may be necessary to tune, standardize, and integrate the deliverables.

The planning phase is conducted at the enterprise, organizational unit, or program levels for one or more projects depending upon size and complexity. However, each application system and related databases and technical infrastructure is delivered through a project with distinct analysis, design, construction, and implementation phases. Each phase always begins with a detailed planning activity to ensure that resources are allocated appropriately. The work breakdown structure does not preclude the use of iterative methodologies within each phase for rapid application development and prototyping. Development, enhancement, and maintenance of websites can be very rapid, and heavily interactive with user involvement, when the appropriate tools are used.

As enterprises become more dependent upon the internet for connectivity with constituencies, it is essential to develop, enhance, and maintain the information technology strategy on an ongoing basis. The strategy must emphasize connectivity through the data arteries as digital and information products become more pervasive.

Formulating information technology strategy is an enterpriship (entrepreneurship, leadership, and management) competency.
