follow-up product to my silicon semiconductor would be to specialize in microelectronic packaging. My product would be used primarily in high reliability components that undergo complete testing and screening to Aerospace specifications. I would use source control drawings to further refine these standards to specific product processing specifications demanded by unique system designs. Microelectronic packaging is the custom packaging and encapsulation of a desired semiconductor or microcircuit in high

Semiconductors are either solid or liquid material‚ able to conduct electricity at room temperature more readily than an insulator‚ but less easily than a metal. Electrical conductivity‚ which is the ability to conduct electrical current under the application of a voltage‚ has one of the widest ranges of values of any physical property of matter. Such metals as copper‚ silver‚ and aluminum are excellent conductors‚ but such insulators as diamond and glass are very poor conductors. At low temperatures

Beyond Silicon Computing DNA Computers: Ever since scientists discovered that conventional silicon-based computers have an upper limit in terms of speed‚ they have been searching for alternate media with which to solve computational problems. That search has led us‚ among other places‚ to DNA. The advantage of DNA is that it is tiny‚ cheap‚ and can react faster than silicon. Since this fledgling field is only eight years old‚ it is difficult to guess at this stage what applications it may

Intrinsic Semi Conductors Intrinsic semiconductors are composed of only one kind of material. Silicon and germanium are two examples. They are also called "undoped semiconductors" or "i-type semiconductors". Extrinsic Semi Conductors Extrinsic semiconductors are made of intrinsic semiconductors that have had other substances added to them to alter their properties (they have been doped with another element). There are two types of extrinsic semiconductors: p-type (p for positive: a hole has

Photosynthesis and Semiconductor-Based Solar Cells Photosynthesis‚ by definition‚ is “the process by which green plants and certain other organisms transform light energy into chemical energy” (photosynthesis‚ 2011). This is a remarkable process that occurs naturally and is one that is required for all living organisms to sustain existence on this planet. The efficiency of this process has sparked inventions‚ such as the semiconductor-based solar cell‚ that would allow humans to produce energy

Silicon Element Silicon is a chemical element with the symbol Si and atomic number 14 and atomic mass is 28. It is a tetravalent metalloid‚ less reactive than its chemical analog carbon‚ the nonmetal directly above it in the periodic table‚ but more reactive than germanium‚ the metalloid directly below it in the table. Controversy about silicon’s character dates to its discovery; it was first prepared and characterized in pure form in 1823. In 1808‚ it was given the name silicium‚ with an -ium

What is Semiconductor A semiconductor is a solid whose electrical conductivity can be controlled over a wide range‚ either permanently or dynamically. Semiconductors are tremendously important technologically and economically. Silicon is the most commercially important semiconductor‚ though dozens of others are important as well. 1.2 What is Semiconductor Industry The semiconductor industry is the collection of business firms engaged in the design and fabrication of semiconductor devices

A study INTRODUCTION The semiconductor industry lives - and dies - by simple creed: smaller‚ faster and cheaper. The benefit of being tiny is pretty simple: finer lines mean more transistors can be packed onto the same chip. The more transistors on a chip‚ the faster it can do its work. Thanks in
