Abstract The different steps in wafer fabrication such as photolithography‚ layer deposition and the machines and equipments used cause organic and inorganic particles to settle on the silicon wafer causing various defects in the semiconductor. Such defects can be minimized through wafer cleaning; RCA standard clean is a method generally used for this purpose. This technical report aims to discuss the chemical process of RCA cleaning and provide a qualitative analysis on the cleaning

techniques for cleaning silicon wafers before thermal treatments such as oxidation‚ after patterning by etching‚ after ion implantation‚ and before and after film deposition are therefore critically important because of the extreme sensitivity of the semiconductor surface and the nanometer sizes of the device features. As a consequence‚ the preparation of ultraclean in silicon wafers has become one of the key technologies in the fabrication of advanced ICs [1]. One may ask about the nature‚ types and origins

thin air‚ it was created after Bob Noyce and Gordon Moore first founded Fairchild Semiconductor with six other colleagues. Fairchild Semiconductor was going pretty well for about ten years when Bob and Gordon decided to resign because they were tired of not being able to do things the way they wanted to; they proceeded to establish a new integrated cicuits electronics company. Gordon suggested that semiconductor memory looked promising enough to risk starting a new company. Intel was born. Intel

The global Field-Programmable Gate Array (FPGA) market is expected to reach USD 9‚882.5 million by 2020‚ according to a new study by Grand View Research‚ Inc. Increasing demand for consumer electronics such as smartphones is expected to be the key driving force for the market over the next six years. Growing electronic content in automotives and penetration of Electric Vehicles (EV) and Hybrid Electric Vehicles (HEV) is also expected to drive the market over the forecast period. Miniaturization

few substitutes. Suppliers can affect an industry through its ability to raise prices or reduce the quality or purchased good and services. For the large semiconductor companies like Intel or AMD‚ suppliers have lack of selling power because semiconductor companies have hundreds of suppliers. Intel’s raw materials like silicon‚ semiconductors‚ and others can be purchased from a litany of manufacturers‚ thus affording the Intel a great deal of buyer power in selecting with whom to do business.

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
