In electronics, a wafer (also called a slice or substrate) is a thin slice of semiconductor, such as a crystalline silicon (c-Si), used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells. The wafer serves as the substrate for microelectronic devices built in and upon … See more In the semiconductor or silicon wafer industry, the term wafer appeared in the 1950s to describe a thin round slice of semiconductor material, typically germanium or silicon. Round shape comes from See more Challenges There is considerable resistance to the 450 mm transition despite the possible productivity … See more While silicon is the prevalent material for wafers used in the electronics industry, other compound III-V or II-VI materials have also been employed. See more • Die preparation • Epitaxial wafer • Epitaxy • Klaiber's law See more Formation Wafers are formed of highly pure, nearly defect-free single crystalline material, with a purity of 99.9999999% (9N) or higher.

A substrate with low resistivity equates to higher RF loss, negatively impacting RF performance. Si substrates also have a higher parasitic capacitance than SiC substrates, which results in Si substrates having a more limited operating bandwidth.

WebAn automated wafer handler is a robotics system designed to automate and facilitate the handling of silicon wafers during the semiconductor manufacturing process. Wafer handlers are integrated with semiconductor process tools which perform various manufacturing tasks throughout the semiconductor production lifecycle. WebThe first thing that you have to do is to check the specification of the wafer (attached to the wafer box) to identify the doping type/dopant (Boron doped (P-type) or Phosphorus doped...
