One of the most complex parts of this process is lithography: the step in which shapes are drawn onto a silicon wafer. There are several ways to do this, all of them rather complicated ...

Silicon wafers are a fundamental part of the semiconductor business. Every chipmaker needs to buy them in one size or another, such as 200mm, 300mm and others. Silicon wafer vendors produce and sell ...

Selective-area growth (SAG) combined with aspect-ratio trapping (ART) significantly reduces ... pumped GaAs-based lasers on standard 300 mm silicon wafers, entirely within a CMOS pilot ...

The chip starts out as a thin wafer of P-type silicon. This is then coated with a layer of silicon dioxide -- kind of a silicon rust, which doesn't conduct electricity. On top of this is placed a ...
