SiC Etch for Power & RF Devices | SPTS

Introduction. Etching SiC is a particularly challenging process since the material has a hardness approaching that of diamond. It also has a very stable chemical structure. SiC is more difficult to dry etch than some other compound layers e.g. GaAs, AlGaAs, InP, which can be etched in a conventional inductively coupled plasma (ICP) system.

Amorphous silicon (a-Si) is the non-crystalline form of silicon used for solar cells and thin-film transistors in LCDs.. Used as semiconductor material for a-Si solar cells, or thin-film silicon solar cells, it is deposited in thin films onto a variety of flexible substrates, such as glass, metal and plastic. Amorphous silicon cells generally feature low efficiency, but are one of the most

Tech Brief: A Look at Atomic Layer Deposition (ALD) | Lam

Atomic Layer Deposition. The secret to gaining improved control was to split the deposition process into half-reactions, each of which can be well-controlled. The ALD process starts by flooding the reaction chaer with a precursor that coats (or “adsorbs” onto) the exposed surface of the wafer. This process is called self-limiting because
