Silicon wafer

Surface roughness

Semiconductors; Silicon wafer

Disruption of the planarity of the semiconductor surface;measured as a difference between highest and deepest surface features; can be as low as 0. 06nm or high quality Si wafers with epitaxial ...

Process related disruption of the crystallography order at the surface of single-crystal semiconductor substrates; typically caused by surface interactions with high energy ions during dry etching ...

Sputtering target

Semiconductors; Silicon wafer

Source material during sputter deposition processes;typically a disc inside the vacuum chamber which is exposed to bombarding ions,knocking source atoms loose and onto samples.

Poly

Semiconductors; Silicon wafer

Many (often) small single-crystal regions are randomly connected to form a solid; size of regions varies depending on the material and the method of its formation. Heavily-doped poly Si is commonly ...
