What are Silicon Wafer Flats?
PAM XIAMEN offers Silicon Wafer Flats
Since Silicon Wafers look basically the same! Flats are cut into the edge of the wafers so users could determine the wafer’s dopant-type and orientation.

Silicon carbide has very stable characteristics, so that it can work stably in some harsh environments. Because of the stable chemical bonds, the technical threshold for silicon carbide production is very high. The growth conditions of silicon carbide crystal ingots are harsh, requiring high temperature (~2600℃) and high [...]

PAM-XIAMEN can offer 2” InGaAs/InP epi wafer for PIN as follows. InGaAs is the compound of InAs and GaAs. In the periodic table of chemical elements, In and Ga are elements of the third group, and As is the fifth group element. The properties of InGaAs [...]
Coulometric determination of arsenic in gallium arsenide crystal wafers
The determination of small variations in the stoichiometry of undoped, semi-insulating gallium arsenide can be achieved by using constant current coulometry. Samples taken from a wafer are etched in HF, dissolved in NaOH-peroxide solution, then treated [...]
