A semiconductor is a solid substance that has a conductivity between that of an insulator and that of most metals, either due to the addition of an impurity or because of temperature effects. Devices made of semiconductors, notably silicon, are essential components of most electronic circuits. Washington Mills’ abrasive powders, including aluminum oxide and silicon carbide, are used in wafer slicing, shaping and lapping.

Washington Mills’ powders are produced with reliable quality, controlling for contaminates internally and externally to the crystal structure ensuring customers a reliable, consistent process input. Washington Mills offers its customers tailored particle distributions and particle shape in efforts to maximize process efficiency and yield.
