Silicon and SOI Wafer

SOI wafers artificially form a layer of insulation between the surface and the layers to remove the effects from the layers to significantly enhance the machining, efficiency, and efficiency characteristics of the layer of high purity sealant formed on the insulating materials.

Conductive Metal Substrate

Conductive metal foil is an iron-chromium-nickel-based alloy steel containing molybdenum. This addition increases general corrosion resistance, improves resistance to pitting from chloride ion solutions, and provides increased strength at elevated temperatures. Corrosion resistance is improved, particularly against sulfuric, hydrochloric, acetic, formic and tartaric acids; acid sulfates and alkaline chlorides.
