Stoichiometric, low stress, silicon rich, LPCVD Silicon Nitride standard and custom processes are available for 1in, 2in, 3in, 4inch, 5in, 6in, 8in and 12 in wafers [25mm, 50mm,75mm,100mm, 125mm,150mm, 200mm and 300mm wafers]. Low pressure chemical vapor deposition of Silicon Nitride processes are available for device grade silicon wafers, fused silica wafers, silicon carbide, sapphire and SOI wafers, delivered in sealed containers, precleaned by customers. This is a high temperature process and wafers should be free of any photoresist or organic contamination. HTE Labs acceptance of customer supplied wafers is conditional, pending customer full disclosure of substrate composition, layer by layer, last process step or last cleaning process. For wafers supplied by HTE Labs, a standard chemical cleaning process may include RCA Clean as well as HF Dip.
