Why Use Super Low Stress Nitride?

Silicon Nitride has good high temperature strength, creep resistance and oxidation resistance. Silicon Nitride's low thermal expansion coefficient gives good thermal shock resistance. Silicon Nitride is produced in three main types; Reaction Bonded Silicon Nitride (RBSN), Hot Pressed Silicon Nitride (HPSN) and Sintered Silicon Nitride (SSN). We have Silicon Nitride 2" - 12" all specs and quanities.

What are Super Low Stress Silicon Nitride Wafers?

Stoichiometric LPCVD Nitride  - Our Standard nitride film works great as hard mask for KOH etching and can be used as a tool for defining active regions during field oxidation.

Our Lotw Stress Niride retains all of the same benefits associated with our standard nitride but can also be used for Membranes, Cantilever Beams and other mechanical structures associated with MEMS devices.

Our Super low stress nitride has been developed for applications that require extremely low film stress. Film Stress can also be customized to meet your unique specifications.
