Low Stress LPCVD Nitride with a Film Stress of less than 250 MPa Tensile is often used for building Membranes, Cantilever Beams and other mechanical structures. Low Stress Nitride is also very effective as a KOH . The characteristics of silicon-nitride films deposited with plasma-enhanced chemical vapor deposition (PECVD) can vary in composition and physical properties. An important parameter in the fabrication of micro-electro-mechanical systems (MEMS) devices is the control and tailoring of the film stress. In fact, silicon-nitride film stress can vary from tensile (up to 800 MPa) to compressive (-500 MPa), depending on the PECVD deposition conditions. Read more...

What's Cool About Micro-Electro-Mechanical Systems or MEMS For Short?

Well, if you're into tiny devices there is plenty. These tiny micro-devices may not be the buzz at your dinner table yet, but in years to come they are going to give us all something to talk about. Read more...

Physical Vapor Deposition Of Thin Film

Physical vapor deposition is a coating method where a thin film of material is deposited over the entire substrate at the same time. The main PVD methods are ion manipulation, laser surface alloying, plating and spluttering. PVD is a good coating process that can broadly be categorized under three phases namely emission from a source, condensation on substrates to be coated and transport in vacuum. Read more...
