Semitron® MPR1000 for the Semiconductor Industry

 
Semitron® MPR1000 is a new engineering material developed by Mitsuibishi Chemical Advanced Materials for semiconductor applications. MPR stands for maximum plasma resistance. It is intended for use in vacuum plasma chambers to replace ceramics and quartz for ICU production.  Ceramics are more expensive and quartz is prone to break. It also performs better in this application than PEEK, PAI such as Torlon® or polyimide thermoplastics.  For example MRP1000 has an increased life in plasma chambers of up to 25X in ozone than polyimides such as Vespel®. … Read more

Vented Plastic Screws in Vacuum Systems

Vented Screws
Plastic vented screws are often used in vacuum systems. They either have a hole drilled through their axis or along the side of the screw.  This hole allows the evacuation of trapped pockets of air and surface contaminates from blind-tapped holes. A bind-tapped hole is one that is drilled to a specified depth without breaking through the other side of the work piece. 
Vacuum Systems in HV, and UHV
Vented screws allow for faster and more efficient pump-down of High Vacuum (HV), … Read more
