To support our comprehensive line of PVD thin film deposition materials, Materion works closely with customers to provide PVD consumables to support the sputtering process and to help produce uniform coatings. Our consumables include backing plates, crucible liners, and target bonding epoxies.
Backing Plates
Available in standard and custom designs to fit a range of targets, our backing plates:
- Are available in various materials including copper, copper alloys, aluminum and molybdenum
- Adhere well to the target
- Enhance the mechanical strength of the target
- Facilitate the cooling of the target and target assembly
- Permit good heat conduction
When choosing backing plate materials, the physical properties of the target and plate, and the expected operating temperatures must be considered. Backing tubes are also available, made of stainless steel or titanium.
Crucible Liners
Materion's crucible liners help improve thermal stability and reduce cycle times for electron beam evaporation processes. Available in a range of materials, our crucible liners enhance performance and are compatible with most manufacturers' evaporation sources. They also:
- Improve thermal stability
- Reduce heat transfer to the crucible
- Initiate higher evaporation rates
- Enable quick material changes to minimize chamber downtime
- Reduce power requirements
- Minimize crucible damage and maintenance
Target Bonding Epoxies
Silvertech PT-1: A two-part conductive silver-filled epoxy that replaces metallic bonding for high-temperature sputtering operations that creates better bonding for electronic and optoelectronic applications.
