Semiconductor
Custom Welded Bellows for Optics, Display, WFE and more
THE MARKET TREND
As the Semiconductor Process Equipment Market enters its 4th decade, Moore’s Law continues to be a signpost on the trends toward smaller feature size, larger wafers and the faster process speeds in this industry.
This has accelerated the needs for cleanliness, increased precision and the need for higher reliability and life in all components. This also applies to related processes in Flat Panel Display and Solar Panel fabrication. The worldwide market growth in these industries had made supply chain support an increasing concern.
WHERE ARE KSM Edge Welded Metal Bellows USED?
KSM is a key strategic supplier to most of the largest equipment OEMs, worldwide.
KSM custom bellows are used at almost every step from Silicon Crystal Ingot Growth thru Front End [Ion Implant, Etch, PVD/MCVD, Lithography, ALD and CVD] to Back End [Wafer Slicing, Inspection and Packaging].
APPLICATIONS INCLUDE:
- Crucible Lifts [Flexible Gas Lines, Robot Drive Couplings]
- Cassette Lifts [Heater Lift Bellows, Rotatable Beamlines]
- Chamber Connectors [Load Locks, Sputter Sources]
- Chamber Door Mechanisms [Pedestal Lifts, UHV Valve Seals]
- Chuck Holders [Pin Lifts, Vibration Dampeners]
- Drive Actuators [RF Transfer Connectors, Wafer Positioners]
- Heater / Pedestal / ESC and assemblies
