Electrostatic Chucks

SEMCO E-CHUCKS is a product division of the SEMCO Group and has been operating since more than 25 years designing and manufacturing electrostatic chucks (ESC) and heating pedestals to the wafer processing industry. SEMCO E-CHUCKS provide leading OEMs, Semiconductor Fabs, foundries and laboratories worldwide with innovative and efficient wafer handling components as original equipment or retrofit. The company actively manages global support through SEMCO subsidiaries and service centers.

The SEMCO Electrostatic Chucks Division offers smart solutions for clamping and processing of thin and ultra-thin wafers based on its proprietary ESC capacitive technology. SEMCO E-CHUCKS may also provide cooling, heating, biasing, vacuum, rotating and tilting capabilities, and are used in most of the advanced semiconductor manufacturing processes, including lithography, ion-implantation, CVD, sputtering, etch, transport, metrology and inspection on any type of conductive and non-conductive substrate materials. Our ESC's are also available in multi polarities, are reworkable, and feature excellent thermal transfer properties under vacuum. It's no coincidence that SEMCO E-CHUCKS is today the preferred partner of most equipment manufacturers and refurbishers dealing with process or production challenges on a daily basis.
