Overview

The SS-4 is a stand-alone wafer scrubber system developed by TEL. It is based on the Clean Track Mark 7 photoresist processing system and utilizes the Mark 7’s non-vacuum wafer handling capability. With TEL’s unique brushes and mechanical chuck, the SS-4 is capable of cleaning both sides of the wafer on a carrier-to-carrier basis, contributing remarkably to enhancing the megabit process yield. The SS-4 also offers the option to expand the variety of cleaning processes by combining the brush with a jet or Megasonic cleaning dispenser. Additionally, the SS-4 features TEL’s newest cleaning head, the hydraulic membrane head, which can be used with patterned, hydrophobic surfaces and even soft metal layers, expanding the applications for which scrubbers can be used.
