Description

The Raith EBPG 5200 is a dedicated direct-write Electron Beam Pattern Generator that is used to pattern large areas by high-resolution electron beam lithography. This instrument has substrate holders to handle 3" wafers, piece parts from a couple of mm to 3" diameter and up to 6.35 mm thick, and 6" mask plates. This instrument can be outfitted with substrate holders to handle up to 200 mm wafers. While this instrument can be set to operate at 20, 50, or 100 keV, it is normally set for 100 keV operation (i.e. with an accelerating voltage of 100 kV, the average energy per electron is 100 keV).
