Etch processes designed for stepper resists

The stepper produces features down to 200 nm. Here, etch processes especially designed for stepper patterns and resists are described. We intend to develop them continuously so keep an eye on this page. The best ones so far are:

Process parameters

Time Pressure C4F8 SF6 O2 Coil Time Pressure C4F8 SF6 O2 Coil Platen HW Runs Keywords
