Abstract
An improved apparatus and method for the manufacture of integrated circuits is disclosed. At least three protrusions extend from the wafer support susceptor. The protrusions slightly electrically decouple the wafer from the susceptor during plasma processing. The protrusions prevent gradual debris build-up on the susceptor from causing variation from lot-to-lot in plasma processing results.
