Abstract

A deposited Anti Reflective Coating (DARC) can react with an overlying photoresist. This problem is known as resist poisoning. A process described herein creates a blocking layer between the DARC and the photoresist. This blocking layer prevents the resist poisoning and does not affect the optical properties of the DARC.
