Pre-pattern surface modification for low-k dielectrics using A H2 plasma
Abstract:
A low-k dielectric layer (104) is treated with a dry H2 plasma pretreatment to improve patterning. Resist poisoning occurs due to an interaction between low-k films (104), such as OSG, and DUV resist (130). The H2 plasma pre-treatment is performed to either pretreat a low-k dielectric (104) before forming the pattern (130) or during a rework of the pattern (130).
