摘要： Embodiments disclosed herein include a method of patterning a substrate. In an embodiment, the method comprises depositing a metal-oxo layer over a substrate, and applying a chemically amplified resist (CAR) over the metal-oxo layer. In an embodiment, the method further comprises exposing the CAR, and developing the CAR to form a pattern in the CAR. In an embodiment, the method further comprises transferring the pattern into the metal-oxo layer, and transferring the pattern into the substrate.

摘要： Embodiments disclosed herein include a method of patterning a substrate. In an embodiment, the method comprises, disposing a photoresist layer over a substrate, and exposing the photoresist layer to form an exposed region and an unexposed region in the photoresist layer. In an embodiment, the method further comprises treating either the exposed region or the unexposed region with a sequential infiltration synthesis (SIS) process to form a treated region, and developing the photoresist layer to remove portions of the photoresist layer other than the treated region.
