Abstract:
Provided are photoresist compositions useful in forming photolithographic patterns by a negative tone development process. Also provided are methods of forming photolithographic patterns by a negative tone development process and substrates coated with the photoresist compositions. The compositions, methods and coated substrates find particular applicability in the manufacture of semiconductor devices.
