TWO-STAGE BAKE PHOTORESIST WITH RELEASABLE QUENCHER

Last updated:

Abstract:

Two-stage bake photoresists with releasable quenchers for fabricating back end of line (BEOL) interconnects are described. In an example, a photolyzable composition includes an acid-deprotectable photoresist material having substantial transparency at a wavelength, a photo-acid-generating (PAG) component having substantial transparency at the wavelength, and a base-generating component having substantial absorptivity at the wavelength.
