Abstract
A method of manufacturing an integrated circuit which reduces damage to the underlying base layer and the created oxide structures is disclosed herein. The method includes providing a hybrid stack disposed over an underlying layer, providing an IC structure pattern over the hybrid stack, selectively removing the top layer and a portion of the bottom layer according to the IC structure pattern, leaving a protective portion of the bottom layer according to the IC structure pattern, removing the protective portion of the bottom layer, building oxide structures in the underlying layer according to the IC structure pattern, and removing remaining portions of the hybrid stack. An integrated circuit is also disclosed which is prepared by a process including: providing a hybrid stack disposed over an underlying layer, providing an IC structure pattern over the hybrid stack, selectively removing a portion of the hybrid stack according to the IC structure pattern, leaving a protective portion of the bottom layer according to the IC structure pattern, building oxide structures on the underlying layer, and removing remaining portions of the hybrid stack.
