摘要:
A method of forming borderless contacts and a borderless contact structure for semiconductor devices. A preferred embodiment comprises using a second etch selectivity material disposed over a first etch selectivity material to preserve the first etch selectivity material during the etch processes for the various material layers of the semiconductor device while forming the borderless contacts.
