Abstract:
A method for forming a field effect transistor device includes forming a first gate stack and a second gate stack on a substrate, depositing a first photoresist material over the second gate stack and a portion of the substrate, implanting ions in exposed regions of the substrate to define a first source region and a first drain region adjacent to the first gate stack, depositing a first protective layer over the first source region, the first gate stack, the first drain region, and the first photoresist material, removing portions of the first protective layer to expose the first photoresist material and to define a first spacer disposed on a portion of the first source region and a portion of the first drain region, removing the first photoresist material, and removing the first spacer.
