Abstract:
Shrinkage and mass losses are reduced in photoresist exposure and post exposure baking by utilizing a small group which will decompose. Alternatively a bulky group which will not decompose or a combination of the small group which will decompose along with the bulky group which will not decompose can be utilized. Additionally, polar functional groups may be utilized in order to reduce the diffusion of reactants through the photoresist.

Claim (Index 10):
A method comprising:\n forming a layer to be patterned over a metallization layer; depositing a photoresist on the layer to be patterned, the photoresist comprising a polymer resin, a photoactive compound, and a solvent, the polymer resin comprising:\n a hydrocarbon backbone; \n a bulky leaving group having more than nine carbon atoms and bonded to the hydrocarbon backbone; \n a bulky group which will not decompose bonded to the hydrocarbon backbone; and \n a small leaving group having less than nine carbon atoms, the small leaving group comprising a cycloalkyl group and one of a C 4 -C 5  alkyl group, an acetyl group, or an acetyl alkyl group, the small leaving group being bonded to the hydrocarbon backbone through the bulky group which will not decompose; \n exposing the photoresist to a patterned energy source to form an exposed region and an unexposed region, wherein the photoactive compound generates acids, bases, or free radicals in the exposed region, wherein the acids, the bases, or the free radicals cleave the bulky leaving group from the hydrocarbon backbone and cleave the small leaving group from the bulky group which will not decompose in the exposed region; and developing the photoresist to remove the photoresist from the exposed region or the unexposed region.
