Abstract:
The present invention provides a method and a structure of increasing source and drain contact edge width in a two-dimensional material field effect transistor. The method includes patterning a two-dimensional material over an insulating substrate; depositing a gate dielectric over the two-dimensional material; depositing a top gate over the gate dielectric, wherein the top gate has a hard mask thereon; forming a sidewall spacer around the top gate; depositing an interlayer dielectric oxide over the sidewall spacer and the hard mask; removing the interlayer dielectric oxide adjacent to the sidewall spacer to form an open contact trench; depositing a copolymer coating in the contact trench region; annealing the copolymer to induce a directed self-assembly; performing a two-dimensional material etch over the two-dimensional material; removing the unetched copolymer without etching the gate dielectric; and etching the exposed gate in the source and the drain region to form a metal contact layer.

Claim (Index 18):
The method of increasing the source region and the drain region contact edge width in the two-dimensional material field effect transistor of  claim 16 , wherein the mesh template is made of polystyrene.
