1. An article comprising:
a carrier comprising a carrier bonding surface having an underlying surface roughness;
a sheet comprising a sheet bonding surface having an underlying surface roughness; and
a surface modification layer disposed on at least one of the carrier bonding surface and the sheet bonding surface,
wherein the surface modification layer comprises a plasma polymerized material having of thickness of greater than 10 nm,
wherein the plasma polymerized material planarizes the at least one of the carrier bonding surface and the sheet bonding surface to produce a planarized surface roughness that is at least 1.2 nm less than the underlying surface roughness and less than 0.8 nm, and
wherein the carrier bonding surface and the sheet bonding surface are bonded with the surface modification layer so that the carrier is temporarily bonded to the sheet.
