Abstract:
1. A method for providing cooling with respect to at least one semiconductor device formed in a silicon substrate comprising the steps of: providing at least one diamond-filled trench adjacent to the at least one semiconductor device; and conducting heat from the at least one semiconductor device along the trench, wherein at least one semiconductor device comprises a transistor having a source region and a drain region formed in the silicon substrate and a gate formed at the top of the silicon substrate in contact with the source and drain regions and wherein said providing at least one diamond-filled trench adjacent to the at least one semiconductor device comprises the steps of: after fabrication of at least one gate at the substrate surface, one gate for each of said at least one transistor, depositing a blanket layer of diamond adjacent the at least one gate; patterning the blanket layer of diamond to obtain a patterned diamond layer having a plurality of diamond mask features and at least two patterned regions adjacent to said at least one gate; forming the source and drain regions of said at least one transistor through said at least two patterned regions; removing said plurality of diamond mask features from the substrate surface to form a plurality of mask feature openings; etching into said substrate in the plurality of mask feature openings to form a plurality of trenches; and filling the plurality of trenches with diamond; and further comprising forming a first diamond sidewall spacer at a first gate sidewall and in contact with the source region and forming a second sidewall spacer at the second gate sidewall and in contact with the drain region.
