Abstract: A method of fabricating a complementary metal-oxide-semiconductor device is provided. The method includes forming a work function material layer segment on a gate dielectric layer over a first vertical fin and a bottom spacer layer on an n-type bottom source/drain adjoining the first vertical fin on a first region of a substrate, wherein the gate dielectric layer is also over a second vertical fin, bottom spacer layer on a p-type bottom source/drain adjoining the second vertical fin on a second region. The method further includes heat treating the work function material layer segment to produce a modified work function material layer segment on the first vertical fin with a shifted work function value, forming a second work function material layer on the modified work function material layer segment and the gate dielectric layer on the second vertical fin, and growing a top source/drain on each of the vertical fins.

Abstract: Microfluidic chips that can comprise thin substrates and/or a high density of vias are described herein. An apparatus comprises: a silicon device layer comprising a plurality of vias, the plurality of vias comprising greater than or equal to about 100 vias per square centimeter of a surface of the silicon device layer and less than or equal to about 100,000 vias per square centimeter of the surface of the silicon device layer, and the plurality of vias extending through the silicon device layer; and a sealing layer bonded to the silicon device layer, wherein the sealing layer has greater rigidity than the silicon device layer. In some embodiments, the silicon device layer has a thickness between about 7 micrometers and about 500 micrometers while a via of the plurality of vias has a diameter between about 5 micrometers and about 5 millimeters.

Abstract: As disclosed herein, a method is provided for simultaneously patterning features having a first width in a first portion such as a logic portion of an integrated circuit, and having a second width in a second portion such as an array portion of an integrated circuit. The method includes depositing a feature layer over a substrate and a hardmask material layer thereover. Photoresist patterns are then formed in the first and second portions with a critical dimension mask, and are then used to etch the hardmask material layer into hardmask patterns. Sidewall spacers are provided on sidewalls of the hardmask patterns in the second portion. Then, the feature layer is simultaneously etched in both first and second portions, using the hardmask patterns in the first portion to define features having a first width, and using the hardmask patterns and the sidewall spacers in the second portion to define features having a second width.
