摘要:
A double gate metal-oxide semiconductor field-effect transistor (MOSFET) includes a fin (220), a first gate (240) and a second gate (420). The first gate (240) is formed on top of the fin (220). The second gate (420) surrounds the fin (220) and the first gate (240). In another implementation, a triple gate MOSFET includes a fin (220), a first gate (710), a second gate (720), and a third gate (730). The first gate (710) is formed on top of the fin (220). The second gate (720) is formed adjacent the fin (220). The third gate (730) is formed adjacent the fin (220) and opposite the second gate (720).
摘要:
A method of manufacturing a MOSFET semiconductor device comprises forming a gate electrode (24) over a substrate (10) and a gate oxide (16) between the gate electrode (24) and the substrate (10); forming source/drain extensions (30, 32) in the substrate (10); forming first and second sidewall spacers (36, 38); implanting dopants (44) within the substrate (10) to form source/drain regions (40, 42) in the substrate (10) adjacent to the sidewalls spacers (36, 38); laser thermal annealing to activate the source/drain regions (40, 42); depositing a layer of nickel (46) over the source/drain regions (40, 42); and annealing to form a nickel silicide layer (46) disposed on the source/drain regions (40, 42). The source/drain extensions (30, 32) and sidewall spacers (36, 38) are adjacent to the gate electrode (24). The source/drain extensions (30, 32) can have a depth of about 5 to 30 nanometers, and the source/drain regions (40, 42) can have a depth of about 40 to 100 nanometers. The annealing is at temperatures from about 350 to 500 °C.

A method of manufacturing a semiconductor device (100) may include forming a fin structure (210) on an insulator (120). The fin structure (210) may include side surfaces and a top surface. The method may also include depositing a gate material (320) over the fin structure (210) and planarizing the deposited gate material (320). An antireflective coating (520) may be deposited on the planarized gate material (320), and a gate structure (510) may be formed out of the planarized gate material (320) using the antireflective coating (520).

摘要:
A transistor structure (50) is provided comprising a source region (82, 86) having a N+ drain region (80) and a N' lightly doped drain region (80) and a N' lightly doped drain region (84). AP++ heavily doped (110) is provided. The P++ region (110) resides alongside at least a portion of at least one of the N- lightly doped source region (86) and N- lightly doped drain region (84). AP+ body region (120, 158) resides below a gate (90, 156) of the device (50) and between the source (82, 86) and drain (80, 84) regions. The P++ heavily doped region (110) provides a capacitive coupling between a body region (120, 158) and the gate (90, 156) of the device (50) and form a capacitive voltage divider with the junction capacitance of the device (50).
