摘要： A multi-bridge-channel MOSFET (MBCFET) may be formed by forming a stacked structure on a substrate that includes channel layers and interchannel layers interposed between the channel layers. Trenches are formed by selectively etching the stacked structure. The trenches run across the stacked structure parallel to each other and separate a first stacked portion including channel patterns and interchannel patterns from second stacked portions including channel and interchannel layers remaining on both sides of the first stacked portion. First source and drain regions are grown using selective epitaxial growth. The first source and drain regions fill the trenches and connect to second source and drain regions defined by the second stacked portions. Marginal sections of the interchannel patterns of the first stacked portion are selectively exposed. Through tunnels are formed by selectively removing the interchannel patterns of the first stacked portion beginning with the exposed marginal sections. The through tunnels are surrounded by the first source and drain regions and the channel patterns. A gate is formed along with a gate dielectric layer, the gate filling the through tunnels and extending onto the first stacked portion.

摘要： A gate-all-around (GAA) transistor device has a pair of pillars that include the source/drain regions, a channel region bridging the source/drain regions, and a gate electrode and gate oxide which surround the channel region. The pillars are formed by providing a mono-crystalline silicon substrate, etching the substrate to form a pair of spaced-apart trenches such that a wall of the mono-crystalline silicon stands between the trenches, filling the trenches with insulative material, implanting impurities into the wall of mono-crystalline silicon, and forming an opening in the wall such that portions of the wall remain as pillars. A sacrificial layer is formed at the bottom of the opening. Then, the channel region is formed atop the sacrificial layer between the pillars. The sacrificial layer is subsequently removed and the gate oxide and gate electrode are formed around the channel region. One or more sidewall spacers are used to establish the effective width of the channel region and/or minimize parasitic capacitance between the source/drain regions and gate electrode.
