The gate structure is disposed in the substrate, and the source region and drain regions being a first conductivity type respectively disposed at two sides of the gate structure. The doped region being a second conductivity type different from the first conductivity type is disposed below and separated from the gate structure, the source region, and drain region, the doped region.

摘要： A semiconductor device includes a semiconductor substrate, a fin-shaped structure, a gate structure, a first doped region, a second doped region, and an intermediate region. The fin-shaped structure is disposed on and extends upwards from a top surface of the semiconductor substrate in a vertical direction. The gate structure is disposed straddling a part of the fin-shaped structure. At least a part of the first doped region is disposed in the fin-shaped structure. The second doped region is disposed in the fin-shaped structure and disposed above the first doped region in the vertical direction. The intermediate region is disposed in the fin-shaped structure. The second doped region is separated from the first doped region by the intermediate region, and a bottom surface of the gate structure is lower than or coplanar with a top surface of the first doped region in the vertical direction.

摘要： A mask structure for a deposition device includes first segments and second segments. The first segments are arranged in a direction surrounding a central axis and separated from one another. The second segments are disposed above the first segments. Each of the second segments overlaps two of the first segments adjacent to each other in a vertical direction parallel to an extending direction of the central axis. A deposition device includes a process chamber, a stage, and the mask structure. The stage is at least partially disposed in the process chamber and includes a holding structure of a substrate. The mask structure is disposed in the process chamber, located over the stage, and covers a peripheral region of the substrate to be held on the stage. An operation method of the deposition device includes horizontally adjusting positions of the first segments and the second segments respectively between different deposition processes.

摘要： Some structures and methods to reduce power consumption in devices can be implemented largely by reusing existing bulk CMOS process flows and manufacturing technology, allowing the semiconductor industry as well as the broader electronics industry to avoid a costly and risky switch to alternative technologies. Some of the structures and methods relate to a Deeply Depleted Channel (DDC) design, allowing CMOS based devices to have a reduced σVT compared to conventional bulk CMOS and can allow the threshold voltage VT of FETs having dopants in the channel region to be set much more precisely. The DDC design also can have a strong body effect compared to conventional bulk CMOS transistors, which can allow for significant dynamic control of power consumption in DDC transistors. Additional structures, configurations, and methods presented herein can be used alone or in conjunction with the DDC to yield additional and different benefits.
