    摘要: Fabrication methods for bi-directional silicon controlled rectifier device structures. A well of a first conductivity type is formed in a device region, which may be defined from a device layer of a semiconductor-on-insulator substrate. An anode of a first silicon controlled rectifier is formed in the first well. A cathode of a second silicon controlled rectifier is formed in the first well. The anode of the first silicon controlled rectifier has the first conductivity type. The cathode of the second silicon controlled rectifier has a second conductivity type opposite to the first conductivity type.

    摘要: A semiconductor fabrication is described, wherein a MOS device and a MEMS device is fabricated simultaneously in the BEOL process. A silicon layer is deposited and etched to form a silicon film for a MOS device and a lower silicon sacrificial film for a MEMS device. A conductive layer is deposited atop the silicon layer and etched to form a metal gate and a first upper electrode. A dielectric layer is deposited atop the conductive layer and vias are formed in the dielectric layer. Another conductive layer is deposited atop the dielectric layer and etched to form a second upper electrode and three metal electrodes for the MOS device. Another silicon layer is deposited atop the other conductive layer and etched to form an upper silicon sacrificial film for the MEMS device. The upper and lower silicon sacrificial films are then removed via venting holes.

    摘要: Device structures with a reduced junction area in an SOI process, methods of making the device structures, and design structures for a lateral diode. The device structure includes one or more dielectric regions, such as STI regions, positioned in the device region and intersecting the p-n junction between an anode and cathode. The dielectric regions, which may be formed using shallow trench isolation techniques, function to reduce the width of a p-n junction with respect to the width area of the cathode at a location spaced laterally from the p-n junction and the anode. The width difference and presence of the dielectric regions creates an asymmetrical diode structure. The volume of the device region occupied by the dielectric regions is minimized to preserve the volume of the cathode and anode.
