    摘要: According to a semiconductor device of the present invention, a field oxide film is formed so as to cover the main surface of an SOI layer and to reach the main surface of a buried oxide film. As a result, a pMOS active region of the SOI and an nMOS active region of the SOI can be electrically isolated completely. Therefore, latchup can be prevented completely. As a result, it is possible to provide a semiconductor device using an SOI substrate which can implement high integration by eliminating reduction of the breakdown voltage between source and drain, which was a problem of a conventional SOI field effect transistor, as well as by efficiently disposing a body contact region, which hampers high integration, and a method of manufacturing the same.

    摘要: An upper insulating layer is formed on an upper surface of a gate electrode formed on an insulating substrate. A gate insulating layer is formed on sidewalls of the gate electrode and the surfaces of the upper insulating layer. A semiconductor layer is formed on the surfaces of the gate insulating layer. Three source/drain regions are formed in the semiconductor layer. Two independent channel regions are formed in the semiconductor layer along both side surfaces of the gate electrode. Source/drain regions are arranged on both ends of two channel regions. Each source/drain region has an LDD structure formed in a self alignment manner by an oblique ion implantation method and a vertical ion implantation method using sidewall insulating layers formed on the channel regions as masks.

    摘要: A stacked semiconductor device has three-dimensional alternate layers of iconductor elements and insulating layers each electrically insulating the adjacent upper and lower layers of semiconductor elements, formed on a single crystal semiconductor substrate. A semiconductor is deposited in openings formed respectively in the insulating layers to form single crystal semiconductor layers each having the same crystal axis as the single crystal semiconductor substrate respectively over the insulating layers, and semiconductor elements are formed respectively in a plurality of layers. The opening formed through the upper insulating layer reaches the lower layer of the semiconductor element immediately below the same upper insulating layer, and is formed at a position spaced apart horizontally from the opening formed through the lower insulating layer immediately below the same upper insulating layer. A semiconductor for forming the upper layer of a semiconductor having the same crystal axis as the lower layer of a semiconductor is deposited in the opening of the upper insulating layer so that satisfactory lateral epitaxial growth will occur over the insulating layer.

    摘要: A stacked static random access memory SRAM having a plurality of memory cells is disclosed. Individual memory cell has a portion formed in an upper active element layer in the device structure and a portion formed in a lower active element layer in the device structure separated from the upper layer by an intermediate insulating layer. A word line, a bit line and access transistors are formed in the same upper active element layer, eliminating the need for interconnecting them through the insulating layer. The elimination of the inter-layer connections helps to reduce the number of through-holes required to be made in the insulating layer. This in turn reduces the area to be occupied by the memory cell and leads to a simplified manufacturing process of the SRAM.
