Abstract: A trench-gate transistor has an integral first layer of silicon dioxide extending from the upper surface of the semiconductor body over top corners of each cell array trench. The integral first layer also provides a thin gate dielectric insulating layer for a thick gate electrode and the integral first layer also provides a first part of a stack of materials which constitute a thick trench sidewall insulating layer for a thin field plate. Consistent with an example embodiment, there is a method of manufacture. A hardmask used to etch the trenches is removed before providing the silicon dioxide layer. The layer is then protected by successive selective etching of the oxide layer and the nitride layer in the upper parts of the trenches. After the gate electrodes are provided, layers for the channel accommodating regions and source regions may be formed through the oxide layer on the upper surface.

Abstract: There is provided a process for producing an SOI wafer in which, when producing an SOI wafer using Smart Cut technology, the surface can be smoothed after cleaving, the thickness of the SOI layer can be reduced, and the film thickness of the SOI wafer can be made uniform. In this process for producing an SOI wafer, hydrogen gas ions are implanted via an oxide film in a silicon wafer that is to be used for an active layer, so that an ion implanted layer is formed in the silicon bulk. Next, this active layer silicon wafer is bonded via an insulating film to a base wafer. By heating this base wafer, a portion thereof can be cleaved using the ion implanted layer as a boundary, thereby forming an SOI wafer. After the cleaving has been performed using the ion implanted layer as a boundary, the SOI wafer undergoes oxidization processing in an oxidizing atmosphere. This oxide film is then removed by, for example, HF solution.

Abstract: A carbon containing masking layer is patterned to include a plurality of container openings therein having minimum feature dimensions of less than or equal to 0.20 micron. The container openings respectively have at least three peripheral corner areas which are each rounded. The container forming layer is plasma etched through the masking layer openings. In one implementation, such plasma etching uses conditions effective to both a) etch the masking layer to modify shape of the masking layer openings by at least reducing degree of roundness of the at least three corners in the masking layer, and b) form container openings in the container forming layer of the modified shapes. Capacitors comprising container shapes are formed using the container openings in the container forming layer. Other implementations and aspects are disclosed.

A backside deposition for oxide insulation layer can be performed so that the oxide insulation layer can be located in the semiconductor base right under the inductive components for impeding the parasitic current loss generated by the inductive components in the semiconductor base due to electromagnetic induction. Therefore, performance of the inductive components operating in high frequency can be improved.

Abstract: A semiconductor integrated circuit is fabricated in a substrate having a semiconductor layer and an underlying insulator layer. The fabrication process includes a step of locally oxidizing the semiconductor layer to form a field oxide, during which step the semiconductor layer is protected by a nitride film. The nitride film has both openings to permit local oxidization in the integrated circuit area, and an opening defining an alignment mark adjacent to the circuit area. The alignment mark may be formed either in the semiconductor and insulator layers, or in a part of the nitride film left after the nitride film is removed from the circuit area. In either case, the edge height of the alignment mark is not limited by the thickness of the semiconductor layer. Using the nitride layer to define both the alignment mark and the field oxide reduces the necessary number of fabrication steps.
