  • Patent number: 6413802
    Abstract: A FinFET device is fabricated using conventional planar MOSFET technology. The device is fabricated in a silicon layer overlying an insulating layer (e.g., SIMOX) with the device extending from the insulating layer as a fin. Double gates are provided over the sides of the channel to provide enhanced drive current and effectively suppress short channel effects. A plurality of channels can be provided between a source and a drain for increased current capacity. In one embodiment two transistors can be stacked in a fin to provide a CMOS transistor pair having a shared gate.

  • Patent number: 5804504
    Abstract: A method for forming an upper metal wiring which is in contact with an under conductive layer in a highly integrated semiconductor device. The method includes the steps of forming a metal wiring layer on a lower insulating film, forming a contact hole in the insulating film to expose an under conductive layer, and growing a metal layer in the contact hole to fill up the contact hole, so that the metal wiring layer can be in contact with the lower conductive layer.

  • Patent number: 5783499
    Abstract: A structure of double level metal free of voids is fabricated by depositing an insulating layer on the planarized layer which results from the growth of selective oxide layers to the thickness of the first metal wirings in the presence of the photoresist film patterns that are used to form the first metal wirings on the lower oxide layer. In addition, a patterning step for a second metal layer deposited on the insulating layer can be carried out with ease by virtue of the planarized layer of the first metal wirings, giving rise to a significant increase in the production yield. Thus, it can be usefully applied for ultra large scale integration devices, which are under a design rule of less than 0.4 .mu.m.
