Abstract:
A method for fabricating a transistor gate with a conductive element that includes cobalt suicide includes use of a sacrificial material as a place-holder between sidewall spacers of the transistor gate until after high temperature processes, such as the fabrication of raised source and drain regions, have been completed. In addition, semiconductor devices (e.g., DRAM devices and NAND flash memory devices) with transistor gates that include cobalt suicide in their conductive elements are also disclosed, as are transistors with raised source and drain regions and cobalt suicide in the transistor gates thereof. Intermediate semiconductor device structures that include transistor gates with sacrificial material or a gap between upper portions of sidewall spacers are also disclosed.
Abstract:
A capacitor capable of functioning as a capacitor even when an AC voltage is applied thereto is provided without increasing the manufacturing steps of a semiconductor device. A transistor is used as a MOS capacitor where a pair of impurity regions formed on opposite sides of a channel formation region are each doped with impurities of different conductivity so as to be used as a source region or a drain region. Specifically, assuming that an impurity region that is doped with N-type impurities is referred to as an N-type region while an impurity region that is doped with P-type impurities is referred to as a P-type region, a transistor is provided where a channel formation region is interposed between the N-type region and the P-type region, which is used as a MOS capacitor.
Abstract:
A plurality of vertically oriented semiconductor devices (111, 112, 113) are physically separated from each other, and are not disposed within a same semiconductor body, or semiconductor substrate. The devices (111, 112, 113) may be added to a separately fabricated substrate (103) as a thin layer including several doped semiconductor regions which, subsequent to attachment, are etch to produce individual doped stacked structures. Alternatively the devices (111, 112, 113) may be fabricated prior to attachment to the substrate (103). The doped stacked structures my form the basis for diodes, capacitors and transistor devices, wherein stackable add-on layers may include interconnect lines (132).
Abstract:
The Vertical System Integration (VSI) invention herein is a method for integration of disparate electronic, optical and MEMS technologies into a single integrated circuit die or component and wherein the individual device layers used in the VSI fabrication processes are preferably previously fabricated components intended for generic multiple application use and not necessarily limited in its use to a specific application. The VSI method of integration lowers the cost difference between lower volume custom electronic products and high volume generic use electronic products by eliminating or reducing circuit design, layout, tooling and fabrication costs.
