    摘要: Fuses for integrated circuits and semiconductor devices, methods for making and using the same, and semiconductor devices containing the same. The semiconductor fuse contains two conductive layers, an overlying and underlying layer, on an insulating substrate. The underlying layer comprises titanium nitride and the overlying layer comprises tungsten silicide. The semiconductor fuse may be fabricated during manufacture of a local interconnect structure containing the same materials. The fuse, which may be used to program redundant circuitry, is blown by electrical current rather than laser beams, thus allowing the fuse width to be smaller than prior art fuses blown by laser beams. The fuse may also be blown by less electrical current than the current required to blow conventional polysilicon fuses having similar dimensions.

    摘要: Methods for making surface channel MOS transistors. The methods are practiced by providing a substrate with at least one isolation region, forming a first dielectric layer over the substrate, forming a first polysilicon layer over the first dielectric layer, removing a portion of the first polysilicon layer to expose a portion of the first dielectric layer, forming at least one diffusion region in the substrate underlying the exposed portion of the first dielectric layer, removing the exposed portion of the first dielectric layer, forming a second dielectric layer over the first polysilicon layer and the at least one diffusion region, forming a second polysilicon layer over the second dielectric layer, removing the portion of the second dielectric layer and second polysilicon layer overlying the first polysilicon layer, depositing a conductive layer over the first and second polysilicon layers, depositing a third dielectric layer over the conductive layers and removing a portion of the third dielectric layer, conductive layer, first and second polysilicon layers, and first and second dielectric layers. The conductive layer may be tungsten silicide. These methods provide surface channel MOS transistors using fewer masking steps; flat polysilicon typography which allows fabrication of smaller device features; and tungsten silicide strapped gates scalable to less than 0.25 micrometers with a low resist level.

    摘要: According to the present invention, an ultrathin buried diffusion barrier layer (UBDBL) is formed over all or part of the doped polysilicon layer of a polysilicide structure composed of the polycrystalline silicon film and an overlying film of a metal, metal silicide, or metal nitride. More specifically, according to one embodiment of the present invention, a memory cell is provided comprising a semiconductor substrate, a P well, an N well, an N type active region, a P type active region, an isolation region, a polysilicide gate electrode structure, and a diffusion barrier layer. The P well is formed in the semiconductor substrate. The N well is formed in the semiconductor substrate adjacent to the P well. The N type active region is defined in the P well and the P type active region is defined in the N well. The isolation region is arranged to isolate the N type active region from the P type active region. The polysilicide gate electrode structure is composed of a polycrystalline silicon film and an overlying metal, metal silicide, or metal nitride film. The polycrystalline silicon film comprises an N+ polysilicon layer formed with the N type active region and a P+ polysilicon layer formed with the P type active region. The diffusion barrier layer is formed in the polysilicide gate electrode structure over a substantial portion of the polycrystalline silicon film between the polycrystalline silicon film and the metal, metal silicide, or metal nitride film.
