    摘要: Self-aligned semiconductor circuits and process for manufacturing the circuits in which a plurality of transistors (206, 208, 240; 206, 208, 242) is provided, the collector regions/contacts (240,228; 242, 228) and the base regions/contacts (254, 252; 256, 252) being mutually self-aligned. In one embodiment, the collectors have conductive layer contacts (such as metal) and are self-aligned to polysilicon base contacts while in another embodiment the base contacts are comprised of a conductive (metal) layer while polysilicon is used for the collector contacts. The collectors (240, 242) of these transistors can be butted to a recessed field oxide (214) to reduce the extrinsic base area and to minimize excess charge storage in the base region (208). The base contacts, whether polysilicon or metal, etc., provide alternate base current paths so that the removal of the extrinsic base area does not adversely affect the total amount of base current which can flow.

    摘要: A Dynamic Random Access Memory (DRAM) cell has a storage capacitor (3) disposed in a trench (5) formed in a semiconductor substrate (6). The substrate is heavily doped and forms the counterelectrode of the storage capacitor, and a heavily doped polycrystalline plug (4) disposed in the trench forms the other electrode. The DRAM cell includes an access transistor (8, 9, 10, 11) which is disposed adjacent the top of the storage capacitor, and source (8) of the access transistor is connected to the plug electrode (4).

    摘要: A vertical bipolar transistor structure has an extrinsic base region (4) covered by a metal silicide (eg WSi 2 ) layer (6) and a doped (eg with boron) polysilicon layer (7). The metal silicide and polysilicon layers (6, 7) have an opening therein with which the emitter (3) and intrinsic base region (2) of the transistor are aligned.
    The vertical bipolar transistor structure can be produced by a method including delimiting a transistor area in a semiconductor substrate, depositing in succession over the the transistor area a silicide layer (6), a doped polysilicon layer (7) and a silicon dioxide layer (8), forming an aperture through the silicon dioxide, the doped polysilicon and the silicide layers, forming an insulating layer (8A) over the transistor area and driving in dopant from the polysilicon layer to form an extrinsic base region (4), removing the insulating layer from the base of the aperture but not from the sidewall of the aperture and forming an intrinsic base region and an emitter aligned with the aperture and the extrinsic base region.

    摘要: A process for fabricating Ultra Large Scale Integrated (ULSI) circuits in Silicon On Insulator (SOI) technology in which the device structures, which can be bipolar, FET, or a combination, are formed in vertical silicon sidewalls having insulation under and in back thereof so as to create SKI device structures. The silicon sidewall device SOI structures, when fabricated, take the form of cells with each cell having a plurality of either bipolar devices, FET devices, or a combination of these devices, such as collectors, emitters, bases, sources, drains, and gates interconnected within the planes of the regions of the devices in the cells and can be interconnected within the planes of the regions of devices in adjacent cells. Further, the interconnections to adjacent cells can be made from the back of the silicon sidewalls.

    摘要: A vertical bipolar transistor structure has an extrinsic base region (4) covered by a metal silicide (eg WSi 2 ) layer (6) and a doped (eg with boron) polysilicon layer (7). The metal silicide and polysilicon layers (6, 7) have an opening therein with which the emitter (3) and intrinsic base region (2) of the transistor are aligned. The vertical bipolar transistor structure can be produced by a method including delimiting a transistor area in a semiconductor substrate, depositing in succession over the the transistor area a silicide layer (6), a doped polysilicon layer (7) and a silicon dioxide layer (8), forming an aperture through the silicon dioxide, the doped polysilicon and the silicide layers, forming an insulating layer (8A) over the transistor area and driving in dopant from the polysilicon layer to form an extrinsic base region (4), removing the insulating layer from the base of the aperture but not from the sidewall of the aperture and forming an intrinsic base region and an emitter aligned with the aperture and the extrinsic base region.
