  • Patent number: 6891169
    Abstract: An e-beam system generates a set of massively parallel beams of order of magnitude 1,000 by employing a flash eprom to store calibration data and to receive on/off signals directed through the address system of the memory array, the individual electron sources being mounted above the memory array in a geometric array that tracks the structure of the memory array.
    Type: Grant
    Filed: January 21, 2003
    Date of Patent: May 10, 2005
    Assignee: International Business Machines Corporation

  • Patent number: 6022766
    Abstract: An improved field effect transistor (FET) structure is disclosed. It comprises a first insulator layer containing at least one primary level stud extending through the layer; an undoped cap oxide layer disposed over the insulator layer and abutting the upper region of each stud; a primary level thin film transistor (TFT) disposed over the undoped cap oxide layer; and a planarized oxide layer disposed over the TFT. Multiple TFT's can be stacked vertically, and connected to other levels of studs and metal interconnection layers. Another embodiment of the invention includes the use of a protective interfacial cap over the surface of tungsten-type studs. The FET structure can serve as a component of a static random access memory (SRAM) cell. Related processes are also disclosed.

  • Patent number: 5665629
    Abstract: A SRAM cell with cross-coupled transistors, a pair of transfer gate transistors and a pair of load resistors is manufactured by forming a plurality of field effect transistors in a silicon substrate. In one embodiment, the transistors are formed in an SOI substrate to improve soft-error resistance. An insulator layer is deposited over the source, drain and gate contacts (device contact areas), hole openings are etched into the insulating layer to expose a plurality of device contact areas. A highly resistive layer is patterned to substantially cover and in contact with some selected contact hole openings and device contact areas. A conductive material is deposited into all of the contact hole openings so as to substantially over-fill the contact hole openings and make electrical contact with the device contacts and patterned resistive layer.
