摘要： Neutron detection cells and corresponding methods of detecting charged particles that make efficient use of silicon area are set forth. Three types of circuit cells/arrays are described: state latching circuits, glitch generating cells, and charge loss circuits. An array of these cells, used in conjunction with a neutron conversion film, increases the area that is sensitive to a strike by a charged particle over that of an array of SRAM cells. The result is a neutron detection cell that uses less power, costs less, and is more suitable for mass production.

摘要： The present invention provides silicon based thin-film structures that can be used to form high frequency optical modulators. Devices of the invention are formed as layered structures that have a thin-film dielectric layer, such as silicon dioxide, sandwiched between silicon layers. The silicon layers have high free carrier mobility. In one aspect of the invention a high mobility silicon layer can be provided by crystallizing an amorphous silicon layer. In another aspect of the invention, a high mobility silicon layer can be provided by using selective epitaxial growth and extended lateral overgrowth thereof.

摘要： A contact of large dimensions having a stringer strongly adhered to a contact hole's sidewalls. The contact hole is made to have a patterned perimeter having grooves protruding outward. The grooves have a size equal to a minimum contact dimension in at least one direction so as to ensure good step coverage into the groove areas. The grooves serve to anchor the stringer to the contact hole sidewalls by increasing the sidewall's surface area which increases adhesion, distributing stress from the stringer to the groove areas, and providing grooves with good step coverage.

摘要： A method of increasing the radiation hardness of a semiconductor device using a modified high density plasma oxide (MHDPDX) film is described. In the method a high density plasma (HDP) process is used to deposit the MHDPDX film. During the HDP process, the silicon source gas to oxygen source gas ratio is chosen so as to deposit an excess silicon content within the MHDPDX film. The MHDPDX film is then annealed to cause the excess silicon to migrate and amalgamate, creating silicon nanoclusters having an average size of about 3-5 nm. The rad-hard properties of conventional BPSG films and various MHDPDX films are then compared.

摘要： An apparatus and method for integrating a submicron CMOS device and a non-volatile memory, wherein a thermal oxide layer is formed over a semiconductor substrate and a two layered polysilicon non-volatile memory device formed thereon. A portion of the thermal oxide is removed by etching, a thin gate oxide and a third layer of polysilicon having a submicron depth is deposited onto the etched region. The layer of polysilicon is used as the gate for the submicron CMOS device. In so doing a submicron CMOS device may be formed without subjecting the device to the significant re-oxidation required in formation processes for dual poly non-volatile memory devices such as EPROMs and EEPROMs, and separate device optimization is achieved.

摘要： An EEPROM transistor fabricated with a single polysilicon layer. An MOS transistor is fabricated with a subsurface electrode region defined by a stripe in a first direction. A layer of thin oxide is arranged in a second stripe, perpendicular to the first stripe and a polysilicon layer, arranged in a third stripe is disposed over the second stripe of thin oxide. An adjoining parallel plate capacitor is formed by a subsurface region of the same conductivity type as the subsurface electrodes in the first stripe. An insulative second plate of thin oxide is joined to the second stripe and a third plate of the capacitor is formed by a polysilicon plate over the oxide plate. Vertical metallization stripes in the first direction may contact with some components, while parallel metal stripes in a second layer in a perpendicular direction may contact with the remaining members. The stripe geometry allows lateral and vertical four-way symmetry for implementation of a large number of memory storage cells on a chip or wafer.
