  • Patent number: 6925006
    Abstract: A semiconductor device, such as a memory device or radiation detector, is disclosed, in which data storage cells are formed on a substrate. Each of the data storage cells includes a field effect transistor having a source, drain, and gate, and a body arranged between the source and drain for storing electrical charge generated in the body. The magnitude of the net electrical charge in the body can be adjusted by input signals applied to the transistor, and the adjustment of the net electrical charge by the input signals can be at least partially cancelled by applying electrical voltage signals between the gate and the drain and between the source and the drain.

  • Publication number: 20050156240
    Abstract: A method of forming a thin film transistor relative to a substrate includes, a) providing a thin film transistor layer of polycrystalline material on a substrate, the polycrystalline material comprising grain boundaries; b) providing a fluorine containing layer adjacent the polycrystalline thin film layer; c) annealing the fluorine containing layer at a temperature and for a time period which in combination are effective to drive fluorine from the fluorine containing layer into the polycrystalline thin film layer and incorporate fluorine within the grain boundaries to passivate said grain boundaries; and d) providing a transistor gate operatively adjacent the thin film transistor layer. The thin film transistor can be fabricated to be bottom gated or top gated. A buffering layer can be provided intermediate the thin film transistor layer and the fluorine containing layer, with the buffering layer being transmissive of fluorine from the fluorine containing layer during the annealing.

  • Publication number: 20050128851
    Abstract: A data storage device such as a DRAM memory having a plurality of data storage cells 10 is disclosed. Each data storage cell 10 has a physical parameter which varies with time and represents one of two binary logic states. A selection circuit 16, writing circuits 18 and a refreshing circuit 22 apply input signals to the data storage cells to reverse the variation of the physical parameter with time of at least those cells representing one of the binary logic states by causing a different variation in the physical parameter of cells in one of said states than in the other.

  • Publication number: 20050104107
    Abstract: An integrated circuit structure includes a digit line and an electrode adapted to be part of a storage cell capacitor and includes a barrier layer interposed between a conductive plug and an oxidation resistant layer. An insulative layer protects sidewalls of the barrier layer during deposition and anneal of a dielectric layer. The method includes forming the conductive plug recessed in an insulative layer. The barrier layer is formed in the recess and the top layer. An oxidation resistant conductive layer and a further oxide layer are formed in the recess. The conductive layer is planarized to expose the oxide or oxide/nitride layer. The oxide layers are then etched to expose the top surface and vertical portions of the conductive layer. A dielectric layer is formed to overlie the storage node electrode. A cell plate electrode is fabricated to overlie the dielectric layer.

  • Publication number: 20050063224
    Abstract: There are many inventions described and illustrated herein. In one aspect, the present invention is directed to a memory cell, architecture, and/or array and/or technique of writing or programming data into the memory cell (for example, a technique to write or program a logic low or State “0” in a memory cell employing an electrically floating body transistor. In this regard, the present invention programs a logic low or State “0” in the memory cell while the electrically floating body transistor is in the “OFF” state or substantially “OFF” state (for example, when the device has no (or practically no) channel and/or channel current between the source and drain). In this way, the memory cell may be programmed whereby there is little to no current/power consumption by the electrically floating body transistor and/or from memory array having a plurality of electrically floating body transistors.
