  • Publication number: 20100126552
    Abstract: Methods and apparatus are provided for converting electromagnetic radiation, such as solar energy, into electric energy with increased efficiency when compared to conventional solar cells. A photovoltaic (PV) unit may have all electrical contacts positioned on the back side of the PV device to avoid shadowing and increase absorption of the photons impinging on the front side of the PV unit. Several PV units may be combined into PV banks, and an array of PV banks may be connected to form a PV module with thin strips of metal or conductive polymer formed at low temperature. Such innovations may allow for greater efficiency and flexibility in PV devices when compared to conventional solar cells.

  • Patent number: 6730600
    Abstract: A method for dry etching a material deposited on semiconductor device is performed by chemically reacting the material with an etchant gas. The etching process is conducted in a reaction chamber at a predetermined temperature and predetermined pressure within the reaction chamber and without the need of generating a plasma within the chamber or applying an electrical bias to the semiconductor device. A sufficient amount of gas is introduced into the reaction chamber to selectively remove the material from the semiconductor device.

  • Patent number: 6627963
    Abstract: The present invention provides a process for fabricating merged integrated circuits on a semiconductor wafer substrate. The process comprises forming a gate oxide on the semiconductor wafer substrate, forming a first transistor having a first gate on the gate oxide, and forming a second transistor having a second gate on the same gate oxide. The first transistor is optimized to a first operating voltage by varying a physical property of the first gate, varying a first tub doping profile, or varying a first source/drain doping profile. The second transistor is optimized to a second operating voltage by varying a physical property of the second gate, varying a second tub doping profile, or varying a second source/drain doping profile of the second transistor. These physical characteristics may be changed in any combination or singly to achieve the determined optimization of the operating voltage of any given transistor.

  • Patent number: 6602758
    Abstract: A method for forming single crystalline silicon-on-insulator (SOI) structures over a silicon substrate includes forming an amorphous silicon layer over an insulating layer and contacting the substrate through the insulating layer. An excimer laser having operating conditions and a wavelength chosen to selectively melt amorphous silicon irradiates the entire substrate surface and is largely non-absorbed by materials other than silicon when incident upon them. Heating of the substrate and other materials is therefore minimal. After a blanket radiation process selectively melts the amorphous silicon layer, cooling conditions are chosen such that a single crystal silicon film is formed during the solidification process due to contact to the single crystal silicon substrate which acts as a seed layer. Various devices may be formed on the SOI islands as well as on exposed portions of the substrate not covered by the SOI islands.

  • Patent number: 6593195
    Abstract: The memory element of the present invention utilizes a substrate, a first conductive connection, a second conductive connection, and an ionic layer. The substrate includes a source region, a drain region, and a channel region, which is disposed between the source region and the drain region. The ionic layer includes ions and is coupled to the substrate. The first connection is coupled to the source region, and the second connection is coupled to the drain region. An electrical field is applied through said ionic layer such that the ions in the ionic layer move. When the memory element is to exhibit a logical high state, the polarity of the electrical field causes the ions to move toward the channel region. This pulls the electrons in the source and drain regions into the channel region making the channel region conductive. When the memory element is to exhibit a logical low state, the polarity of the electrical field causes the ions to move away from the channel region.

  • Patent number: 6569690
    Abstract: Method for fabricating a structure. According to an exemplary embodiment, a structure is made by forming a layer of removable material with a first surface spaced a part from a second surface. The first surface is formed along a first region from which the material is removable. The first surface is altered by removal of material from the layer. Removed material from the first surface is monitored to detect fluctuations in a variable of composition in the layer, and removal of material from the first surface is terminated when the composition of monitored material meets a predetermined criterion. In an alternate embodiment a variable characteristic is imparted to a layer of material as a function of layer thickness and an operation is performed on the layer resulting in removal of material. Samples of removed material are monitored for variation in the characteristic and the operation is modified when a variation conforms with a criterion.
