  • Publication number: 20080044960
    Abstract: A process for conformally doping through the vertical and horizontal surfaces of a 3-dimensional vertical transistor in a semiconductor-on-insulator structure employs an RF oscillating torroidal plasma current to perform either conformal ion implantation, or conformal deposition of a dopant-containing film which can then be heated to drive the dopants into the transistor. Some embodiments employ both conformal ion implantation and conformal deposition of dopant containing films, and in those embodiments in which the dopant containing film is a pure dopant, the ion implantation and film deposition can be performed simultaneously.

  • Publication number: 20070212811
    Abstract: Device-enhancing coatings are deposited on CMOS devices by successively masking with photoresist each one of the sets of N-channel and P-channel devices while unmasking or leaving unmasked the other set, and after each step of successively masking one of the sets of devices, carrying out low temperature CVD steps with a toroidal RF plasma current while applying an RF plasma bias voltage. The temperature of the workpiece is held below a threshold photoresist removal temperature. The RF bias voltage is held at a level at which the coating is deposited with a first stress when the unmasked set consists of the P-channel devices and with a second stress when the unmasked set consists of N-channel devices.

  • Patent number: 7181927
    Abstract: A system for exchanging heat with primary coolant flowing through an intravascular catheter or externally-applied pad to warm or cool a patient. A secondary heat transfer element can be engaged with a primary heat transfer element and is not grounded when the primary heat transfer element is fully engaged with the secondary heat transfer element during operation. In contrast, the secondary heat transfer element is grounded when the primary heat transfer element is at a predetermined disengaged position relative to the secondary heat transfer element.

  • Publication number: 20060293732
    Abstract: A patient temperature control catheter or pad is warmed or cooled by coolant circulating through it. The coolant in turn is warmed or cooled as it flows through a cartridge that is placed against a control system TEC. For cooling, heat is removed from the TEC by tap water flowing through a reservoir that is in contact with the TEC. If desired, a small turbine can be disposed in the reservoir to be driven by the flowing tap water, and the turbine is coupled to a pump element that pumps the coolant through the catheter or pad.
