    Abstract: A plasma processing apparatus and method to control a temperature of a chamber component therein. A process chamber may include a temperature controlled chamber component and at least one remote heat transfer fluid loop comprising a first heat exchanger having a primary side in fluid communication with a heat sink or heat source, and a local heat transfer fluid loop placing the chamber component in fluid communication with a secondary side of the first heat exchanger. The local loop may be of significantly smaller fluid volume than the remote loop(s) and circulated to provide thermal load of uniform temperature. Temperature control of heat transfer fluid in the local loop and temperature control of the chamber component may be implemented with a cascaded control algorithm.

  • 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.
