  • Patent number: 9208998
    Abstract: A tandem processing-zones chamber having plasma isolation and frequency isolation is provided. At least two RF frequencies are fed from the cathode for each processing zones, where one frequency is about ten times higher than the other, so as to provide decoupled reactive ion etch capability. The chamber body is ground all around and in-between the two processing zones. The use of frequency isolation enables feed of multiple RF frequencies from the cathode, without having crosstalk and beat. A plasma confinement ring is also used to prevent plasma crosstalk. A grounded common evacuation path is connected to a single vacuum pump.

  • Patent number: 8297225
    Abstract: A decoupled capacitive CVD reactor is described, which provides improved CVD capabilities, including processing at lower temperatures, performing alternating deposition and etching steps, and performing in situ cleaning of the chamber, without the need for a remote plasma source. Two RF frequencies are coupled to the susceptor, while the anode is grounded. The high frequency RF source is operated so as to control the plasma density, while the low frequency RF source is operated to control species bombardment on the substrate, so as to control the properties of the film being deposited. Additionally, both RF sources may be controlled, together with selection of gasses supplied to the chamber, to operate the chamber either in deposition mode, partial etch mode, etching mode, or cleaning mode.

  • Publication number: 20110030900
    Abstract: A plasma chamber having a switchable bias frequency superimposed onto plasma source frequency and applied to the cathode. A power supplier capable of generating multiple RF bias frequencies is coupled into a match network through a switch. The match network couples one of the bias frequencies to the cathode. Another match network applied a source RF power to the cathode. One parallel connection of variable shunt capacitor and fixed capacitor are provided between ground and input of the switch and another is connected between ground and the input of the source RF match network.

  • Publication number: 20100271745
    Abstract: An electrostatic chuck device in which the electrostatic chuck and support are made from high resistivity, high thermal conductivity and low RF energy loss dielectric materials is described. An advantage of this electrostatic chuck device is that the wafer surface electromagnetic field distribution is more uniform than conventional electrostatic chuck devices. As a result, the wafer etch rate, especially the wafer edge etch rate non-uniformity, is significantly improved compared with conventional electrostatic chuck devices.

  • Patent number: 7227244
    Abstract: A method of depositing and etching dielectric layers having low dielectric constants and etch rates that vary by at least 3:1 for formation of horizontal interconnects. The amount of carbon or hydrogen in the dielectric layer is varied by changes in deposition conditions to provide low k dielectric layers that can replace etch stop layers or conventional dielectric layers in damascene applications. A dual damascene structure having two or more dielectric layers with dielectric constants lower than about 4 can be deposited in a single reactor and then etched to form vertical and horizontal interconnects by varying the concentration of a carbon:oxygen gas such as carbon monoxide. The etch gases for forming vertical interconnects preferably comprises CO and a fluorocarbon, and CO is preferably excluded from etch gases for forming horizontal interconnects.
