摘要： A method for cleaning a processing chamber that includes heating an inner surface of the processing chamber to a first temperature. The first temperature can be sufficient to cause a first species to become volatile. The first species can be one of several species deposited on the inner surface. A cleaning chemistry is injected into the processing chamber. The cleaning chemistry can be reactive with a second one of the species to convert the second species to the first species. The volatilized first species can also be output from the processing chamber. A system for cleaning the process chamber is also described.

摘要： 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.

摘要： A photoresist plasma pretreatment performed prior to a plasma oxide etch. The plasma pretreatment is performed with an argon plasma or a carbon tetrafluoride and trifluoromethane plasma with lower power than in the main etch or is performed with a plasma of difluoromethane or trifluoromethane and carbon monoxide but no argon diluent gas. Thereby, striations on the oxide wall are reduced.

摘要： A method of fabricating an interconnect structure comprising etching a via into an upper low K dielectric layer and into a hardened portion of a lower low K dielectric layer. The via is defined by a pattern formed in a photoresist layer. The photoresist layer is then stripped, and a trench that circumscribes the via as defined by a hard mask is etched into the upper low K dielectric layer and, simultaneously, the via that was etched into the hardened portion of the lower low K dielectric layer is further etched into the lower low K dielectric layer. The result is a low K dielectric dual damascene structure.

摘要： An arrangement for depositing a film at a bevel edge of a substrate in a plasma chamber. The arrangement includes a gas delivery system for supplying gas into the chamber. The arrangement also includes a pair of electrodes including a movable electrode and a stationary electrode, wherein the substrate is disposed on one of the pair of electrodes. The arrangement further includes a gap controller module configured for adjusting an electrode gap between the pair of electrodes to a gap distance configured to prevent plasma formation over a center portion of the substrate. The gap distance is also dimensioned such that a plasma-sustainable condition around the bevel edge of the substrate is formed. The arrangement moreover includes a heater disposed below the substrate and powered by an RE source, wherein the heater is maintained at a chuck temperature conducive for facilitating film deposition on the bevel edge of the substrate.

摘要： A method of cleaning a bevel edge of a semiconductor substrate is provided. A semiconductor substrate is placed on a substrate support in a reaction chamber of a plasma processing apparatus. The substrate has a dielectric layer overlying a top surface and a bevel edge of the substrate, the layer extending above and below an apex of the bevel edge. A process gas is introduced into the reaction chamber and energized into a plasma. The bevel edge is cleaned with the plasma so as to remove the layer below the apex without removing all of the layer above the apex.
