    摘要: A method of etching a silicon-containing layer 170 on a substrate 45 comprises the steps of placing the substrate 45 on a support 75 in a process chamber 50. The substrate 45 is exposed to an energized process gas comprising a bromine-containing gas, a chlorine-containing gas, an inorganic fluorinated gas, and an oxygen gas. The volumetric flow ratio of the gas constituents is selected so that the energized process gas etches regions 180a,b having different concentrations of dopant in the polysilicon layer 170 at substantially the same etching rate. Optionally, the gas composition is also tailored to simultaneously clean off etch residue from the internal surfaces of a process chamber 50 during etching of the substrate 45.

    摘要: A substrate processing method comprises providing a substrate 105 comprising etch resistant material 210 in a process zone 155, such as an energized gas zone in a process chamber 110. The etch resistant material 210 may comprise a resist material 230 over mask material 240. The process may further comprise removing the etch resistant material 210, such as the resist material 230, in the process zone 155 before etching underlying layers.

    摘要: A method for processing a silicon substrate disposed in a substrate process chamber includes transferring the substrate into the substrate process chamber. The substrate having a hard mask formed thereon and a patterned photoresist overlying the hard mask to expose portions of the hard mask. The chamber being the type having a source power system and a bias power system. The method further includes etching the exposed portions of the hard mask to expose portions of the silicon substrate underlying the hard mask. Thereafter, the patterned photoresist is exposed to a first plasma formed from a first process gas to remove the photoresist from the hard mask. Thereafter, the exposed silicon substrate is etched by exposing the substrate to a second plasma formed from a second process gas by applying RF energy from the source power system and biasing the plasma toward the substrate. The substrate is transferred out of the substrate processing chamber.

    摘要: A method for processing a substrate disposed in a substrate process chamber having a source power includes transferring the substrate into the substrate process chamber. A trench is etched on the substrate by exposing the substrate to a plasma formed from a first etchant gas by applying RF energy from the source power system and biasing the plasma toward the substrate. Byproducts adhering to inner surfaces of the substrate process chamber are removed by igniting a plasma formed from a second etchant gas including a halogen source in the substrate process chamber without applying bias power or applying minimal bias power. Thereafter, the substrate is removed from the chamber. At least 100 more substrates are processed with the etching-a-trench step and removing-etch-byproducts step before performing a dry clean or wet clean operation on the chamber.

    摘要: A slot machine with multiple payoff modes and award presentations. The payoff modes in one embodiment are associated with a basic game and include a first and second payoff mode, the second payoff mode defining a “SUPER SCATTER” feature. Game outcomes are selected in the first and second payoff mode and symbol groups associated with the game outcomes are evaluated in the first payoff mode for symbol combinations displayed relative to one or more paylines and in the second payoff mode for symbol combinations displayed in scatter-pay format. In one embodiment, the machine operates in the first payoff mode until the occurrence of a symbol combination triggering the second payoff mode, then operates in the second payoff mode for a single spin before returning to the first payoff mode. The award presentations include a non-linear sequence of award values which in one embodiment are associated with a bonus game characterized by characters bidding upon a selected object that may be presented in irregular time intervals. The sequence of award values (bids) including a first value (“opening bid”), a number of intermediate values (bids) and a final value (a “winning” bid). A payoff is awarded based on the final winning bid.

    摘要: An inductively-coupled plasma processing chamber has a chamber with a ceiling. A first and second antenna are placed adjacent to the ceiling. The first antenna is concentric to the second antenna. A plasma source power supply is coupled to the first and second antenna. The plasma source power supply generates a first RF power to the first antenna, and a second RF power to the second antenna. A substrate support disposed within the chamber. The size of the first antenna and a distance between the substrate support are such that the etch rate of the substrate on the substrate support is substantially uniform.
