摘要: A method and processing tool are provided for trimming a gate electrode structure containing a gate electrode layer with a first dimension. A reaction layer is formed through reaction with the gate electrode structure. The reaction layer is the selectively removed from the unreacted portion of the gate electrode structure by chemical etching, thereby forming a trimmed gate electrode structure with a second dimension that is smaller than the first dimension. The trimming process can be carried out under process conditions where formation of the reaction layer is substantially self-limiting. The trimming process can be repeated to further reduce the dimension of the gate electrode structure.

摘要: A method and system for trimming a feature on a substrate is described. During a chemical treatment of the substrate, the substrate is exposed to a gaseous chemistry, such as HF/NH3, under controlled conditions including surface temperature and gas pressure. An inert gas is also introduced, and the flow rate of the inert gas is selected in order to affect a target trim amount during the trimming of the feature.

摘要: A method for heating a substrate between a first process and a second process using a plasma is described. The heating method comprises thermally isolating the substrate on the substrate holder by removing the backside supply of a heat transfer gas and removing the clamping force. Furthermore, an inert gas, such as a Noble gas, is introduced to the plasma processing system and a plasma is ignited. The substrate is exposed to the inert plasma for a period of time sufficient to elevate the temperature of the substrate from a first temperature (i.e., typically less than 100° C.) to a second temperature (i.e., typically of order 400° C.).
