    Abstract: Methods of facilitating gate height uniformity by controlling recessing of dielectric material and semiconductor devices formed from the methods are provided. The methods include, for instance, forming a transistor of the semiconductor device with an n-type transistor and a p-type transistor, the n-type transistor and the p-type transistor including plurality of sacrificial gate structures and protective masks at upper surfaces of the plurality of sacrificial gate structures; providing a dielectric material over and between the plurality of sacrificial gate structures; partially densifying the dielectric material to form a partially densified dielectric material; further densifying the partially densified dielectric material to create a modified dielectric material; and creating substantially planar surface on the modified dielectric material, to control dielectric material recess and gate height.

    Abstract: A method and apparatus are provided for automatically controlling the position of the spray bars and nozzles and the spray flow of a CMP in-situ cleaning module. Embodiments include fixing a wafer to a CMP cleaning module, the cleaning module having a first and a second group of spray bars and nozzles, the first and second groups of spray bars and nozzles being located proximate to opposite surfaces of the wafer; cleaning one or more of the surfaces of the wafer with a chemical spray forced through at least one of the groups of spray bars and nozzles; determining a measured profile of the one or more surfaces of the wafer; comparing the measured profile against a target profile; and adjusting automatically at least one of the first and second groups of spray bars and nozzles relative to the one or more surfaces of the wafer based on the comparison.
