摘要:
A method of semiconductor processing comprises providing a semiconductor wafer in a processing chamber; feeding at least one tungsten-containing precursor in a gas state into the processing chamber for atomic layer deposition (ALD) of tungsten; feeding at least one reducing chemical in a gas state into the processing chamber; and monitoring a concentration of at least one gaseous byproduct in the chamber; and providing a signal indicating concentration of the at least one gaseous byproduct in the chamber. The byproduct is produced by a reaction between the at least one tungsten-containing precursor and the at least one reducing chemical during the ALD.

A capacitive microphone and method for making the same are provided. A backplate with a plurality of holes is formed on a substrate with at least one cavity, and a diaphragm is formed above the backplate. There is an air gap between the backplate and the diaphragm. The air gap and the cavity communicate with each other by each hole. The diaphragm and the backplate are separated by a first distance and a second distance which is smaller than the first distance, such that the difference is formed on the diaphragm. The second distance area is fastened through surface stiction produced by mist or other fluids.
