摘要： A method for determining an endpoint for etching a layer includes steps of estimating the etch endpoint and, during etch, directing radiant energy at two or more wavelengths onto the layer to be etched, detecting the last intensity maximum reflected at a first wavelength prior to the estimated etch endpoint, and detecting the intensity maximum reflected at a second wavelength first occurring after the last intensity maximum at the first wavelength. Also, a method for determining an endpoint for etching a layer having an approximate initial thickness by steps of, during etch, directing radiant energy at three or more wavelengths onto the layer to be etched; selecting first, second, and third wavelengths; approximating an etch rate from the time interval between a first detected intensity minimum and an adjacent intensity maximum reflected at the third wavelength, estimating an etch endpoint from the approximate initial thickness of the layer and the approximate etch rate; detecting the last intensity maximum reflected at the first wavelength prior to the estimated etch endpoint; and detecting the intensity maximum reflected at the second wavelength first occurring after the last intensity maximum at the first wavelength. The material making up the layer is at least partly transparent to both the first and the second wavelength. The first wavelength is longer than both the second wavelength and the third wavelength. In some embodiments the third wavelength is longer than the second wavelength. The endpoint is at the point of intensity maximum of the second wavelength or is at a point following an interval thereafter.

摘要： A process chamber with a computer system that controls the process chamber is connected to one or more spectrometers. The spectrometers may be part of an interferometer or may be an optical emission spectrometer. The spectrometers may be CCD or photodiode arrays of 2,048 elements. An input board forms part of the computer system and is directly connected to the spectrometers. The input board provides data from the spectrometers to dual port memory, which is directly accessible to the CPU of the computer system. The use of a state machine and adder on the input board allows computation and placement of the data from the spectrometers on to the dual port memory, so that the CPU is not needed for such placement.

摘要： A process chamber with a computer system that controls the process chamber is connected to one or more sensors, which are used to monitor the process in the process chamber. The sensors are connected to the computer system in a client/server relationship, in a way that allows the sensors to be hot swappable plug and play sensors. The computer system exchanges various messages with the sensors, synchronizes with the sensors, and integrates and utilizes data sent from the sensors.

摘要： In a plasma processing system, a method for dynamically establishing a baseline is provided. The method includes processing a first substrate. The method also includes collecting a first signal data for the first substrate. The method further includes comparing the first signal data against the baseline. The method moreover includes including the first signal data in a recalculation of the baseline if the first signal data is within a confidence level range, which is in between a top level above the baseline and a bottom level below the baseline.
