Abstract:
A wafer transport assembly includes first and second wafer transport modules, and a buffer module coupled between the first and second wafer transport modules. The first and second wafer transport modules and the buffer module are aligned in a single directional axis. The buffer module includes a first buffer stack positioned at a first lateral end of the buffer module, and a second buffer stack positioned at a second lateral end of the buffer module. The first lateral end of the buffer module defines a first side protrusion nested between the first and second wafer transport modules and first and second process modules. The second lateral end of the buffer module defines a second side protrusion that is nested between the first and second wafer transport modules and third and fourth process modules. The first and second wafer transport modules and the buffer module define a continuous controlled environment.
Abstract:
Methods and systems for controlling processing state of a plasma reactor to initiate processing of production substrates and/or to determine a ready state of a reactor after the reactor has been cleaned and needs to be seasoned for subsequent production wafer processing are provided. The method initiate processing of a substrate in the plasma reactor using settings for tuning knobs of the plasma reactor that are approximated to achieve desired processing state values. A plurality of data streams are received from the plasma reactor during the processing of the substrate. The plurality of data streams are used to identify current processing state values. The method includes generating a compensation vector that identifies differences between the current processing state values and the desired processing state values. The generation of the compensation vector uses machine learning to improve and refile the identification and amount of compensation needed, as identified in the compensation vector. The method further includes transforming the compensation vector into adjustments to the settings for the tuning knobs and then applying the adjustment to the tuning knobs of the plasma reactor.
