SEMICONDUCTOR MANUFACTURING APPARATUS WITH IMPROVED PRODUCTION YIELD
The present disclosure describes a semiconductor device manufacturing apparatus and a method for handling contamination in the semiconductor device manufacturing apparatus. The semiconductor device manufacturing apparatus can include a deposition apparatus and a processor. The deposition apparatus can include a chamber, a detection module configured to detect impurities in the chamber, and a gas scrubbing device configured to remove the impurities. The processor can be configured to receive, from the detection module, an impurity characteristic associated with the impurities; compare the impurity characteristic to a baseline characteristic; and instruct the gas scrubbing device to supply a decontamination gas in the chamber based on the comparison of the impurity characteristic to the baseline characteristic.
SORPTION CHAMBER WALLS FOR SEMICONDUCTOR EQUIPMENT
A sorption structure defined in a plasma process chamber includes an inner layer having one or more heating elements to heat the sorption structure, a middle section having a coolant flow delivery network through which a coolant circulates to cool the sorption structure to a temperature to allow selective adsorption of by-products released in the process chamber, and a vacuum flow network that is connected to a vacuum line to create low pressure vacuum and remove the by-products released from the sorption structure. A lattice structure is defined over the middle section, the lattice structure includes network of openings defined in a plurality of layers to increase surface area for improved by-products adsorption. The inner section is disposed adjacent to the middle section. An outer layer of the lattice structure faces an interior region of the chamber. The openings in the layers of the lattice structure progressively increase in size from the inner layer to the outer layer, such that the outer layer provides a larger surface area for adsorbing the by-products. The vacuum line is activated during adsorption step to create a low pressure region in the lattice structure relative to a pressure in the chamber so as to adsorb the by-products. Desorption step is performed in conjunction with WAC/CWAC to reliably remove the accumulated by-products from the sorption wall.
