Vacuum Systems in Semiconductor Fabrication Facilities
Methods and devices are provided wherein rotational gas-flow is generated by vortex generators to decontaminate dirty gas (e.g., gas contaminated by solid particles) in pumping lines of vacuum systems suitable for use at a semiconductor integrated circuit fabrication facility. The vacuum systems use filterless particle decontamination units wherein rotational gas-flow is applied to separate and trap solid particles from gas prior to the gas-flow entering a vacuum pump. Methods are also described whereby solid deposits along portions of pumping lines may be dislodged and removed and portions of pumping lines may be self-cleaning.
METHOD AND SYSTEM FOR RECOGNIZING AND ADDRESSING PLASMA DISCHARGE DURING SEMICONDUCTOR PROCESSES
A plasma discharge detection system detects undesirable plasma discharge events within a semiconductor process chamber. The plasma discharge detection system includes one or more cameras positioned around the semiconductor process chamber. The cameras capture images from within the semiconductor process chamber. The plasma discharge detection system includes a control system that receives the images from the cameras. The control system analyzes the images and detects plasma discharge within the semiconductor process chamber based on the images. The control system can adjust a semiconductor process in real time responsive to detecting the plasma discharge.
