Abstract: A method for automatically conducting a leak test for a vacuum system includes receiving a process status input representing the completion of a manufacturing cycle. On determining that the process status is in a complete state, the vacuum system isolation valve is closed. In one embodiment, the first pressure input is measured at the beginning of the leak test and compared to a second pressure input measured at the expiration of timer. If the difference between the first and second pressure measurements are greater than the configurable threshold pressure, then the vacuum system is determined to be leaky. In another embodiment, the vacuum system is determined to be leaky if at least one of a series of pressure measurements exceeds the threshold pressure value. In response to the determination of the leak, an interlock signal to disable the operation of the vacuum system is activated.

Abstract: An apparatus and a method for calibrating the position of a cassette indexer in a semiconductor process machine are described. The apparatus is constructed by a base plate, a top plate and at least two support members rigidly attaching the top plate to the base plate in a parallel relationship. On the bottom side of the top plate, is mounted at least two spaced-apart rows of distance sensors each having at least five sensors capable of sensing a distance in the cavity of the calibration apparatus. After a wafer blade is extended into the cavity of the apparatus, a sensor in the front row and a sensor in the back row can be used to sense a front-to-back tilt of the wafer blade, while two adjacent sensors in the same row can be used to sense a side-to-side tilt of the wafer blade.
