    摘要: During a wafer process, fragments can break away from a wafer. The wafer fragments can compromise the accuracy of the temperature signals generated by sensor probes in a rapid thermal process. In particular, the fragments can attenuate or otherwise interfere with the radiation received from the wafer. This interference can undermine the accuracy of the temperature measurement signal generated by the probes. If the temperature control function is compromised, excessive temperature gradients can result in damage to the wafer, reducing device yield and degrading device quality. To alleviate the effects of wafer fragments, the presence of a wafer fragment is detected. An image acquisition device acquires an image of an area adjacent the sensor probe. A processor analyzes the acquired image to determine whether a wafer fragment is present. One approach involves comparing the acquired image to a reference image taken in the absence of a wafer fragment quantifying the amount of deviation. Another approach involves analyzing the acquired image for optical density contrast changes indicative of the presence of a wafer fragment. Detection of a wafer fragment allows the rapid thermal process to be stopped so that the fragment can be cleared away, either manually or automatically, prior to insertion of the next wafer into the chamber.

    摘要: An apparatus for purging a space in a processing chamber comprises a source of a purge gas; an inlet portion of a purge ring; an inlet baffle located in the inlet portion and fluidically connected to the source of purge gas; and an exhaust portion of the purge ring. The inlet portion and the exhaust portion define a ring hole space having a 360° periphery. The inlet baffle preferably surrounds not less than 180° of said periphery. The inlet baffle is operable to convey purge gas into the ring hole space. The exhaust portion is operable to convey purge gas and other matter out of the ring hole space. Cleaning of the purge ring and other structures in a processing chamber is conducted by flowing a cleaning gas through the inlet baffle. Some embodiments include a gas inlet plenum and an exhaust channel but not a purge ring.

    摘要: An apparatus for processing substrates includes a chamber, a substrate transfer element for transferring a substrate to and from the chamber, and a substrate support for receiving and holding a substrate within the chamber. The apparatus also includes multiple pins positioned and configured to be received by respective holes in the chamber bottom and moveable between a retracted position and an extended position. A pin actuation system is provided for moving the pins between the retracted position and the extended position. The pin actuation system controls the velocity at which the pins move and varies the speed of the pins by accelerating or decelerating at particular points during the pin cycle. A reduction in the cycle time is facilitated by accelerating the lift pins to relatively high speeds and then slowing the pins down prior to their arrival at locations where the substrate or wafer may be damaged. The throughput of the chamber can be increased, the likelihood of damage to the substrate can be reduced, and bouncing of the substrate while supported by the pins can be reduced.

    摘要: An apparatus and method for thermally processing a substrate employs lift pin for supporting or contacting the substrate while conveying radiation from the substrate to a detector and/or processor through a hollow member. The lift pin comprises a contact member flexibly mounted on the hollow member to adjust to the angle of the substrate. By conforming the orientation of the contact member to the angle of the substrate, accurate detection and processing of the substrate may be performed.
