    • A wafer carrier adapted to hold a plurality of wafers and is positioned on an elevator plate in a load lock. The elevator plate is adapted to move between a first position with the carrier in a first chamber of the load lock and a second position with the carrier in the auxiliary chamber. In the second position, the elevator plate substantially seals the auxiliary chamber from the first chamber. In use, a first wafer is placed onto the wafer carrier. The wafer carrier can moved into the auxiliary chamber before or after the first wafer is placed onto the wafer carrier. The first wafer is auxiliary processed in the auxiliary chamber. A second wafer is placed onto the wafer carrier. Preferably after the second wafer is placed onto the wafer carrier, the first wafer is removed from the load lock. A third wafer is preferably then placed onto the wafer carrier so that the second wafer can cool. The second wafer is then removed from the load lock. The cycle is repeated.
    • 适于保持多个晶片并且位于加载锁中的电梯板上的晶片载体。 所述升降板适于在所述负载锁的第一室中的所述载体的第一位置和所述辅助室中的所述载体的第二位置之间移动。 在第二位置,升降板基本上将辅助室与第一室密封。 在使用中,将第一晶片放置在晶片载体上。 在将第一晶片放置在晶片载体上之前或之后,晶片载体可以移动到辅助室中。 第一个晶片在辅助室中辅助处理。 将第二晶片放置在晶片载体上。 优选地,在将第二晶片放置在晶片载体上之后,将第一晶片从负载锁上移除。 然后优选将第三晶片放置在晶片载体上,使得第二晶片可以冷却。 然后将第二个晶片从负载锁中取出。 重复循环。
