技术介绍
随着半导体工艺日益趋于精密化和生产力要求的不断膨胀,半导体制造设备的自动化要求也不断提高。半导体设备中硅片传输系统通常是利用传输机械手直接传送到硅片台,由硅片台承载硅片完成相关的半导体工艺。以用于完成光刻工艺的光刻设备为例,光刻设备中的硅片台直接从传输机械手接收硅片,然后硅片台承载硅片在基台上沿基台上设有的运动导轨移动,完成一系列的曝光动作,实现光罩图形到硅片的转移。 传统的硅片台的结构如图l所示,它包括用于承载硅片1的吸盘2,支撑腔3,气浮面4以及位于支撑腔3的真空接片手5。该真空接片手5具有三个可伸縮的真空管501。硅片台与传输机械手交接硅片时,真空接片手5的三个真空管501向上升起至预设高度,真空管501打开真空从而吸附硅片,从传输机械手中接过硅片,三个真空管501再缓慢下降直到硅片l被硅片台上的吸盘2吸住,将硅片l交接给硅片台的吸盘2。当硅片台承载硅片完成一系列的曝光后,硅片台内的真空接片手5的三个真空管501再度升起,利用真空吸附硅片并短暂支撑硅片 ...
