    • PURPOSE: A closed valves for industrial and ultra clean applications. Semiconductor processing applications are examples of ultra clean applications CONSTITUTION: A genus of integrated valves having an integrated actuator with a thin, flexible membrane formed of silicon driven by pressure of a fluid trapped in a cavity formed by bonding a first and second die. The cavity has a resistor formed therein through which current is driven to cause the pressure to rise and the flexible membrane to flex. Movement of membrane is used to drive a valve element to a position where it unblocks a port to open the valve. This genus includes species such as ultra clean embodiments where a containment barrier keeps ultra clean processing gases confined to a wetted area having materials and bonding agents selected so as to be chemically compatible with the materials and conditions in the wetted area. Low leak species include a compliant material for a valve seat which is deformed by a ridge surrounding a port in the closed position. It is this port which is blocked and unblocked by movement of the valve element to close and open the valve.
    • 目的:用于工业和超清洁应用的封闭阀门。 半导体处理应用是超清洁应用的示例构成:具有集成致动器的集成致动器的集成致动器,其具有由通过粘合第一和第二管芯形成的空腔中的流体压力驱动的由硅形成的薄的柔性膜。 空腔具有形成在其中的电阻器,通过该电阻驱动电流以使压力升高并且柔性膜弯曲。 膜的移动用于将阀元件驱动到其阻止端口以打开阀的位置。 该属包括诸如超洁净实施例的物质,其中容纳屏障将超清洁处理气体限制在限定于湿润区域的物质和粘合剂中,所述材料和粘合剂选择为与化学兼容的润湿区域中的材料和条件。 低泄漏物质包括用于阀座的柔性材料,其通过围绕封闭位置的端口的脊变形。 这个端口被阀元件的移动阻塞和解锁,以关闭和打开阀门。
