    • A Megasonic cleaning apparatus having at least one reflector (e.g., a parabolic or paraboloid reflector) positioned to collect otherwise wasted cleaning energy and redirect that energy to one or a plurality of positions on a wafer's edge is provided. A first embodiment comprises a complex parabolic reflector which has a width greater than that of the wafer and a preferred length approximately equal to the diameter of the wafer, and which is shaped to provide focal points which vary along the length of the parabolic reflector, such that energy striking the reflector at different points along the reflector's length is directed to a plurality of different points along the wafer's edge. A second embodiment comprises a simple parabolic reflector having a width greater than that of the wafer and a preferred length less than the diameter of the wafer, and which is provided to focus at a cord along the wafer's surface, effectively focusing cleaning energy on two points along the wafer's edge at any given time. Yet another embodiment of the invention comprises a paraboloid reflector having a width greater than that of the wafer and a preferred length which is substantially less than the diameter of the wafer and which is shaped to focus all collected energy to a single point on the wafer's edge. Multiple such reflectors may be positioned in the cleaning tank to optimize energy usage and wafer cleaning.

    • A chemical vapor deposition reactor has one or more deposition zones bounded by gas flow virtual walls, within a housing having closed walls. Each deposition zone supports chemical vapor deposition onto a substrate. Virtual walls formed of gas flows laterally surround the deposition zone, including a first gas flow of reactant gas from within the deposition zone and a second gas flow of non-reactant gas from a region laterally external to the deposition zone. The first and second gas flows are mutually pressure balanced to form the virtual walls. The virtual walls are formed by merging of gas flows at the boundary of each deposition zone. The housing has an exhaust valve to prevent pressure differences or pressure build up that would destabilize the virtual walls. Cross-contamination is reduced, between the deposition zones and the closed walls of the housing or an interior region of the housing outside the gas flow virtual walls.

    • A semiconductor substrate centering mechanism includes a plurality of substrate support pins, each pin having a top surface. The top surfaces of the pins define a plane in which the substrate is supported. Each pin has a tab mounted eccentrically at the top surface of the pin. The tabs extend upwardly relative to the top surfaces of the pins. The centering mechanism further includes a pin rotation mechanism adapted to rotate each pin. The pin rotation mechanism rotates the pins between a first position in which the tabs define an envelope that is larger than a circumference of the substrate and a second position in which the tabs define a centered position for the substrate. A telescoping arrangement of nesting shield segments may also be provided for each pin to prevent processing fluid from reaching a shaft of the pin. In one aspect the centering mechanism is coupled to a substrate support of a substrate processing location, and thus allows a substrate to be centered as it is lowered to the processing location.
    • 半导体基板定心机构包括多个基板支撑销,每个销具有顶面。 销的顶表面限定了其中衬底被支撑的平面。 每个销具有偏心地安装在销的顶表面处的突片。 凸片相对于销的顶部表面向上延伸。 定心机构还包括适于旋转每个销的销旋转机构。 销旋转机构使销在第一位置和第二位置之间旋转,在第一位置中,突片限定了大于衬底周长的外壳,其中突片限定了衬底的居中位置。 也可以为每个销提供嵌套屏蔽段的伸缩布置,以防止处理流体到达销的轴。 在一个方面,定心机构耦合到衬底处理位置的衬底支撑件,并且因此允许衬底在被降低到处理位置时居中。
