Abstract: An airflow management system and/or method used in particle abatement in semiconductor manufacturing equipment. In particular, the apparatus disclosed is capable of creating and managing a carefully controlled particle free environment for the handling of semiconductor wafers or similar articles. The apparatus is particularly suited to be used as an interface between an equipment front end module (EFEM) and a vacuum loadlock chamber or other such article of process equipment. The apparatus also enables relative motion between enclosures while maintaining a particle free environment utilizing a moving air diffuser mounted to an interface panel.

Abstract: Described are an apparatus and a method for cooling a web. The apparatus includes an inner cylinder having a void therein and configured for coupling to a gas source. The apparatus also includes an outer cylinder having an inner surface, an outer surface to support a web and apertures between the inner and outer surfaces. The outer cylinder rotates about the inner cylinder so that gas provided to the void of the inner cylinder flows through the apertures that are adjacent to the void and passes to the outer surface of the outer cylinder to increase the heat transfer between the web and the outer cylinder. The volume of gas introduced into the vacuum deposition chamber during a process run is thereby limited. Advantageously, the apparatus enables higher deposition rates and increased productivity.

Abstract: Method and apparatus for use in setting up workpiece treatment or processing equipment. A disclosed system processes silicon wafers that are treated during processing steps in producing semiconductor integrated circuits. The processing equipment includes a wafer support that supports a wafer in a treatment region during wafer processing. A housing provides a controlled environment within the housing interior for processing the wafer on the wafer support. A mechanical transfer system transports wafers to and from the support. A wafer simulator is used to simulate wafer movement and includes a pressure sensor for monitoring contact between the simulator and the wafer transfer and support equipment. In one illustrated embodiment the wafer simulator is generally circular and includes three equally spaced pressure sensors for monitoring contact with wafer transport and support equipment.

Abstract: An end effector for installation on a robotic arm for transporting a plurality of semiconductor wafers from one location to another features a ceramic end effector body portion that includes a plurality of wafer engaging fingers that each feature wafer support pads. The wafer support pads are adapted to support a semiconductor wafer surface, and at least one of the support pads has a vacuum orifice. The body portion features an interior vacuum passageway having a first end that is adapted to connect to a vacuum source and a second end that terminates at the vacuum orifices such that a reduced gas pressure at the first end causes a vacuum to be exerted at the vacuum orifices. The interior passageway is formed from a groove in the end effector body portion and an end effector backplate that is sealingly connected to the end effector body portion to completely cover the groove from the first end to the second end. The ceramic body portion can be made of alumina or silicon carbide.

Abstract: A variable aperture assembly (30) is provided for controlling the amount of ion beam current passing therethrough in an ion implantation system (10). The aperture assembly (30) comprises an aperture (44) defined by opposing first and second aperture plates (44A, 44B) through which an ion beam passes; control arms (46A, 46B) connected, respectively, to the first and second aperture plates (44A, 44B); and an aperture drive mechanism (36) for simultaneously imparting movement to the control arms in opposite directions, to adjust a gap (50) between the aperture plates (44A, 44B) to thereby control the amount of current passing through the aperture (44). Each of the opposite directions in which the control arms move is generally perpendicular to an axis along which the ion beam passes. A control system (120) is also provided for automatically adjusting the aperture gap (50) based on inputs representing actual ion beam current passing through the implanter, desired ion beam current, and aperture position.
