Abstract: A precision pump system is described that includes a motor driver for accurately and repeatedly delivering process fluid, and uses a pumping fluid with minimal process fluid loss to a fabrication process. A method for automatically evacuating gas from the process fluid to be dispensed as part of a recirculation process is also described.

Abstract: A precision pump system having a motor driver for accurately and repeatedly delivering process fluid, (e.g., photo chemicals) using a pumping fluid with minimal process fluid loss to a fabrication process and whereby the motor driver can be easily and quickly replaced without interrupting the fluid flow path. This is accomplished with the use of a gas removal reservoir having at least one vertical partition therein and at least one free end near a top side of the gas removal reservoir where both the input and output to the gas removal reservoir are located on a bottom surface and a pumping fluid reservoir that are associated with the pump, either integrated with the pump or closely adjacent. In addition, this precision pump system can be remotely monitored, viewed and controlled over the Internet. In addition, trapped process fluid within a downstream filtering block can be recirculated to the gas removal reservoir when trapped gas in the filter is removed.

Abstract: A flyswatter (10) having an elastically deformable swatting member (16) with a plurality of protrusions (20) formed thereon. The protrusions (20) are spaced apart on the swatting member (16), and have a height somewhat less than the height of the insect. When the swatting member (16) is struck on an object upon which the insect rests, the protrusions (20) contact the object, and the swatting member (16) elastically deforms and bows outwardly and strikes the insect without flattening or squishing the insect.

Abstract: A method and system for dispensing a precise amount of a chemical used in the fabrication of semiconductors utilizes rolling membrane pump and calculates an amount by which to change a dispense based at least in part on a predicted membrane flex. Membrane flex is predicted, at least in part, by the shape of the membrane, a volume of liquid to be dispensed and a pressure during dispense.

Abstract: A method and system for dispensing a precise amount of a fluid utilizing a rolling membrane pumping system is disclosed. In the preferred embodiment, the method comprises calculating an amount by which to change a dispense based at least in part on a predicted membrane flex if a particular dispense is other than a first dispense, wherein said predicted membrane flex is based at least in part on a maximum pump chamber pressure during the first dispense; calculating an amount by which to change a dispense based at least in part on a shape of the membrane if a particular dispense is a first dispense; moving a piston in the pumping system based at least in part on the calculated amount; opening an output valve of the pumping system; monitoring the pump chamber pressure to detect a sudden decrease in said pump chamber pressure to signal a mechanical failure in the pumping system; and determining a maximum pressure in the pump chamber during the movement of the piston.
