Abstract: A method for metallization during fabrication of an Integrated Circuit (IC). The IC includes a semiconductor wafer having a back surface and a front surface. The method includes etching a via hole through the semiconductor wafer. After this, a seed metal layer is deposited on the back surface of the semiconductor wafer. Thereafter, a photoresist layer is deposited on the back surface of the semiconductor wafer such that the via hole remains uncovered. After depositing the photoresist layer, a metal layer is formed along the walls of the via hole to electrically connect the back surface and the front surface of the semiconductor wafer. Finally, the photoresist layer is removed subsequent to forming the metal layer.

Abstract: A chute opener for opening a chute of a grain trailer is provided. The chute opener uses a motor coupled to a motor gear to drive a shaft gear. The shaft gear drives a crank shaft coupled to the chute of the grain trailer. The gears can be disengaged to enable manual operation of the chute by a hand crank. A position sensor can be provided which determines a position of the shaft gear even when disengaged from the drive gear to maintain accurate chute positioning information.

Abstract: Apparatus for retaining a side edge of a tarpaulin along a side portion of an open-topped box such as a truck box, wherein the tarpaulin includes a rigid rod connected along its side edge. The apparatus includes a bracket for attachment to the side of the box. A clamp arm is pivotally mounted to the bracket for movement about a pivot axis between a closed clamping position for securing the rod and tarpaulin side edge in fixed relation to the clamp arm and side portion of the box and an open position for releasing the rod and tarpaulin side edge. A clamp arm latch is pivotally mounted so that it can be manually shifted between a latched position wherein the clamp arm is secured in the closed position and an unlatched position wherein the clamp arm is free to pivot to the open position.
