Abstract: In some implementations, one or more semiconductor processing tools may form a metal cap on a metal gate. The one or more semiconductor processing tools may form one or more dielectric layers on the metal cap. The one or more semiconductor processing tools may form a recess to the metal cap within the one or more dielectric layers. The one or more semiconductor processing tools may perform a bottom-up deposition of metal material on the metal cap to form a metal plug within the recess and directly on the metal cap.

Abstract: A control module may be used for raising and lowering a window shade. This configuration allows a user to pull the operating cord a predetermined distance to raise the window shade, then release the operating cord until it has retracted, and then pull the operating cord another predetermined distance to raise the window shade again. A brake mechanism is operably connected to a brake release and configured to lock or unlock the drive axle. A clutch is adapted to be mounted on the axle for selectively engaging the cord drum to the axle. The cord drum may rotate independent of the drive axle when a clutch is disengaged from the drive axle. As a result, movement of the operating cord will not cause the window shade to raise while the clutch is disengaged. When the clutch is engaged with the drive axle, the cord drum and adapter sleeve may rotate together to drive the rotation of the drive axle for raising the window shade.

Abstract: The present invention provides a double cell structure for window shade and its manufacture method for forming a substrate of double cell units. The substrate comprises first and second strip material bonded with each other, two lateral sides of the substrate being formed by first and second pleats. The substrate can then be cut to form multiple double cell units that are then stacked and bonded over one another for forming the double cell structure. In addition, the present invention also provides double cell structures for window shade.
