Abstract: In a method of manufacturing a semiconductor device, a conductive pattern is formed in a surface region of a dielectric layer, a mask pattern including an opening over the conductive pattern is formed over the dielectric layer, a part of the conductive pattern is converted into a high-resistant part having a higher resistivity than the conductive pattern before the converting through the opening, and the mask pattern is removed.

Abstract: A forming method of a ReRAM array includes steps as follows: Firstly, a first pulse is applied to a first ReRAM unit in the ReRAM array. Afterwards, a second pulse is applied to the first ReRAM unit, wherein the electrical property of the first pulse is opposite to that of the second pulse. Then, a verification pulse is applied to the first ReRAM unit to verify whether the first resistance value of the first ReRAM unit passes a preset threshold. When the first resistance value passes the preset threshold value, a third pulse is applied to the first ReRAM unit, wherein the first pulse and the third pulse have the same electrical property, and the first pulse has a voltage value substantially the same to that of the third pulse.

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.
