Abstract: A method for manufacturing a window for a polishing pad is disclosed. The method includes: a) mixing a curing agent with a polyurethane prepolymer having a temperature of 50° C. or higher to less than 100° C. to prepare a mixture; b) injecting the mixture into a mold heated to a temperature of 30° C. or higher to less than 100° C. to a thickness of 5 mm or less; c) demolding a polyurethane cured product from the mold; and d) processing the polyurethane cured product to a thickness of the window of the polishing pad. A polishing pad including the window is also disclosed.

Abstract: In one example, a semiconductor device can comprise a substrate, a device stack, first and second internal interconnects, and an encapsulant. The substrate can comprise a first and second substrate sides opposite each other, a substrate outer sidewall between the first substrate side and the second substrate side, and a substrate inner sidewall defining a cavity between the first substrate side and the second substrate side. The device stack can be in the cavity and can comprise a first electronic device, and a second electronic device stacked on the first electronic device. The first internal interconnect can be coupled to the substrate and the device stack. The encapsulant can cover the substrate inner sidewall and the device stack and can fill the cavity. Other examples and related methods are disclosed herein.

Abstract: A chip on film package includes: a base substrate having an output pad region; a plurality of output pads disposed in the output pad region of the base substrate, wherein the output pads are arranged in a zigzag configuration on the base substrate; a plurality of output pad wirings connected to the output pads, respectively; and a protection layer disposed on the output pad wirings. The protection layer is disposed on the output pad wirings disposed between two adjacent output pads, arranged in a first direction.
