Abstract:
A semiconductor device carrier tape with image sensor detectable dimples is disclosed. The dimpled carrier tape is formed of a flexible strip of material. A plurality of pockets are disposed spaced apart along the length of the flexible strip of material. Each pocket is configured to hold a semiconductor device. A dimple is formed in each of the plurality of pockets where each dimple has a peripheral edge and a bottom surface. Detection of the dimple by an image sensor facilitates alignment of a semiconductor device with the pocket and precise placement of the semiconductor device in the pocket.
Abstract:
A stack of chips is formed by a first integrated-circuit chip and a second integrated-circuit chip. The chips have opposing faces which are separated from each other by an interposed spacer. The spacer is fastened by adhesion to only one of the opposing faces. The opposing faces are fastened to each other by a local adhesive which is separate from spacer.
