    Abstract: There have been cases where the wirings are not led out when a semiconductor chip comprising a conventional macro is mounted on a package substrate. The macro-cell block is a macro-cell block formed polygonal having a plurality of sides and formed in a semiconductor chip, and is characterized by comprising a signal terminal portion, a power terminal portion, and a ground terminal portion, which are connected to the outside of a semiconductor chip, wherein the signal terminal portion is disposed along one side of the plurality of sides, and the power terminal portion is disposed along a side different from the side where the signal terminal portion is disposed, and the ground terminal portion is disposed along a side different from the side where the signal terminal portion is disposed.

  • Patent number: 6888956
    Abstract: A fingerprint authentication apparatus has a combined visible/infrared light source, which illuminates a finger placed on an optical image sensor with both infrared light and visible light. The optical image sensor has a block with infrared sensitivity and a block within infrared sensitivity, and generates a fingerprint image from light scattered by the finger. The infrared sensitivity of the infrared-sensitive block of the optical image sensor is such that a clear image is obtained from a living organism, and an unclear image is obtained from a replica. If the finger is an actual living finger, the fingerprint images from both blocks are clear, but in the case of a replica, the image from the block having infrared sensitivity is clear, and the image from the block without having infrared sensitivity is unclear.
