    摘要: A semiconductor wafer is disclosed that includes a plurality of fields, including a plurality of alignment fields. Each alignment field includes a plurality of intra-field small scribe lane primary mark (SSPM) overlay mark pairs there around. The SSPM mark pairs allow for in-situ, non-passive intra-field alignment correction. In one embodiment, there may be between two and four alignment fields, and between two and four SSPM mark pairs around each alignment field. The SSPM marks of each mark pair may be extra scribe-lane marks.

    摘要: A power supply apparatus includes a main body, a power input device, a first power output device and a second power output device. The power input device is coupled to an input terminal of the main body. The first power output device includes a first cable and a first connector. The first cable is interconnected between a first output terminal of the main body and a first surface of the first connector. An extension part is extended from the first surface of the first connector. The second power output device includes a second cable and a second connector. A first surface of the second connector is suppressed by the extension part of the first connector to facilitate securely fixing the first connector and the second connector in a power socket, so that a regulated output voltage is outputted from the first and second output devices to the power socket.

    摘要: A tool and method for placing an identifying mark on a semiconductor wafer has a bundle of optical fibers that can be illuminated in a pattern representing an identifying character. Light from the fibers is focused on a photoresist layer during wafer manufacture and a pattern of dots is etched into the wafer to represent the character. The dots are too small to be seen with the human eye but the character can be read by a human or by a machine. The character is etched as part of a conventional etch step in manufacturing the wafer and it is easily repeated as a series of manufacturing steps obscure the original mark.

    摘要: This invention describes a method of making intra-field corrections to the alignment of a step and repeat projection system used to expose image fields on an integrated circuit wafer. A first pattern having first image fields and first alignment marks is formed on a wafer. A mask having a second image field and second alignment marks is projected on the wafers, having a layer of photoresist formed thereon, using light which will not expose the photoresist. The relative location of the second alignment marks to the second image field is the same as the relative location of the first alignment marks to the first image field. A detectors, comprising an interferometer, determines the displacement vector between the first alignment marks and the corresponding second alignment marks. The displacement vectors are fed to a computer which computes a translation correction, a rotation correction, and a magnification correction for the alignment of the mask to the wafer. After the corrections are made the photoresist is exposed by projecting light which will expose the photoresist.

    摘要: A method includes forming a plurality of image sensors on a front side of a semiconductor substrate, and forming a dielectric layer on a backside of the semiconductor substrate. The dielectric layer is over the semiconductor substrate. The dielectric layer is patterned into a plurality of grid-filling regions, wherein each of the plurality of grid-filling regions overlaps one of the plurality of image sensors. A metal layer is formed on top surfaces and sidewalls of the plurality of grid-filling regions. The metal layer is etched to remove horizontal portions of the metal layer, wherein vertical portions of the metal layer remain after the step of etching to form a metal grid. A transparent material is filled into grid openings of the metal grid.
