Title: Process for recovering substrates
Inventor: TAKADA SATORU
IPC: H01L21/02
Filed: 1996-10-03
Granted: 1999-06-21
Abstract: A process comprising removing surface layer materials from the wafer by inducing micro-fractures in the surface using a rotating pad and an abrasive slurry until all of the surface layer materials are removed; and chemically etching the surfaces of the wafer until all micro-fractures are removed therefrom. Edge materials are removed by abrasive tape. Wafer thickness reduction during recycling is less than 30 microns per cycle. One of the front and back surfaces of the wafer substrate is polished, any dots or grooves being on the non-polished side. The abrasive slurry contains more than 6 volume percent abrasive particles, and the abrasive slurry has a viscosity greater than about 2 cP. The preferred pad comprises an organic polymer having a hardness greater than about 45 on the Shore D scale, optimally a polyurethane. The pressure of the pad against the wafer surface preferably does not exceed about 3 psi. Preferably, the chemical etching solution contains potassium hydroxide. An acidic solution can then be applied to the wafer surface. The reclaimed silicon wafer has a matted side having etch pits which does not exceed 20 microns in width, an average roughness not exceeding 0.5 microns and a peak-to-valley roughness not exceeding 5 microns. Any laser markings from the original wafer are present on the matted side of the wafer.

Title: Memory address generator circuit and semiconductor memory device
Inventor: OHNO KAZUKI
IPC: G11C11/408
Filed: 1999-03-17
Granted: 2001-07-21
Abstract: A semiconductor storage device (1100) having a burst mode capability for accomplishing a rapid read/write operation is disclosed. Included is a memory address generator circuit (100) having an address counter (102) which latches and increments the n least significant bits of a start address containing m bits, the address counter (102) producing a count value. An address latch (104) latches the m-n most significant bits of the start address, and an end address arithmetic circuit (106) produces a burst end address by subtracting 1 from the start address n least significant bits. A comparator circuit (108) generates a burst end signal (BSTEND) based on the comparison of the count value and the burst end address, the comparison being done by way of a generation of coincidence signals (K0-K2) by coincidence detector circuits included in the comparator circuit (108). Read/write addresses are produced for the semiconductor storage device where the m-n bits in the address latch (104) form the more significant bits of the read/write address and the count value form the less significant bits of the read/write address. The read/write operation for the memory is completed by stopping the increment operation of the address counter (102) when the burst end signal is generated.

Title: Method and apparatus for evaluating aberrations of optical element for use with optical device
Inventor: TAKADA KAZUMASA
IPC: G01M11/02
Filed: 1999-07-27
Granted: 2002-02-01
Abstract: A method for evaluating aberrations of an optical element such as optical head for use with an optical system such as DVD. In this method, light is transmitted through the optical element and then diffracted into 0, ±1, ±2, ... order diffraction lights, for example. Among others, first and second lights (e.g., 0 and +1, 0 and -1, +1 and -1, or 0 and ±1 order diffracted lights) are overlapped to form an image shared by the first and second lights. Then, light intensity at first and second points in the shared image are detected. At this moment, light intensity at the first and second points are changed. Then, a phase difference in light intensity of between first and second points is determined. Using the phase difference, aberrations of the optical element are determined.

Title: A semiconductor device
Inventor: SUGIURA SOICHI
IPC: H01L21/8246
Filed: 1999-08-02
Granted: 2001-01-11
Abstract: This invention provides a good electrical connection between a conductor 56 such as a lead electrode of the DRAM capacitor storage node and a semiconductor region 61 such as a source of the selective transistor. Form a thin film 41 of 0.1 nm to 2 nm in thickness, having a crystal structure different from that of a conductor 56 and a semiconductor region 61, between the conductor and the semiconductor region. The presence of the thin film 41 prevents the epitaxial growth from starting from the interface between the conductor 56 and the semiconductor region 61 and reduces the crystal defect formation and growth near the interface. As a result, the leakage current at the pn junction due to crystal defect can be reduced.

The insertion object electrode 5 of the upper layer is connected directly with the insertion object electrode 1 of the lower layer without using the disposed wire electrode so as to form the insertion object electrode 7. Accordingly, the disposition of Levenson device becomes possible and the pattern density can also be increased, such that semiconductor integrated circuit device with high integration can be realized.
