Title: Signal processing circuit for magnetic sensor
Inventor: MASUDA NOBORU
IPC: G07D7/04
Filed: 1994-06-20
Abstract: PURPOSE:To provide a signal processing circuit for a magnetic sensor without being affected by the influence of the dispersion of magnetic resistance elements, temperature fluctuation and the gap change of the magnetic resistance elements and an object to be detected. CONSTITUTION:Magnetic detection signals by the magnetic resistance elements 2a and 2b are amplified in an operational amplifier 7 and added to a peak holding circuit 8. The peak holding circuit 8 holds the peak value of the amplified magnetic detection signals and resets the holding state of the peak value when the magnetic detection signals drop to a reset level supplied beforehand. A differentiation circuit 10 differentiates the output signals of the peak holding circuit 8. By the differentiation, a falling waveform part at the time of the reset of the peak holding circuit is obtained as a steep failing pulse waveform. An invertible amplifier circuit 11 inverts a differentiation waveform and adds it to a comparator circuit 12 and the comparator circuit 12 discriminates the level of the steep pulse waveform at the time of the reset by the differentiation, shapes the waveform and outputs it as the digital detection signal of magnetic information.

Inventor: WATANABE NOBUHISA
IPC: G01B11/00
Filed: 1993-06-30
Abstract: PURPOSE:To provide a method for measuring camera fitting position simply and accurately. CONSTITUTION:A mounting head is attached with a measuring jig in which first and second reference marks are prepared on its head as a reference on the position almost corresponding to the fitting position and the position opposite to a camera respectively. The first reference mark is recognized by a parts recognition camera to find out a coordinate value as a reference for the mounting head, and after the mounting head is moved so as to position the second reference mark just above the parts recognition camera, the lower side of the second reference mark is recognized by the parts recognition camera, and the coordinate value after the movement of the mounting head is found out on the basis of the recognized result and the coordinate value of the mounting head. Then, the accurate distance between the reference marks is obtained through the coordinate value and the upper side of the second reference mark is recognized by a board recognition camera. The recognized result and accurate distance between the reference marks are joined together so as to accurately obtain the fitting position between the mounting head and the board recognition camera.

Title: Aligner and manufacture of element using the same
Inventor: MORI TETSUYA
IPC: G03F9/00
Filed: 1993-06-30
Abstract: PURPOSE:To obtain a reticle signal having a stable intensity, which does not depend on the reflectivity of the surface of a wafer, by a method wherein when a pattern on the surface of a reticle is exposed on the wafer surface, a laser beam for illuminating the reticle illuminates the reticle without the intermediary of the wafer. CONSTITUTION:A laser beam emitted from a laser 4 is split into reflected light and transmitted light by the wave front split surface of a beam splitter 20. The reflected light forms a slit image on an alignment mark on a wafer 2 and moreover, is scattered and diffracted by the alignment mark on the wafer 2 to incide in a wafer signal detection system and the relative position of the split image to the alignment mark is detected. On the other hand, the trasmitted light is reflected to the side of a reticle 3, is transmitted an alignment mark on the reticle 3 and illuminates the alignment mark, is incided on a reticle signal detection system 11 and the position of the reticle is detected. Thereby, a reticle signal having a stable intensity, which does not depend on the reflectivity of the wafer surface, is obtained and the reticle can be aligned with the wafer with high accuracy.

Title: Optical amplifier
Inventor: TAMURA YASUAKI
IPC: G02F1/09
Filed: 1989-06-26
Abstract: PURPOSE:To realize optical amplification which does not depend upon a plane of polarization by passing a light beam to be amplified through a semiconductor laser reciprocally and allowing the beam to have mutually orthogonal planes of polarization on the going path and return path. CONSTITUTION:Light which is made incident on a port 106 passes through a port separator 101 and then made incident on and amplified optically by the semiconductor laser 102. The optically amplified light is made incident on a Faraday rotator 104 to have its plane of polarization rotated by 45 deg., and then projected. The projected light is returned to the rotator 104 through a reflector 105 to have the plane of polarization rotated by 45 deg. in the same direction. Thus, the plane of polarization is rotated by 90 deg. while the light passes through the rotator 104 once reciprocally. The light travels in the laser 102 in the opposite direction and is amplified. Thus, the light which is made incident on the port 106 is amplified irrelevantly to the plane of polarization and outputted from a port 107.

Abstract: PURPOSE:To improve a performance of or yield of a semiconductor device by a method wherein a leading or deepest end of V-channel in the base plate of the semiconductor device is made to have a round form. CONSTITUTION:On N<+> type Si base plate 1 is overlapped P layer 2, P<-> layer 3, channel cut 4, separate insulative layer 5, N dispersion layer 8 and SiO2 film 9.

When the liquid becomes higher by approx. 100mum than the film surface, the supply of the WF6 is stopped. Then, a laser beam irradiated from a pulse laser beam source 1 is radiated to form a contact hole.

IPC: H01L21/3213
Filed: 1992-06-19
Abstract: PURPOSE:To make it possible to form a polycrystalline Si multilayer interconnection which prevents the growth of a horn and provides excellent breakdown strength by implanting ions into the surface layer of a first polycrystalline Si layer or the edge end of the surface layer so as to produce further enhanced amorphous properties. CONSTITUTION:An oxide film 2 is formed on a silicon substrate 1 where a first polycrystalline Si layer 3 is deposited thereon. Then, an amorphous region 4 is formed on the surface layer of the first polycrystalline Si layer 3 by implanting ions. After the formation of the amorphous layer, a polycrystalline Si electrode pattern is formed on the surface. With the patterned first polycrystalline Si layer as a mask, an exposed portion of the first oxide film is wet-etched so that the Si surface may be exposed. Then, the exposed Si surface is thermally oxidized, thereby forming a second oxide film 5. Since the surface layer of the first polycrystalline Si layer is turned into an amorphous state, there is no grain field, which prevents the growth of a horn.
