Title: Method and apparatus for measuring noise and method for reducing noise
Inventor: FUKUDA KEIKO
IPC: G01R29/26
Filed: 1994-03-24
Abstract: PURPOSE:To evaluate the effect of noise, generated from a digital circuit, on an analog circuit well by measuring the output voltage distribution of a voltage comparator at each time. CONSTITUTION:When a voltage comparator 20 and a digital circuit 7 are driven with a same frequency, a clock generating circuit 1 generates a clock for driving the circuit 7 and a clock for driving the comparator 20 through a time lag generating circuit 2. The comparator 20 is fed with a reference voltage from a reference voltage generating circuit 21 and an input voltage variable gradually around the reference voltage from an input voltage generating circuit 22 in order to measure the frequency distribution of erroneous function. Noise thus measured is collected by a data collecting unit 4 and the waveform is reproduced by a processor 5 before being presented on a display 6. This constitution facilitates concrete comprehension of noise waveform.

Abstract: PURPOSE:To obtain a device which is manufactured easily, also inexpensive, and has a high reliability, without requiring a specular surface working such as an optical polishing, etc. when sealing an image sensor, by filling a transparent resin between the image sensor and a lens array. CONSTITUTION:A transparent resin 35 such as epoxy or acryl, etc. is filled in a space between a substrate 31 surrounded by a supporting member 34 and a rod lens array 33. When packing the transparent resin 35, the rod lens array 33 is fixed in advance so that a distance between an optical axis direction center position P of the rod lens array 33 and an image forming surface (surface of a photoelectric converting element array 40) of an image sensor 32 becomes 1/2 of a conjugate length TC' of the rod lens array 33 in the transparent resin 35, and said resin is filled between the rod lens array 33 and the image sensor 32 after defoaming the transparent resin 35. Accordingly, an adjustment of an optical system is simplified remarkably, and its adjusting state is also converted easily to high accuracy.

Abstract: PURPOSE:To prevent the short-circuit between adjacent connecting wires and to contrive an increase in the number of the connecting wires by a method wherein conductor ribbons are formed integrally with a semiconductor chip on the peripheral part of the chip, electrode pads are arranged on the insides of these conductor ribbons and the ribbons and bonding wires, which are each connected to the electrode pad, are respectively provided extendedly in a state that a vertical distance exists between the ribbons and the bonding wires. CONSTITUTION:Parts of a circuit of a semiconductor chip 1 are connected electrically to the side of a PGA substrate 11 by conductor ribbons 2 and the residual parts of the circuit are connected to the side of the substrate 11 by bonding wires 4. The ribbons 2 are provided extendedly on almost the same plane as the surface of the chip 1, the wires 4 are provided extendedly in the form of a loop at positions higher than the surface of the chip and the ribbons 2 and the wires 4 respectively make the chip 1 connect electrically with the substrate 11. Accordingly, a trouble that both interfere with each other and are short-circuited is scarcely generated. Thereby, even in case the number of wires to be used for an electrical connection with the substrate 11 is increased in response to an increase in the density of the chip 1, this way can easily deal with this and can correspond to an increase in the density and the multipin formation of a semiconductor device.

Abstract: PURPOSE:To verify the polarized condition of a crystaline ingot by measuring the polarized state of the entire crystaline ingot without breaking the crystaline ingot itself in comparison with a sound velocity value proper to material under review with a velocity value of a ultrasonic wave traveling through the crystal ingot.

IPC: G03F7/00
Filed: 1990-03-06
Abstract: PURPOSE:To allow the correction of only the correcting part of a defective press plate without removing the press plate by applying a coating type photosensitive agent on the press plate and drying the coating, then bringing an original plate for correction into tight contact with the press plate, irradiating the press plate with the spot of high-intensity UV rays to expose the plate, developing the plate, and subjecting the plate to spot burning processing. CONSTITUTION:The coating type photosensitive agent is applied on the correcting part of the press plate and after the coating is dried, the original plate for correction is brought into tight contact therewith by hand. The correcting part is irradiated with the spot of the high-intensity UV rays by a device for irradiation with the UV ray spot and is thereby exposed. A developing soln. is then applied on the exposed part to develop the exposed part; thereafter, hot wind is locally blown to this part, by which the exposed part is subjected to the spot burning treatment. The coating type photosensitive agent to be used is of a UV ray decomposition type and the agent of a diazo system is adequately usable. A UV curing type photosensitive agent may be used at the time of the negative press plate. Only the defective part of the press plate is corrected in a short period of time in this way.
