Abstract: PURPOSE:To obtain an excellent dielectric breakdown strength distribution and improve the reliability, by oxidizing after growing a first silicon nitride film and oxidizing after growing a second silicon nitride film and forming a multilayered capacitor insulating film. CONSTITUTION:After selectively growing a LOCOS oxide film 2 necessary for element isolation on a silicon substrate 1, a first polysilicon electrode 3 is formed. Then, after growing a first silicon nitride film, the surface of the silicon nitride film is oxidized. In such a manner, a first capacitor insulating film 51 is formed. After growing a second silicon nitride film on the first capacitor insulating film 51, the surface of the silicon nitride film is oxidized and thereby a second capacitor insulating film 52 is formed. Thus, a pinhole in the silicon nitride film can be buried more effectively and the capacitor insulating film having an excellent dielectric breakdown strength can be formed.

Abstract: PURPOSE:To make an illuminance distribution uniform on a work face and to obtain a high-accuracy pattern by a method wherein an aspherical lens wherein the principal-ray tilted angle characteristic of a radiant illumination ray as the radiant ray of an illumination system coincides with the principal-ray tilted angle characteristic of an incident ray by the projection lens of a projection system is installed in the illumination system. CONSTITUTION:The following are installed with reference to a pattern mask 5: an illumination system S which is constituted of a light source 1 for exposure use, a shutter 2, a fly-eye lens 3, a collimator lens 4 and the like; and a projection system T constituted of a projection lens 6. In such a projection-type aligner, an aspherical lens 8 wherein the inclination of the principal ray of exposure light coincides with that of an incident ray by the projection lens 6 is installed in the illumination system S. Thereby, the exposure light for irradiating a work face through the projection lens does not deviate from an ideal principal ray with reference to the projection lens. Consequently, the work face is irradiated at a uniform illumination distribution.

Title: Particulate measuring instrument
Inventor: OKADA RYOZO
IPC: G01N21/53
Filed: 1987-07-07
Abstract: PURPOSE:To detect particulates of smaller size efficiently at a large flow rate by arranging >=2 kinds of stray light removing means in a detection cell. CONSTITUTION:Slit 50 and 52 are arranged in the detection optical system path of a detection cell 40 where a photodetector 30 for detecting scattered light is arranged, a corrugated wall surface part 60 is formed partially, and a reflection preventive coating 70 is arranged at least at part of it. In this case, >=2 kinds of stray light removing means are used in combination in the cell 40. Consequently, light beams (b) and (c) among stray light components shown by a dotted line are removed, but it is difficult to remove a stray light component (a) which is incident directly on the detector 30 from a point R. Therefore, even if stray light is generated, it can be removed as much as possible, so the S/N ratio of a detection signal can be improved by reducing a noise level.

Title: Semiconductor memory device
Inventor: FURUYAMA TOORU
IPC: G11C11/409
Filed: 1979-12-26
Abstract: PURPOSE:To realize a high-speed operation and low power consumption for a semiconductor memory device, by giving a consideration to the relation of arrangements among the sense amplifier, the bit line and the input/output signal line each. CONSTITUTION:The input/output signal line I/O and the bar I/O are connected directly to the nodes N1 and N2 of the sense amplifier 8A via the MOSFET21 and 22 each but with no intervention of the bit line pair of BL1 and bar BL2 plus bar BL1 and BL2 each. With this connection, either one of the signal line I/O and the bar I/O which are precharged according to the write contents O of the memory cell MC3 is discharged to perform a reading. In this case, only the bit line pair BL2 and bar BL2 are connected to the nodes N1 and N2 based on the line address, and thus only the line BL2 is discharged. Thus only one bit line is discharged to reduce the power consumption caused by the charge/discharge. At the same time, the access time is also reduced owing to a small discharge capacity.

Title: Transversal type automatic equalizer
Inventor: YOSHIDA ATSUSHI
IPC: H03H21/00
Filed: 1987-07-09
Abstract: PURPOSE:To improve the system throughput by shifting a tap coefficient of an automatic equalizer forward when the line characteristic is the best so as to reduce the delay in the device. CONSTITUTION:The input signal is given to a delay device 101 causing a delay of Tsec and the outputs D0-D19 are multiplied with tap coefficients C0-C19 being outputs of a tap coefficient generator 102 at a multiplier 103 and the result is given to an accumulator 104. On the other hand, the tap coefficient C is converted into an absolute value by an absolute value converter 105 and when all the absolute value of the tap coefficients from the 0th to the Lth tap coefficients close to the input in general are smaller than the predetermined value, the control section 106 makes the 0th-the tap coefficient of the (N-L-2)th equal to the tap coefficient of the (L+1)th-(N-1)th, and makes the (N-L-1) th-(N-1)th tap coefficients zero. Thus, the reduction in the delay in the device is attained and the system throughput is improved.

Filed: 1987-07-07
Abstract: PURPOSE:To quickly execute a program having many conditional branches of floating- point by encoding state information of an additional processor to a code corresponding to the branch condition to send it to a central processing unit at the time of detecting a state transfer instruction by an instruction decoding part. CONSTITUTION:An instruction decoding part 8 monitors the instruction issued from a central processing unit 2 to an additional processor 3 through an instruction bus 5; and when a data transfer instruction accompanied with floating-point arithmetic is issued from the central processing unit 2, data transfer between the additional processor 3 and the central processing unit 2 is executed through a data transfer part 6. When it is detected by the instruction decoding part 8 that the central processing unit 2 issues an operation state transfer instruction to the additional processor 3 for the purpose of performing conditional branch, a state encoding part 7 reads out the operation state information of the additional processor 3 through a data bus 4 and converts the operation state of the additional processor 3 to a code, which indicates whether each branch condition is satisfied or not, and adds this code to operation state information and transfers this information to the central processing unit 2 through the data bus 4.
