Title: Manufacture of solid-state laser and its manufacture
Inventor: MATSUNO AKIRA
IPC: H01S3/16
Filed: 1987-06-30
Abstract: PURPOSE:To manufacture a solid-state laser with high luminous efficiency and reliability by the processing steps of depositing a first electrode and a first oxide on a substrate, depositing a thin single-crystal silicon film and a light- emitting layer on the first oxide, and depositing a second electrode on the light-emitting layer in such a manner that opposite edges of the light-emitting layer form reflecting surfaces. CONSTITUTION:The opposite sides of a light-emitting layer 15 which a luminescence center impurity was doped in a semiconductor as a base metal is treated as reflecting surfaces 18a and 18b. The other surfaces excluding these two surfaces are enclosed with insulating films 13 and 16. A fixed voltage is applied through the insulating films 13 and 16 to the layer 15 to emit light, causing laser resonance by two reflecting surfaces 18a and 18b. In such a solid-state laser, a single-crystal silicon layer 14 lies between the insulating film at the lower layer and the light-emitting layer. For example, the first electrode 12 and first insulating 13 are formed on a substrate 11. After an amorphous silicon is filmed over the first insulating film 13, it is fransformed to a single-crystal layer 14 by the laser annealing method, and thereon the layer 15 is formed through the expitaxial growth method.

Title: Displacement measuring method
Inventor: KITA YASUO
IPC: G01D5/347
Filed: 1982-09-20
Abstract: PURPOSE:To measure fine displacement easily with high precision by measuring the relative displacement of a moving plate from a substrate from the shift in phase of a wave of array-order variation of the amount of information occurring to an element A or B owing to the mutual operation between the elements A and B. CONSTITUTION:When the moving plate 20 is irradiated with uniform light from above its top surface side, respective photosensors 11 of the substrate 10 photodetect the light through small holes 21 of the moving plate 20 and their outputs vary in array order as shown by black dots. Namely, array-order variation of the photosensors 11 arrayed on the substrate 11 shows a one-cycle wave having maximum values at both ends and a minimum value in the center. When the moving plate 20 is moved slightly in the array direction of the small holes 21, the photosensors 11 of the substrate 10 vary in the amount of photodetection and a wave shown by white dots is obtained. Namely, the slight displacement of the moving plate 20 causes the large shift in the phase of the wave of the array-order variation of the photosensors 11. Further, the phase of the wave of the array-order variation of the photosensors 11 is calculated with precision more than a-tenth the array pitch of the photosensors 11 by processing of the outputs of the photosensors 11 statistically and finding a maximum likelyhood point.

Title: Memory check system for computer system
Inventor: NAKANO HIROSHI
IPC: G06F12/16
Filed: 1990-06-21
Abstract: PURPOSE:To shorten the starting time despite the large capacity of a memory contained in a computer system by checking the working only in the area of an internal memory indispensable to the start processing and then reading the data to carry out the start processing. CONSTITUTION:When a power supply is applied to a system, a CPU 1 carries out the start processing based on a system start program stored in an internal ROM. A hard disk 4 storing the data to be read into a main memory 3 is set in a data readable state via a disk controller 5. Then the working is checked for the least data necessary for start of the system of the memory 3, i.e. an area necessary for read of a system program which controls the system, i.e. an area A. Then the system program is read out of the disk 4 and sent to the memory 3 via the controller 5. As a result, the starting time is never increased and the operating efficiency is improved even in a computer system where a large capacity memory is applied.

IPC: H01L21/48
Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To prevent breakages, without generating clearances between an electrode and a solder bump and improve the productivity by providing a curvature on the tip end of a solder bump formed on a substrate and flattening a joint surface between the solder bump and substrate. SOLUTION: In a bump transfer substrate 11, a solder bump 12 is formed on a base material 13 by forming successively a curvature part 12d on a columnar part 12c, and a curvature is formed on the tip end 12a of the curvature part 12d. The tip end 12a is a plane, having a curvature of the tip end of the curvature part 12d, and the solder bump 12 is provided with the columnar part 12c, whose bottom is flat and which is placed on the one main surface 13a of the base material 13. When the solder bump 12 is transferred to an electrode on a semiconductor element using the bump transfer substrate 11, the electrode and solder bump 12 can be joined with each other without generating a clearance therebetween, even if a recessed part is formed in an insulating film and the electrode on the semiconductor element because the tip end 12a of the solder bump 12 has a curvature.  Thus, voids can be eliminated, and the productivity be improved.

Abstract: PROBLEM TO BE SOLVED: To enable high-accuracy eccentricity measurement regardless of radius of curvature of a measured surface and the effective diameter by varying the angle of converging and intersecting split coherent light beams to interfere with each other, and measuring the eccentricity of the measured surface according to the obtained interference information. SOLUTION: Light beams 2 from a laser 1 are split into light beams 2a, 2b by a light beam splitting element 3 to be incident on a condensing lens 5 through a two- light beams width converting part 4. The position where two light beams 2a, 2b are converged and to intersect each other substantially agrees with the curvature center position 13 of a measured surface 8', two reflected light beams overlap each other to produce interference fringes, which are detected by a photo detecting means 9. When the condensing lens 5 is fine adjusted so that the contrast of the interference fringes is maximum, the position where two light beams 2a', 2b are converged to intersect substantially agrees with the center of curvature of the measured surface 8'.  A rotary table 6 is rotated, a signal from the photo detecting means 9 and a signal from a rotary bearing detecting means 7 are operated by an operating means 10, and finally the displacement data of the whole periphery is obtained to find the magnitude and bearing of eccentricity of the measured surface 8'.
