Title: Inspecting device for semiconductor wafer
Inventor: OOTA KOUZOU
IPC: H01L21/66
Filed: 1984-11-30
Abstract: PURPOSE:To enable to perform the automatic focussing of an image pick-up device and the measurement of the thickness of a wafer by a method wherein a Z-stage is controlled in accordance with the maximum value of the harmonic ingredient of the image signal obtained by the image pick-up device provided opposing to a semiconductor wafer receptacle stand. CONSTITUTION:The harmonic ingredient of the image signal for one picture component of the ITV of an image pick-up device is picked up by an HPE, and it is integrated by an integration circuit INTG. The output of said integration circuit is A/D converted, and retained on the memory circuit to be contained in a control circuit CONT. Subsequently, the integral output of the harmonic ingredient is calculated and memorized successively by controlling a Z-stage and changing in the amount of the prescribed distance (DELTAZ) for the image pick-up device ITV. Thus, the memorized integral output INTG indicates the characteristics having the focussed point Zo as the peak for the distance of movement (z) of the Z-stage of a wafer receptacle stand CT, and the profile of a circuit pattern is made clear by the image signal of the image pick-up device ITV as the image pick-up device is in focus. The thickness of the wafer can be measured by performing the above-mentioned operation at several points on the surface of the semiconductor wafer.

Title: Coordinate input device
Inventor: YOSHIZAWA SATOSHI
IPC: G06F3/038
Filed: 1987-10-09
Abstract: PURPOSE:To perform the shift of a coordinate input device only in the selected direction regardless of the shift of a keyboard or a mouse (coordinate input device) by adding a means to the coordinate input device to cut or select the input of signals in the direction of an optional axis. CONSTITUTION:A switch 4 is added to a mouse to cut the input of the direction of X or Y axis. When the switch 4 is turned on, a signal 12 is set at logic '0' and a signal 11 received from an encoder 7 is cut off. Then the signal 12 is set at logic '1' when the switch 4 is turned off. Thus the signal 11 is outputted through a signal line 3. In such a way, the switch 4 functions to select one of plural coordinate signals of a coordinate input device for output. Thus it is possible to avoid the shift of a cursor caused by an inadvertent operation, etc., and to ensure a quick and accurate shift of coordinates.

Abstract: PURPOSE:To form a high-luminous output and short-wavelength semiconductor laser without increasing the series resistance by making an impurity diffuse in the clad layer in such a way that the carrier density in the vicinity of the active layer becomes smaller. CONSTITUTION:The temperature of the substrate is made to rise for about 20hr up to reach 70 deg.C, then Al and Ga are respectively irradiated at 1,100 deg.C and 950 deg.C for forming the N type clad layer. At this time, Sn is diffused first as an impurity at 850 deg.C at the same time as the time the Al and Ga are irradiated. In such the state, the irradiation of Al and Ga is performed and when the prescribed time, when is required by the time the N type clad layer is formed and reaches the vicinity of the active layer, elapses to the clad layer to be formed, the first diffusion temperature of Sn is lowered to 750 deg.C. In this state, the impurity Sn is diffused throughout the prescribed time to be required by the time the N type clad layer is formed. When the N type clad layer is formed, the GaAs active layer is formed. Then, the P type clad layer is formed. In this case, Be is diffused as an impurity at temperatures of 800 deg.C or thereabouts. Furthermore, the gap layer is formed. In this case, the temperature for the formation of the gap layer is set at 850 deg.C, though the impurity Be keeps being diffused.
