Title: Measuring device
Inventor: KARASAWA WATARU
IPC: G01N21/93
Filed: 1987-04-23
Abstract: PURPOSE:To enable the high magnification detecting of a matter to be measured, by carrying/positioning the matter to be measured within the usable range of an optical system and using this optical system to picture the matter to be measured and displaying it on a TV monitor whenever a state of the matter to be measured is required to be detected. CONSTITUTION:A semiconductor wafer whose pre-alignment is finished is carried/ positioned on a measurement stage by a carrier arm 5. Whenever a state of a chip on measurement is required to be observed, the semiconductor wafer 8 on measurement is moved within a usable range of an optical system 6, and its position alignment to the optical system is performed on the basis of a predetermined reference point. Subsequently, light from a light source 9 is radiated on a surface of the semiconductor wafer 8 whose state is required to be observed. Since the image picturing by the use of a CCD camera 12 is occasionally hindered due to a dark field of vision, light sources 9 are installed on a plurality of positions, for example, on three positions. The light source 9 installed above perpendicularly to the semiconductor wafer 8 is used on a bright field of vision. In succession, a CCD camera is used to picture the surface of this semiconductor wafer 8 through a half mirror 10, and this pictured image is displayed on a TV monitor 11.

And, for instance, when it is necessary to fit a tape reel whose thickness is thicker than that of the tape reel having been used so far, a worker turns a stopper 63 to project it from the male screw part 62 by the amount required for the thickness of the tape reel. And, the male screw part 62 is fitted in the female screw part 60. In this case, the end of the stopper 63 abuts on the abutting part 65 of the tape reel fitting plate 14 to stop farther proceeding, thus the space just required for fitting the tape reel can be obtained. The above procedure is repeated for each time the thickness of the reel changes.

Abstract: PURPOSE:To contrive the improvement of the element characteristics by preventing a narrow channel effect by selectively diffusing impurities into the semiconductor substrate using a slope of the resit layer covering the nitride and oxide films on the substrate as a mask. CONSTITUTION:On a P type substrate 6, an oxide film 7' is formed, on which a nitride film 8 and further a photoresist layer 9 are formed. Next, after forming the layer 9, the film 8 is etched into the predetermined pattern using the remaining layer 9 as a mask. Then, a resist layer 10 is spread over the whole surface of the substrate 6 including the film 8. Then the boron ions are implanted through the layer 10 to form the part 4' to become an isolation diffusion layer. Consequently, an inclined part of an edge 12 on the layer 10 functions as a mask for ion implantation so that a boundary of the ion implantation exists apart from and toward the outside of the undr-part of the film 8 by a pattern size Y as compared with a mask pattern by self-aligning. As a result, interference to the channel region by the region 4' can be eliminated.

Abstract: PURPOSE:To improve the high-speed responsiveness by contriving that a control voltage applied to a control electrode has a phase difference corresponding to the vibration delay of a carrier with respect to the voltage applied to an oscillating electrode, thereby suppressing an alleviating vibration phenomenon. CONSTITUTION:A pair of oscillating electrodes 7, 8 for oscillating and a plurality of control electrodes 9, 10 for applying a control voltage are provided. The control voltage applied to the control electrode has a phase difference corresponding to the vibration delay of a carrier with respect to the voltage applied to the electrodes 7, 8. An undoped GaAs layer 3 is an active region to form the active region by an undoped Ga1-xAlxAs (x=0.3) layer 4; the flow of electrons is concentrated to be injected to the active region. For example, with the applied voltage as sinusoidal wave a voltage V1 is applied to the electrodes 7, 8 of the first set, and a voltage V2 is applied to the electrodes 9, 10 of the second set. Then, the current flowing to the region is represented by the sum of two sinusoidal waves. The light emission is delayed to the current of the sum, and electrons are diffused in a space, but the reduction in the electrons in the active region due to the diffusion is supplemented by the phase delay of the electrodes of the second set to suppress the alleviating vibration phenomenon.
