Title: Measurement of growth situation of epitaxial growth layer
Inventor: KOBAYASHI NAOKI
IPC: H01L21/20
Filed: 1990-09-01
Abstract: PURPOSE:To obtain the display information on the growth situation of epitaxial growth layers with high precision by entering specific linear polarized light in a specific direction to the surface of a semiconductor crystal substrate so that intensity display signals may be obtained from the reflected light on the surface of an epitaxial growth layer. CONSTITUTION:While a semiconductor layer is grown as an epitaxial growth layer 2 from top of the surface of a semiconductor crystal substrate 1, a laser beam L11 having an energy of 2-5eV and linearly polarized is entered with a plane including the optical axis AI and the electric field vector EI kept vertical to the surface 1a of the semiconductor substrate 1. Reflected light LR from the surface 2a of the epitaxial growth layer 2 is received by a photoelectric transducer 6, which provides and amplifies output S6 corresponding to the intensity of the reflected light LR to output it as display signal S5 of reflected light intensity. This way can provide display information on growth situation of epitaxial growth layers with much higher precision.

Title: Array type infrared detector
Inventor: MAEJIMA YUKIHIKO
IPC: H01L27/14
Filed: 1985-10-17
Abstract: PURPOSE:To reduce leakage current of a P-N junction, to improve a resolution and to simplify the manufacturing steps by forming a mask provided with a terminal to which a voltage of a conductor of the shape for interrupting incident infrared light is to be applied to a region except the P-N junction through an insulating film on a semiconductor photodetecting surface side. CONSTITUTION:A P-type HgCdTe film 1, an N-type HgCdTe film 2, a substrate 3 of a detector, a passivation film 4, N-type side and P-type side electrodes 5, 6 and a gate 8 are formed. Since the infrared ray is incident from the opposite side to a substrate, the substrate is not necessary formed of transparent CdTe for the infrared light. When the gate 8 uses, for example, aluminum of approx. 5,000Angstrom  thick, it does not pass infrared light or visible light. Accordingly, the gate for reducing the leakage current of a P-N junction is used also as a mask for preventing photon from being incident to a portion except the P-N junction. An electric connection of the detector with an exterior is obtained by the portion projected at a part of each electrode gate. Thus, since the dark current of the detector is reduced by a voltage applied to the gate, the sensitivity of the detector itself is improved.

Abstract: PURPOSE:To realize the sure automatic steering control of a vehicleby detecting a mark put on the surface of a wall set at the side of a driving course via a TV camera mounted on the vehicle body. CONSTITUTION:A mark 4 is put in parallel and discretely at a point apart from the straight line part of a scheduled driving course by a known distance. Then the mark 4 is detected by a TV camera 2. The distances between an image pickup surface and the right/left sides of the mark 4 as well as between the image pickup surface and the center of the mark 4 are set at da - dc and therefore specified by the side lengths (a) - (c) respectively. The mark size L1, the distance L2 between the mark 4 and the driving course, the key point 8 of a vehicle body, the position L3 of the camera center axis set to the point 8, and the position L4 of the camera image pickup surface are all known. Thus the horizontal displacement (l) and the attitude angle psiof the vehicle body can be obtained at the time point when the camera 2 fetches the mark image. The changes of the displacement (l) and the angle psi are operated with detecting the moved distances of the right and left fixed wheels 9 by an encoder and fed back to the (l) and psi. At the same time, the driving speed and the driving direction and other control information on the vehicle are fetched selectively from the mark 4. Then a controller 6 changes the code No of s display device 5 at a place where a different action is required.
