Title: Semiconductor device
Inventor: SUGAHARA KAZUYUKI
IPC: H01L29/80
Filed: 1989-10-30
Abstract: PURPOSE:To enable the rapid formation of a depletion layer inside a high resistivity layer and to improve a semiconductor device more in switching speed by a method wherein at a least a hole is provided to the high resistivity layer extending from a surface side to an insulating base, and a control electrode layer is formed on the high resistivity layer and inside the hole concerned. CONSTITUTION:When a zero or a positive voltage is applied to a gate layer 7 as keeping a first N-type single crystal silicon layer 3 at a zero potential and applying a positive potential to a second N-type single crystal silicon layer 4, electrons from the first N-type single crystal silicon layer 3 pass through an intrinsic layer 5, and a current flows. On the other hand, the first N-type single crystal silicon layers 3 and 4 are kept at a zero and a positive potential respectively, and a negative potential is applied to the gate layer 7 keeping the layers 3 and 4 in this state. In this state, electrons in the intrinsic layer 5 around the gate layer 7 are expelled to make the layer 5 depleted. At this point, a part of the intrinsic layer 5 is replaced with the gate layer 7, so that a negative voltage is applied to the intrinsic layer 5 in a lateral direction. By this setup, a depletion layer is rapidly formed in the intrinsic layer 5, so that a semiconductor device of this design can be improved in switching speed.

Abstract: PURPOSE:To satisfactorily execute a clamping work by moving a measuring instrument provided with an electromagnetic wave emitter and a receiver, emitting an electromagnetic wave into a bulk substance, receiving a reflected wave from a boundary surface to a substrate, and measuring the variation of electric characteristics caused by ground clamping of the bulk substance. CONSTITUTION:By a movable measuring instrument which is provided with an electromagnetic wave transmitter 6 and a receiver 7, a measurement for the clamping degree of the bulk substance is executed. An electromagnetic wave W from this transmitter 6 is emitted to soil 2 from a transmitting antenna 4, and a reflected wave from the boundary to the substrate 1 is received by a receiving antenna 5 and led to the receiver 7. A signal received by this receiver 7 is sent to an analyzer 8, in which electric characteristics (for instance, the velocity of propagation, dielectric constant, attenuation factor, etc.) of the soil 2 by the electromagnetic wave W are calculated. From these electric characteristics, the clamping state of the soil 2 is detected, and displayed on an indicator 9. Accordingly, by measuring continuously and automatically the variation of the characteristic value, a soil structure which is clamped uniformly can be constructed.
