摘要： A semiconductor device comprises a substrate the surface of which is formed of an insulation region, a high resistance active layer of a first conductivity type formed on the substrate, a first semiconductor region of the first conductivity type having an impurity concentration higher than that of the active layer and selectively formed on a surface of the active layer, an emitter region of the second conductivity type selectively formed on a surface of the semiconductor region, a collector region of the second conductivity type selectively formed on a surface of the active layer, and a base contact region of the first conductivity type selectively formed on a surface of the active layer in separation from the emitter region and the collector region, respectively. When an inversion layer is formed at an interface between the insulation region and the active layer due to the voltage of the substrate, the semiconductor region suppresses an emitter current flowing via the inversion layer thereby allowing the emitter current to flow on the surface side of the active layer.

摘要： A high-breakdown-voltage semiconductor device has a first offset layer and a second offset layer the dosage of which is higher than that of the first offset layer. When the gate is in the ON state, the first offset layer functions as a resurf layer. When the gate is in the OFF state, part of the charge in the first offset layer is neutralized by a drain current flowing through an element having a low ON-resistance, however, the second offset layer functions as a resurf layer. When the drain current is [Acm−1], the amount of charge of electrons is q[C], and the drift speed of carriers is &ugr;drift[cms−1], the dosage n2 of the second offset layer is given by n2≧ID/(q &ugr;drift) [cms−2].

摘要： An n-type buffer layer and a p-type base layer are formed in the surface of the n.sup.- -type drift layer. A p.sup.+ -type drain layer is formed in the surface of the n-type buffer layer. An n.sup.+ -type source layer and a p.sup.+ -type contact layer are formed in the surface of the p-type base layer. A main gate electrode is arranged to face, through a gate oxide film, a surface of the p-type base layer which is interposed between the n.sup.+ -type source layer and the n.sup.- -type drift layer. An n-type relay layer is formed in the surface of the n.sup.- -type drift layer to face the n.sup.+ -type source layer through the p-type base layer under the main gate electrode. The n-type relay layer extends from the n.sup.- -type drift layer into the p-type base layer. The n-type relay layer decreases the channel resistance.

摘要： A red/green test apparatus for determining whether spectacle lenses or contact lenses are under-correcting or over-correcting has a case 1. The case 1 is divided into left and right parts by a partitioning plate 2 and a lamp 3R for red and a lamp 3G for green are disposed to the left and right of this partitioning plate 2; and a red film 5 is provided on the left side of the partitioning plate 2 and also a green film 6 is provided on the right side of the partitioning plate 2, both via an opalescent screen 4 on a front surface of the case 1. Two visual fixation marks 8 and 9 of identical shape and size form black displays at positions on the front surfaces of the films 5 and 6 corresponding to the lamps 3R and 3G, and a switching circuit is provided to cause the lamp 3G to either light or flicker for a fixed time, then cause the lamp 3G and the lamp 3R to light simultaneously. This makes it possible to perform a red/green visual target test in a state in which the unconscious accommodation of the crystalline lens performed by the test subject is suppressed as far as possible.
