Title: Semiconductor device and manufacture of the same
Inventor: ISHIDA TSUTOMU
IPC: H01L29/78
Filed: 1992-05-15
Abstract: PURPOSE:To avoid a defect in stability of operation due to drop of operation speed resulting from higher resistance of offset region and accumulation of unwanted charges into the offset region in a field effect type semiconductor device having an offset gate structure. CONSTITUTION:A drain 3 and a gate electrode 8 are separated as much as an offset region to form an offset gate structure. Moreover, at a part of the substrate 1, namely the offset region between the drain 3 and gate electrode 8, a PN junction 13 consisting of p- type low impurity concentration layer 11 and n<+> type high impurity doped layer 12 provided on the surface of the layer 11 is formed. Since the PN junction 13 is formed in the offset region, a current flowing when this semiconductor device is actually operated, that is, positive charge generating such current is rejected by a depletion layer generated in the PN junction 13 at the offset region and passes through the internal side of the substrate 1.

Title: Character display device
Inventor: TAKAKOSHI AKIRA
IPC: G09G1/16
Filed: 1980-10-23
Abstract: PURPOSE:To ensure a stable detection for the position of the displayed character, by changing over a ordinary display and a constant luminance display while a light pen is used and thus setting the characters displayed on a cathode-ray tube under the constant luminance display. CONSTITUTION:When a light pen 9 is pressed to a displayed character on a cathode-ray tube 8, the detection signal of the luminous point of the displayed character is supplied to a light pen control circuit 2 and a changeover circuit 14 from the pen 9. The circuit 14 is usually connected to a luminance control circuit 11 by the switch signal of the pen 9 and then changed over to the side of the circuit 11 consisting of a variable resistance 12 and a resistor 13. Thus the luminance of the displayed character is set at a high level. In such way, the position of a displayed character can be stably detected to prevent the deterioration of the fluorescent film of a cathode-ray tube.
