Title: Insulated gate type transistor and charge transfer device using the same
Inventor: ITOU MINORU
IPC: H01L29/762
Filed: 1982-07-22
Abstract: PURPOSE:To obtain charge transfer property with less loss by forming stepwise or oblique gradient at the voltage of the channel part of an IGFET from a source toward a drain and connecting in cascade multistage. CONSTITUTION:A gate oxidized film under a central gate electrode 35 is formed to be thicker directly under gate electrodes 34, 36 of both sides at N type source 31 and drain 32 in such a manner that the electrodes are independently superposed partly. The same voltage is applied to the electrodes 35, 36, and a voltage higher than this voltage is applied to the electrode 34. When a voltage VGS between a gate and a source is near a threshold value, the voltage 38 of the channel in the saturated range exhibits stepwise gradient, a drain current feasibly flows by the influence, and gm remarkably increases. On the other hand, the influence of the drain layer to the channel formed by electrode 34 to the variation in the expansion of a depletion layer is remarkably reduced by the buffer effect of the channel produced by the electrodes 35, 36, and dynamic drain conductance gds is reduced. When these FETs are connected in cascade in multistage, charge transfer with less transfer loss can be performed.
