Title: Gaas field effect transistor
Inventor: SAITO AKIRA
IPC: H01L29/80
Filed: 1987-12-18
Abstract: PURPOSE:To prevent the deterioration of high frequency characteristics, by forming a leading-out electrode in the manner in which, from the end-portion of a gate electrode among electrodes, said electrode is led out along a chip surface without coming into contact with the chip, and reaches beyond the chip edge, and using said electrode as a bonding wire. CONSTITUTION:The end-portion 3A of a gate electrode 3 remains in the active layer of a crystal, and its tip width is made large. A leading-out electrode 4 is led out from the tip part. Along the chip surface the leading-out electrode 4 extends as far as the outside of chip edge, without coming into contact with the chip. By linking the leading-out electrode 4 to the inner lead of a case, the gate electrode 3 is connected with an external lead. Since the width of the end-portion 3A of the gate electrode 3 needs to be only a little wider than that of the leading-out electrode 4, the increase of capacitance is very little though the end-portion 3A situates on the active layer. Therefore parasitic capacitance except the capacitance of element electrode is remarkably decreased, and noise index can be improved.

IPC: H01L29/762
Filed: 1993-12-20
Abstract: PURPOSE:To ensure a transferred charge amount of in a horizontal CCD for a solid-state image pick up device without expanding its width. CONSTITUTION:In a solid-state image pick up device which is provided with a horizontal CCD of two-layered electrode two-phase drive, an electrode 1 in a first layer for the horizontal CCD is in a rectangular shape, and an electrode 2, in a second layer, which is overlapped with it is in a trapezoidal shape which is narrowed in a direction opposite to a transfer direction. A barrier region is formed of a channel provided with a potential gradient due to a narrow- channel effect caused by the shape of the electrode 2. Consequently, since the barrier region has a gradient in potential, the transfer efficiency of an electric charge is improved as compared with that in conventional cases.
