Title: Field-effect transistor
Inventor: YAMAMOTO KAZUNORI
IPC: H01L29/80
Filed: 1981-11-20
Abstract: PURPOSE:To enable the preparation of E/D type FET in an epitaxial layer with very excellent controllability and in such a manner as suited for LSI, by making the thickness of a conductive layer adjustable while maintaining a planar structure. CONSTITUTION:An n type conductive layer 2 is formed on a semi-insulated substrate 1. The n type conductive layer 2 is formed of an epitaxial layer. Then, semi-insulated layers 10 and 10a are formed thereon. When GaAs is used, for instance, the semi-insulated layers 10 and 10a can be formed by the selective ion implantation of molecules, such as those of Cr, to serve as deep acceptors. By selecting a voltage for acceleration of implantation and a dose thereof appropriately, the thickness of semi-insulation is changed and the thickness of the conductive layer 2 is adjusted. Next, n<+> is formed in regions 11, 11a and 11b by the selective ion implantation. Subsequently, electrodes of sources 3, 6, drains 5, 8, and gates 4, 7 are formed. The thickness of each of under-gate conductive layers 2a and 2b is selected so as to meet the conditions as E-FET and D-FET.

CONSTITUTION:When the coordinate data Xn of hand-witten information are inputted from an input device to a register 8, coordinate data Xn-1 are outputted from the register 8, and coordinate data Xn-2 are outputted from a register 9. Difference arithmetic parts 10, 11 find out differences DELTAXn, DELTAXn-1 respectively on the basis of the coordinate data Xn-2 and inclination arithmetic parts 3, 4 find out DELTAYn, DELTAYn-1 by the difference arithmetic part of the Y coordinate data and operate the inclinations DELTAYn/DELTAXn, DELTAYn-1/DELTAXn-1 and comparator 5 compares both the inclinations. If both the inclinations coincide with each other as the result of comparison, coordinate data regarding the two segments as one segment are outputted, and in case of inconsistency, the coordinate data of the two segments are outputted. Consequently, the coordinate data of a node of two segments having the same inclinationis are not outputted and the output data are compressed.
