Abstract: PURPOSE:To improve the uniformity and controllability of a drain current by forming a undoped GaAs layer on a first n-type GaAs layer, and forming a recess thereon. CONSTITUTION:A high resistance GaAs buffer layer 2 is formed on a semi- insulating GaAs substrate 1, a silicon-doped first n-type GaAs layer 3 is formed on the layer 2, and a undoped GaAs layer 4 is formed. Then, a silicon-doped second n-type GaAs layer 5 is formed on the layer 4, and the layer 4 is etched from above to form a recess 6. Thereafter, aluminium is deposited on the recess 6 formed on the layer 4 to form a gate electrode 8, and a source electrode 10 and a drain electrode 11 are formed on the layer 5, thereby forming a field effect transistor. Thus, a drain current is not affected by the etching amount of the recess, thereby improving the uniformity and controllability of the drain current.

Filed: 1987-03-09
Abstract: PURPOSE:To simplify software and to make the contents of memories coincident by providing a means transferring all data of oneself to other memories by means of the transfer means of a common bus if a memory receives a transfer request and becomes a transfer source. CONSTITUTION:If a CPU5a reads data, data is read from a shared memory device 1a which is connected to the input output bus of oneself. If the CPU5a writes data in the shared memory, data is written only in the shared memory device 1a. When data is written at such a time, the shared memory device 1a holds an address and data at that time, and outputs a write request to the common bus 6 at a timing different from that the CPU5a writes. When the exclusive right of the common bus 6 is obtained, said device outputs the address and data which have been held on the common bus 6. Furthermore, it outputs the write signal and executes writing until all the shared memory device 1a-1d including oneself. Consequently, data in all the shared memory devices coincide after a prescribed time.
