IPC: B60R16/02
Filed: 1987-09-02
Abstract: PURPOSE:To attain simplicity and low cost by replacing a communication unit of a part not necessarily needing a response signal with a reception exclusive unit in simple configuration not provided with a transmission function. CONSTITUTION:Time division multiplex communication is applied by the bus system of contention control, branch points 23-25 are arranged on a bus 1 and multiple units 3, 4 for transmission/reception and a multiple unit 5 exclusive for reception are connected to the branch points 23-25.

Abstract: PURPOSE:To obtain a vertical field-effect transistor high in dielectric breakdown strength by a method wherein a source and a gate are provided onto a part of the surface of a semi-insulating substrate and a drain is formed on the rear of the substrate corresponding to the position where the gate and the source are provided. CONSTITUTION:Three grooves 2 d in depth are formed on an n<->type silicon substrate 1 through a RIE method. Next, a laminated body 5 consisting of a silicon oxide film 3 and a polycrystalline film 4 is formed on the surface of the substrate 1. Lastly, a two-way diode of n<+>pn<+> is formed in such a direction as the junction is made to intersect with the grooves 2 through a usual method. In this case, the effective length L of the pn<+> junction is made to be longer than the usual one by six times the depth d of the grooves 2. Therefore the operational resistance r of the two-way diode is made to be reduced to about l/(l+6d) times the usual one, and thus a FET can be improved in dielectric breakdown strength.
