Patent JP-S63260180-A (JP)
Title: Semiconductor device
Inventor: KATO RIICHI
IPC: H01L29/76
Filed: 1987-04-17
Abstract: PURPOSE:To reduce leakage currents by forming an impurity adding layer having a conductivity type reverse to source-drain layers into a wide band gap region under the source-drain layers. CONSTITUTION:Second conductivity type layers are shaped into a barrier layer 3 while brought into contact with source-drain layers 5, 6. That is, p-n junctions are formed to sections adjacent to the source-drain layers 5, 6 in the barrier layer 3 having a wide band gap. When source-drain and anode layers 5, 6 take an n-type, p-type layers 7, 8 shaped under the n-type source-drain layers 5, 6 in the RST (real spatial transition) element function as barriers to the transfer of electrons to the barrier layer 3 from the source-drain layers 5, 6 while working as a sufficient barrier even at the time of operation at room temperature because the potential of conduction bands in p regions of the p-n junctions is elevated at a value in an extent corresponding to the band gap under the state of thermal equilibrium. Accordingly, leakage currents between source-anode and drain-anode are reduced, thus acquiring excellent element characteristics without depending upon an operating temperature.

Abstract: PURPOSE:To make it possible to shift by slight force, realize smooth positioning and consequently contrive to improve quality and accuracy by a method wherein at least one of a pair of molds is supported under floating state by means of pressure fluid. CONSTITUTION:Pressurized air is fed through the vent path 61 of a press lower platen 6 into the recessed part 71 on the underside of a lower mold platen 7 so as to generate the buoyancy, which is slightly larger than the total weight including the lower mold platen 7, a lower mold 9 and guide bushings 10, in order to keep the lower mold platen 7 under floating state, which allows to have degrees of freedom in X, Y and Z directions. After that, the lower mold platen 7 is pressurized by the press lower platen 6 through hydraulic pressure so as to pressurize an upper mold 4 and the lower mold 9 to each other to work a workpiece. The utilization of pressure oil is also possible instead of pressurized air as floating source.
