Abstract: PURPOSE:To reduce a leaking current, by forming a first implanted layer by implanting ions of boron or proton, forming a second semiconductor layer by implanting ions of silicon or sulfur or selenium at a part longitudinally neighboring the first layer, and then forming a third semiconductor layer by implanting ions of boron or proton or aluminum at a part longitudinally neighboring the second implanted layer. CONSTITUTION:The first layer 3 is formed by implanting ions of B<+> or H<+> in a semiinsulating GaAs ground crystal 1. The second layer 2 is formed by implanting ions of Si<+> or S<+>, or Se<+>, or the like at the part longitudinally neighboring the first ion implanted layer. The device is heat-treated at a high temperature of 700-900 deg.C so as to activate the implanted ions. Furthermore, the third  layer 4 is formed by omplanting B<+> or H<+> ions at the part longitudinally neighboring the second layer. Thereafter heat treatment at 700-900 deg.C is performed  so as to activate the implanted ions. By using a GaAs wafer obtained in this  process, an MESFET is manufactured by the same processes as those of the  conventional method.

Title: Mechanical oscillator
Inventor: INOUE TAKESHI
IPC: H03H9/00
Filed: 1981-03-06
Abstract: PURPOSE:To obtain a subminiature low frequency mechanical oscillator by decreasing the stiffness of a supporting line. CONSTITUTION:A piezoelectric thin film 21 is polarized as shown by arrows. When it is energized electrically from electric terminals 24 and 24', high-frequency-side energizing in secondary mode of inflection determined by the shape and size of an oscillator is carried out and mode conversion is performed; and energizing in mode of rigid body rotation shown by a broken line at an extremely low frequency side is carried out and a supporting line 23 is twisted to cause resonance. The resonance frequency of the rigid-body rotation mode is determined by stiffness regarding the torsion of the supporting line 23 while the resonance frequency of the inflection mode of a sound piece is determined by the size and shape of the sound piece. Therefore, even if the size of a part for rigid body rotation is reduced, the frequency is decreased freely by reducing the stiffness of the supporting line 23.

Title: Semiconductor laser element
Inventor: MORIMOTO TAIJI
IPC: H01S5/00
Filed: 1986-02-17
Abstract: PURPOSE:To obtain a semiconductor laser having a window region and long-life with excellent controllability by depositing the multilayer crystal of a semiconductor laser onto a substrate formed in juxtaposed manner to a V-shaped striped groove as a current path through a liquid-phase epitaxial growth method and using the whole as a semiconductor laser element. CONSTITUTION:A pair of grooves 22', 23' are shaped in response to regions as striped parallel grooves formed in a post-process to a P-type GaAs substrate 10. An N-type GaAs current blocking layer 11 is grown in an epitaxial manner onto the substrate 10 by employing a liquid-phase epitaxial growth method so that the grooves 22', 23' are buried completely and the layer thickness of the current blocking layer 11 is brought to 0.8mum at the position of a striped groove 12 formed in the post-process. The V-shaped striped groove 21 having 3mum stripe width and 1mum depth is shaped at a position on the central-line symmetric axis of parallel grooves 22, 23 through etching. Consequently, currents required for oscillating laser beams concentrate to the V-shaped striped groove 21 and flow, thus inhibiting reactive currents which do not contribute to oscillation. Accordingly, a section in the vicinity of the end surface of a laser is formed in window structure, and the absorption of laser beams is suppressed by the window structure, thus acquiring high-output oscillations.
