Title: Manufacture of window-structured semiconductor laser element
Inventor: KURIHARA HARUKI
IPC: H01S5/00
Filed: 1989-10-11
Abstract: PURPOSE:To realize mass-production easily without any need for high accuracy in the depth of etching and thickness of liquid crystal growth by forming a tripe structure, eliminating a substrate or a laser. Operation layer and by forming a window, mutually diffusing the constituent atoms between one or both of a first and a second carrier confinement layers and an active layer. CONSTITUTION:After partially eliminating the surface of a P-conductivity type substrate 1 so that a mesa part remains at a part corresponding to an optical waveguide path excluding a window region, an N-conductivity type current-prevention layer 2 is allowed to grow. A stripe-shaped groove 3 is provided on the surface and a current path hole 4 is exposed and formed. Then, a P-conductivity type lower clad layer 5, a P-conductive type optical waveguide path 6, a P-conductivity type active layer 7, an N-conductivity type upper clad layer 8, and an N-conductivity type ohmic contact layer 9 are laminated. After laminating an SiO2 film 10 on the surface, an ohmic contact layer 9 which is positioned corresponding to a window region is eliminated with it as a mask. Then, the SiO2 film 10 is used for a diffusion mask for performing zinc diffusion, thus forming a zinc diffusion region 11. The activation layer 7 becomes transparent and a window region is formed since Al mol ratio increases. The SiO2 film 10 is dissolved, upper/lower metal electrodes 12 and 13 are installed, and mirror surfaces 14 and 15 are formed on the side surface by cleavage for completing the process.

Abstract: PURPOSE:To improve high frequency characteristics and the like of a delta-doped FET by using a simple means, by providing a channel layer composed of InXGa1-XAs layers which sandwich a Si monoatomic layer formed by delta-doping, in the midway of thickness. CONSTITUTION:A channel layer composed of InXGa1-XAs layers 3, 5 is formed, between which a delta-doped Si layer 4 formed by delta-doping is sandwiched in the midway of thickness direction. The saturation speed vS of InXGa1-XAs, adopted here, is very large as compared with GaAs and the like, so that the cutoff frequency fT necessarily increases, and the high frequency characteristics are surely improved. Since the GAMMA.L band gap of InXGa1-XAs is wide, characteristics in a high electric field region can be improved. Further, by changing the value (x) of InXGa1-XAs, two-dimensional concentration nS of electron traveling in channel can be controlled.

Title: Method for lifting single crystal using double crucible and said double crucible
Inventor: KAWASAKI AKIHISA
IPC: C30B15/12
Filed: 1985-11-25
Abstract: PURPOSE:To obtain a single crystal with less generation of crystal defects and having the uniform concn. of impurities by fixing the inner crucible to the outer crucible, and using the double crucible having a through hole for a raw material melt at the lower part of the side wall of the inner crucible and a through hole for a sealant at the upper part. CONSTITUTION:The raw material melts 24 and 25 are respectively charged in the inner crucible 21 and the outer crucible 22, and the melts are covered with liq. sealants 26 and 27. The level of the outer melt 24 is flush with that of the inner melt 25, and the level of the outer sealant 26 is flush with that of the inner sealant 27. A lifting shaft 29 is lowered while being rotated, and a seed crystal 28 is dipped in the raw material melt 25, and seeding is carried out. A single crystal 30 is grown in succession to the seed crystal 28. Since the cross section of the crystal 30 is increased while the shoulder part is formed, the level of the sealant 27 in the crucible 22 is raised. However, since the sealant 27 flows out into the outer crucible from the through hole 33 for a sealant, the levels of the sealants 26 and 27 are made flush with each other. When the shoulder forming is finished the levels of the sealants 26 and 27 and the levels of the raw material melts 24 and 25 remain flush with one another respectively in the inner and outer crucibles. Since the condition of the melt in the inner crucible is stabilized, the generation of crystal defects is reduced.

IPC: G11B23/03
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To disable those not having a key for releasing a lock mechanism from write and read by setting a lock mechanism part to the inside of an outer frame of a medium storing a magnetooptic disk and prohibiting the medium from being inserted to an insertion opening of a magnetooptic disk drive in a lock state. SOLUTION: When a key 5 is inserted to a key hole of a lock mechanism part 3 set to an outer frame 9 storing a magnetooptic disk 7 and turned by 90 deg. to change a lock part 6 in a lock state, a screen plate, which is built in the lock mechanism part 3 and moves interlocking with the lock part 6, moves to a position to obstruct the movement of a shutter hook part 2. The shutter hook part 2 and a coupled shutter 1 are fixed accordingly, so that a medium cannot be inserted to an insertion opening of a magnetooptic disk drive. The key 5 is manufactured differently to meet an individual medium and therefore data can be protected for every medium. Specifications in other parts than the lock mechanism part 3 are shared among general media, thereby eliminating a change to a mechanism of the drive.
