Appl. No.:

10/190001

Inventors:

Xiao Gordon Liu - Fremont CA, US
Wei Guo Liu - Sunnyvale CA, US

Assignee:

AXT, Inc. - Fremont CA

International Classification:

C30B011/06

US Classification:

117 81, 117 82, 117 83, 117223

Abstract:

Group III-V, II-VI and related monocrystalline compounds are grown with a rigid support of a sealed ampoule, carbon doping and resistivity control, and thermal gradient control in a crystal growth furnace. A support cylinder provides structural support for the combined sealed ampoule crucible assembly, while low-density insulating material inside the support cylinder deters convection and conduction heating. Radiation channels penetrating the low-density material provide pathways for radiation heating into and out of the seed well and transition regions of the crystal growth crucible. A hollow core in the insulation material directly beneath the seed well provides cooling in the center of the growing crystal, which enables uniform, level growth of the crystal ingot and a flat crystal-melt interface which results in crystal wafers with uniform electrical properties.

257 4, 257209, 257529, 257E2917

Abstract:

An electrically re-programmable fuse (eFUSE) device for use in integrated circuit devices includes an elongated heater element, an electrically insulating liner surrounding an outer surface of the elongated heater element, corresponding to a longitudinal axis thereof, leaving opposing ends of the elongated heater element in electrical contact with first and second heater electrodes. A phase change material (PCM) surrounds a portion of an outer surface of the electrically insulating liner, a thermally and electrically insulating layer surrounds an outer surface of the PCM, with first and second fuse electrodes in electrical contact with opposing ends of the PCM. The PCM is encapsulated within the electrically insulating liner, the thermally and electrically insulating layer, and the first and second fuse electrodes.

International Classification:

C30B035/00
C30B001/00

US Classification:

117/200000, 117/900000

Abstract:

An apparatus for producing large diameter monocrystalline Group III-V, II-VI compounds that have reduced crystal defect density, improved crystal growth yield, and improved bulk material characteristics. The apparatus comprises a crucible or boat, an ampoule that contains the crucible or boat, a heating unit disposed about the ampoule, and a liner disposed between the heating unit and the ampoule. The liner is preferably composed of a quartz material. When the liner and the ampoule are made of the same material, such as quartz, the thermal expansion coefficients of the liner and ampoule are the same, which significantly increases the lifetime of the liner and the single-crystal yield.

Abstract:

An apparatus and a method for growth of Group III-V monocrystalline semiconductor compounds in a closed system with a balanced pressure maintained between the inside of a sealed ampoule and a pressure vessel. The vapor pressure inside the sealed ampoule can be controlled by temperature, the amount of polycrystalline charge and an amount of material such as phosphorus inside the sealed ampoule. Filling and release of an inert gas is used to control the pressure in the pressure vessel.
