Semiconductor Devices With Improved Heat Dissipation And Method For Fabricating Same
US Patent:
7692289, Apr 6, 2010
Filed:
Aug 12, 2002
Appl. No.:
10/217089
Inventors:
Li Cai - Shakopee MN, US
James M. Van Hove - Eagan MN, US
Amanda Jo Jepson - Monticello MN, US
James M. Van Hove - Eagan MN, US
Amanda Jo Jepson - Monticello MN, US
Assignee:
ADC Telecommunications, Inc. - Eden Prairie MN
International Classification:
H01L 23/10
US Classification:
257706, 257712, 257E23101
Abstract:
The present invention is directed to improving the efficiency of removing heat from semiconductor devices. In addition, the method of manufacturing the improved devices has the potential of eliminating a key step in the traditional production process where the chips are highly susceptible to mechanical damage. A semiconductor element includes a semiconductor substrate having a heat removal side and a heat producing region, and at least one superstrate semiconductor layer defining the heat producing region. The heat removal side of the semiconductor substrate includes at least one recess region which extends closer to the heat-generating region than the remainder of the heat removal surface.
High Responsivity Ultraviolet Gallium Nitride Detector
US Patent:
5278435, Jan 11, 1994
Filed:
Jun 8, 1992
Appl. No.:
7/895350
Inventors:
James M. Van Hove - Eagan MN
Jon N. Kuznia - Bloomington MN
Donald T. Olson - Roseville MN

Assignee:
APA Optics, Inc. - Blaine MN
International Classification:
H01L 2714
US Classification:
257184
Abstract:
The invention is an Al. sub. x Ga. sub. 1-x N ultraviolet detector with extremely high responsivity at over 200 to 365 nanometers and a very sharp long wavelength cutoff. The active layer for the sensors is a single crystal Al. sub. x Ga. sub. 1-x N preferably deposited over a basal plane sapphire substrate using a switched atomic layer epitaxy process.
Narrow Band Algan Filter
US Patent:
5182670, Jan 26, 1993
Filed:
Aug 30, 1991
Appl. No.:

Assignee:
APA Optics, Inc. - Blaine MN
International Classification:
G02B 528, F21V 904, H01L 2714
US Classification:
359359
Abstract:
The invention is a filter device of at least two layers, the first layer of Al. sub. x Ga. sub. (1-x) N and the second layer of Al. sub. y Ga. sub. (1-y) N wherein x and y may have any value from 0 to 1. The invention may be used as a fixed wavelength or tunable wavelength filter or in ultraviolet detectors and laser devices, among other systems. Applications for the invention include detection of UV radiation in environments having a high level of incident infrared and visible radiation, as well as applications requiring detection of UV emission when no other radiation is present.
