US Patent:

6727117, Apr 27, 2004

Filed:

Nov 7, 2002

Appl. No.:

10/291126

Inventors:

John Washington McCoy - San Diego CA

Assignee:

Kyocera America, Inc. - San Diego CA

International Classification:

H01L 2144

US Classification:

438106, 257684, 257746

Abstract:

A semiconductor package for power transistors of the LDMOS type has a metallic substrate with a die mounted directly thereon, lead frame insulators mounted thereon adjacent the die and a plurality of leads mounted on the insulators and electrically coupled to the die by bond wires. The substrate includes a body having opposite surfaces comprising pure copper layers, and with the body interior being at least partially comprised of a copper/diamond composite so as to act as a heat spreader and provide improved heat removal and low thermal expansion, as well as an electrical connection for the die. The body may be entirely comprised of a copper/diamond composite, or it may be comprised of a copper/tungsten composite having a copper/diamond composite insert therein. The copper/diamond composite is comprised of diamond particles within a copper matrix. In a method of making the copper/diamond composite, diamond particles are coated with multiple layers of elements or inorganic compounds, mixed with a dry-processing binder and compacted in a die under pressure to form a compacted body.

Filed:

Dec 19, 2008

Appl. No.:

12/317170

Inventors:

Norbert Elsner - La Jolla CA, US
John W. McCoy - San Diego CA, US

International Classification:

F25B 21/02

US Classification:

62 32

Abstract:

A high-temperature thermoelectric module. The module includes a two part molded egg-crate for holding in place and providing insulation and electrical connections for a number of thermoelectric n-legs and p-legs. A first part of the egg-crate is comprised of a ceramic material capable of operation at temperatures in excess of 600 C. and a second part comprised of a thermoplastic material having very low thermal conductivity. In preferred embodiments the high temperature ceramic is zirconia and the thermoplastic material is DuPont Zenite. The thermoelectric legs are also comprised of high-temperature and low-temperature material. In preferred embodiments the high temperature thermoelectric material is lead telluride and the low temperature material is bismuth telluride. In preferred embodiments metal felt spacers are provided in each leg to maintain proper electrical contacts notwithstanding substantial temperature variations. Preferably the module is sealed in an inert gas filled insulating capsule.

International Classification:

H01L 35/20

US Classification:

136239

Abstract:

A long life, low cost, high-temperature, high efficiency thermoelectric module. Preferred embodiments include a two-part (a high temperature part and a cold temperature part) egg-crate and segmented N legs and P legs, with the thermoelectric materials in the three segments chosen for their chemical compatibility or their figure of merit in the various temperature ranges between the hot side and the cold side of the module. The legs include metal meshes partially embedded in thermoelectric segments to help maintain electrical contacts notwithstanding substantial temperature variations. In preferred embodiments a two-part molded egg-crate holds in place and provides insulation and electrical connections for the thermoelectric N legs and P legs. The high temperature part of the egg-crate is comprised of a ceramic material capable of operation at temperatures in excess of 500 C. and the cold temperature part is comprised of a thermoplastic material having very low thermal conductivity.

Abstract:

A segmented lead telluride egg-crate thermoelectric module. In preferred embodiments N legs and P legs are segmented into at least two segments. The segments are chosen for their figure of merit in the various temperature ranges between the hot side and the cold side of the module. In preferred embodiments a low-temperature egg-crate, molded from a liquid crystal polymer material, having very low thermal conductivity holds in place and provides insulation and electrical connections for the thermoelectric N legs and P legs at the cold side of the module. A castable ceramic capable of operation at temperatures in excess of 500 C. is used to provide electrical insulation between the legs at the hot side of the module.

International Classification:

H01Q 136
H01Q 140
H01Q 142

US Classification:

343895

Abstract:

A small and durable antenna for use with radio and microwave communications is formed as a helical conductor contained in a multilayered non-ferrite ceramic chip. The dielectric constant of the ceramic is selected to match the antenna to its operating frequency, which may be in the range of 0. 5 to 10. 0 Gigahertz. A process for making such antennas is also disclosed. The antenna may be used in portable terminals and other devices requiring small, durable and inexpensive antennae.
