摘要:
A micro-fabricated device (100, 300, 400, 500), includes a support structure (140, 240, 340, 440, 540) having an aperture (142, 242, 342, 442, 542) formed therein, and a device substrate (130, 230, 330, 430, 530) disposed within the aperture. The micro-fabricated device further includes a thermally isolating structure (120, 220, 320, 420, 520) thermally coupling the device substrate to the support structure. The thermally isolating structure includes at least one n-doped region (152, 252, 352, 452, 452') and at least one p-doped region (154, 254, 354, 454, 454') formed on or in the thermally isolating structure and separated from each other. In addition, the thermally isolating structure includes an electrical interconnect (156, 256, 356, 456) connecting at least one n-doped region and at least one p-doped region, forming an integrated thermoelectric device.
摘要:
The invention relates to a thermoelectric element comprising at least one n-type layer (1) and at least one p-type layer (2) of one or more doped semiconductors, whereby the n-type layer(s) (1) and the p-type layers(s) (2) are arranged to form at least one pn-type junction (3). At least one n-type layer (1) and at least one p-type layer (2) are contacted in an electrically selective manner, and a temperature gradient (T1, T2) is applied or tapped parallel (x-direction) to the boundary layer (3) between at least one n-type layer (1) and p-type layer (2). At least one pn-type junction is formed essentially along the entire, preferably longest, extension of the n-type layer(s) (1) and of the p-type layer(s) (2) and thus essentially along the entire boundary layer (3) thereof.

A method and structure for heat transport, cooling, sensing and power generation is described. A photonic bandgap structure ( 3 ) is employed to enhance emissive heat transport from heat sources such as integrated circuits ( 2 ) to heat spreaders ( 4 ). The photonic bandgap structure ( 3 ) is also employed to convert heat to electric power by enhanced emission absorption and to cool and sense radiation, such as infra-red radiation. These concepts may be applied to both heat loss and heat absorption, and may be applied to heat transport and absorption enhancement in a single device.

Connection of the leads for a thermoelectric module is readily accomplished, and after connection, the tensile strength of the connection is enhanced. One ends of the front and back side lead patterns for the thermoelectric module 16A and 16B , formed on a support plate 1, are connected by solder 24 to a Cu rod 2C provided at an end of a group of thermoelectric semiconductor elements affixed to the support plate 1 . After the front end of the lead for the thermoelectric module 22A is bent and passed from the side of the front lead pattern 16A through a through hole formed between the front and back side lead patterns 16A and 16B, the front end is connected to the back side lead pattern 16B by solder 25.

A package (10, 60, 80) has a chamber (24) containing an integrated circuit (13) which detects infrared radiation. The package has on one side of the integrated circuit a portion (23) transparent to infrared radiation, and has on the opposite side of the integrated circuit a first part (12) which supports the integrated circuit. A second part (36) of the package is spaced from the first part (12) on the side thereof opposite from the integrated circuit. Thermoelectric cooling elements (51) are provided between and are thermally coupled to the first and second parts. Electrically conductive further elements (44) are also disposed between the first and second parts. A first arrangement (32, 29, 17, 18) electrically couples a terminal on the integrated circuit to a first end of the further element. A second arrangement (41, 38) electrically couples each further element to a respective pad (42) disposed on the side of the second part opposite from the first part. Some of the thermoelectric cooling elements may have one cross-sectional shape, others may have a different cross-sectional shape, and the further elements may have still another cross-sectional shape.

An apparatus and method of manufacturing a thermoelectric module is provided. A first electrically conductive pattern (22) is defined on a first substrate (20) and a second electrically conductive pattern (23) is defined on a second substrate (21). Alternating bars (54, 55) of a first thermoelectric material and a second thermoelectric material are arranged parallel to each other. The bars are fixed into place on the first conductive pattern by an effective thermal and electrical connection with the conductive pattern. One such connection means is soldering. Then the bars are separated into elements (64, 65). The second substrate is positioned over the elements and fixed to the elements to complete the manufacture of the TEM.
