8/266396

Inventors:

Michael W. Goodwin - Garland TX

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

H01L 310296
H01L 3109

US Classification:

2503384

Abstract:

A HgCdTe S-I-S (semiconductor-insulator-semiconductor) two color infrared detector wherein the semiconductor regions are group II-VI, preferably HgCdTe, with different compositions for the desired spectral regions. The device is operated as a simple integrating MIS device with respect to one semiconductor. The structure can be grown by current MBE techniques and does not require any significant additional steps with regard to fabrication.

Appl. No.:

8/305639

Inventors:

Michael W. Goodwin - Richardson TX

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

H01L 2714
H01L 3100

US Classification:

257440

Abstract:

A two-color infrared detector (50) is provided comprising elements (10, 110, or 210) having one or more diodes (58, 158 and 168) and a metal insulator semiconductor ("MIS") device (56 and 156). The infrared detector (50) may be referred to as a vertically integrated capacitor diode. The diodes comprise regions (12, 14, 16, 112, 114, and 116) of semiconductor materials which are operable to generate electron-hole pairs when struck by infrared radiation (40) having first and second wavelengths. The capacitor (156) includes a gate (24) provided by the MIS device which is operable to generate a potential well in the first semiconductor region (12 and 112) in conjunction with an insulator layer (22) and collect charges generated by the first wavelength of infrared radiation (40). The layers of semiconductor material may be varied to enhance the performance of the resulting infrared detector.

F16L 25/14

Abstract:

A method of sealing the interstice in double-walled pipe includes the steps of applying a first sealing piece to an inner pipe of the double-walled pipe, wherein the first sealing piece covers a portion of the circumference of the inner pipe; and applying a second sealing piece to the inner pipe of the double-walled pipe, wherein the second sealing piece covers the remainder of the circumference of the inner pipe. The method further includes the step of attaching the first sealing piece to the second sealing piece forming a sealer; wherein the sealer is disposed in an annular space located between the inner pipe and an outer pipe. A sealer configured to seal an opening between pipes in a double-walled pipe includes a first sealing piece having a rounded cross-section with an attachment portion configured to engage a corresponding attachment portion disposed on a second sealing piece.
