Publication number: 20240153843Abstract: A package structure is provided. The package structure includes a semiconductor die and a thermoelectric structure disposed on the semiconductor die. The thermoelectric structure includes P-type semiconductor blocks, N-type semiconductor blocks and metal pads. The P-type semiconductor blocks and the N-type semiconductor blocks are arranged in alternation with the metal pads connecting the P-type semiconductor blocks and the N-type semiconductor blocks. When a current flowing through one of the N-type semiconductor block, one of the metal pad, and one of the P-type semiconductor block in order, the metal pad between the N-type semiconductor block and the P-type semiconductor block forms a cold junction which absorbs heat generated by the semiconductor die.Type: ApplicationFiled: January 17, 2024Publication date: May 9, 2024Applicant: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Cheng-Yen Hsieh, Chih-Horng Chang, Chung-Yu Lu

Patent number: 8812806Abstract: Method and system for migrating a virtual storage system from a source storage system having access to a source storage device to a destination storage system having access to a destination storage device is provided. A processor executable management application estimates a likelihood of success for a migration operation before the migration operation enters a cut-over duration during which client access to the source storage system and the destination storage system is restricted. The migration operation enters the cut-over duration if there is high likelihood of success for completing the migration during the cut-over duration or aborted, if there is a low likelihood of success for completing the migration during the cut-over duration.Type: GrantFiled: October 29, 2010Date of Patent: August 19, 2014Assignee: Netapp, Inc.Inventors: John Fredricksen, Chung-Yen Chang, Nagender Somavarapu

Patent number: 7259084Abstract: This invention provides a process for growing Ge epitaxial layers on Si substrate by using ultra-high vacuum chemical vapor deposition (UHVCVD), and subsequently growing a GaAs layer on Ge film of the surface of said Ge epitaxial layers by using metal organic chemical vapor deposition (MOCVD). The process comprises steps of, firstly, pre-cleaning a silicon wafer in a standard cleaning procedure, dipping it with HF solution and prebaking to remove its native oxide layer. Then, growing a high Ge-composition epitaxial layer, such as Si0.1Ge0.9 in a thickness of 0.8 ?m on said Si substrate by using ultra-high vacuum chemical vapor deposition under certain conditions. Thus, many dislocations are generated and located near the interface and in the low of part of Si01.Ge0.9 due to the large mismatch between this layer and Si substrate. Furthermore, a subsequent 0.8 ?m Si0.05Ge0.95 layer, and/or optionally a further 0.8 ?m Si0.02Ge0.98 layer, are grown.Type: GrantFiled: November 4, 2003Date of Patent: August 21, 2007Assignee: National Chiao-Tung UniversityInventors: Edward Y.

Patent number: 5831376Abstract: An electro magnetic controlled platinum infrared filament ignitor has a screw nut, a top pin, an electro magnetic induction coil, a magnetic permeable bolt, a metal wrapped cylinder and a platinum filament. Heat produced by current flowing in the platinum filament actuates the ignitor. The magnetic force set up by the energized coil, and spring force drives the adjustable top pin to the position of the platinum filament. The ignitor is simple in construction with endurable long life and efficient for ignition in most gas turbines, reciprocating engines and gas burners.Type: GrantFiled: November 1, 1996Date of Patent: November 3, 1998Assignee: Industrial Technology Research InstituteInventors: Wu-Chi Ho, Chii Ron Kuo, Bor Rong Jong, Tseng Wuu Wey, Chung Yen Chang
