Patent number: 8106664Abstract: An apparatus for a user to conduct an accelerated soft error test (ASER) on a semiconductor sample is provided. The apparatus comprises a first component for holding the radiation source, where the radiation source may be either an alpha-particle or neutron-particle source. The apparatus comprises a second component for holding the semiconductor sample, where the semiconductor sample may be either a silicon wafer or semiconductor chip. The apparatus comprises a connecting assembly for placing the first component and the second component relative to each other at a plurality of positions that subject the semiconductor sample to a radiation stress from the radiation source at a plurality of stress efficiencies. Among the benefits provided are improved repeatability and credibility of ASER tests and reduced radiation exposures to operators of ASER tests.Type: GrantFiled: August 25, 2008Date of Patent: January 31, 2012Assignee: Semiconductor Manufacturing International (Shanghai) CorporationInventors: Jung-Che Chang, Wei-Ting Chien

Publication number: 20110068909Abstract: A battery-free remote controller includes an antenna, a plurality of key switches, and at least one electronic tag. The antenna is electrically connected to the plurality of key switches, and each electronic tag is electrically connected to the antenna through at least one of the key switches. Each electronic tag is corresponding to a device classification code, and each key switch is corresponding to an operation code. When one of the key switches is turned on, the electronic tag connected to the key switch is electrically connected to the antenna. At this time, the electronic tag uses a radio frequency signal received by the antenna as a power supply to output a remote control code containing the device classification code corresponding to the electronic tag and the operation code corresponding to the key switch, and the antenna transmits the remote control code.Type: ApplicationFiled: September 24, 2009Publication date: March 24, 2011Inventor: Jung Che Chang

Patent number: 7423651Abstract: The present invention provides a single-chip but multi-output graphic system which provides identical or different graphic images on two display screens. The graphic system comprises at least a multimedia database, a first input process router, a second input process router, a first graphic processing unit and a second graphic processing unit. The first input process router selects the backdrop graphics and the moving object graphics (which are both provided by the multimedia database), feeds them into the first graphic processing unit and then outputs the processed graphics onto either the first display unit or the second display unit. Similarly, the second graphic processing units processes the backdrop graphics and the moving object graphics selected by the second input process router and then outputs the process graphics onto either the first display unit or the second display unit.Type: GrantFiled: October 13, 2005Date of Patent: September 9, 2008Assignee: V. R. Technology Co., Ltd.Inventors: Jung-Che Chang, Tai-Cheng Wang

Patent number: 6441766Abstract: A charge integration algorithmic analog-to-digital converter utilizes one operational amplifier to perform an algorithm analog-to-digital conversation. In a first operating cycle, the ratio of a third capacitor to a fourth capacitor is used as a gain to determine an output voltage and an output bit. The output voltage is held in a first and second capacitors. In the second operating cycle, the ratio of the first capacitor to the second capacitor is used to determine an output voltage and an output bit. The output voltage is held in the third and fourth capacitors. The first and second operating cycles are repeated for generating converted digital data.Type: GrantFiled: November 22, 2000Date of Patent: August 27, 2002Assignee: Sunplus Technology Co., Ltd.Inventors: Chao-Kuei Chuang, Jung Che Chang
