Title: Argon/ammonia rapid thermal annealing for silicon wafers, silicon wafers fabricated thereby and Czochralski pullers for manufacturing monocrystalline silicon ingots
Inventor: PARK JAE-GUN
IPC: C30B15/14
Filed: 2001-12-27
Granted: 2002-12-11
Abstract: A silicon wafer is provided having controlled distribution of defects, in which denuded zones having a sufficient depth inward from the surface of the wafer are combined with a high gettering effect in a bulk region of the wafer. In the silicon wafer, oxygen precipitates, which act as intrinsic gettering sites, show vertical distribution. The oxygen precipitate concentration profile from the top to the bottom surfaces of the wafer includes first and second peaks at first and second predetermined depths from the top and bottom surfaces of the wafer, denuded zones between the top and bottom surfaces of the wafer and each of the first and second peaks, and a concave region between the first and second peaks, which corresponds to a bulk region of the wafer. For such an oxygen precipitate concentration profile, the wafer is exposed to a rapid thermal annealing process in a gas mixture atmosphere comprising ammonia (NH3) and argon (Ar) at temperatures below about 1200 DEG C. Using such a rapid thermal annealing process, slip dislocation can be reduced in the device regions of the wafer, and silicon dioxide sublimation on the rapid thermal annealing chamber also can be reduced.

Title: Generator of microscopic laser ultrasonic and inspection method thereof
Inventor: LI JU-YU
IPC: G01N29/04
Filed: 2001-12-31
Granted: 2002-11-01
Abstract: Non-destructive inspection method and generator of microscopic laser ultrasonic are invented to inspect surface and interior defects in micro scale. The whole system includes an ultrasonic wave generation module, a microscopic module and an ultrasonic wave detection module. The procedures of this method are as follows. Impulse and continuous lasers pass through the microscopic module and generates ultrasonic wave in the target. Due to the ultrasonic reflection, a test beam reflected from the target interfering with the continuous reference beam forms a phase grating in a birefringence material. The interference light is received by the photo detector and converted to voltage signal that is processed by a computer. The target defect position can be obtained by multiplying the ultrasonic wave speed and the time delay.

Title: IC chip and display device using such chip
Inventor: YAMAMURA KUNI
IPC: H01L29/786
Filed: 2002-03-01
Granted: 2003-08-11
Abstract: An IC chip has a substrate which is made of a glass substrate to reduce the manufacturing costs and failure rate of the display device in which the IC chip is used. If the substrate of the display device is also made of glass, the thermal expansion rate of the substrate will be the same as that of the IC chip, whereby the IC chip can be prevented from falling apart and the failure rate of the display device can be reduced. When the IC chip is used for the gate line driving IC7 for display device 1, the IC chip 7 may be made in the same length as the display region, and thus there is no need to mount a plurality of IC chips for use as a gate line driving IC, and the manufacturing costs can be reduced. Gate lines 9 can be extended all in parallel with each other from IC chips 7 respectively, so that the delay among the gate lines 9 will not happen and the margins can be narrowed.

A collaboration system connected to the Internet includes a collaboration server and multiple clients. A redirect program is resident in a client and monitors a URL transition event, and if a URL transition event has occurred, the redirect program captures the URL transition event and permits a browser to cancel it. Thereafter, the URL is redirected to the collaboration server. In response to the URL transition event, the collaboration server obtains contents from a web server. Applets for synchronization is added to the obtained contents, and the resultant contents are then transmitted to the client. Since contents are constantly obtained through the collaboration server, client collaboration is implemented.

Title: Heterojunction bipolar transistor
Inventor: WANG CHENG-HAU
IPC: H01L29/737
Filed: 2003-05-30
Granted: 2004-05-21
Abstract: The present invention relates to a heterojunction bipolar transistor, especially a bipolar transistor having double heterojunction, whose main structure comprises: a GaAs substrate, a collector layer, a delta-doped layer, a spacer, a base layer and an emitter layer. The base layer is made of InGaAsN material with narrow bandgap, and is has graded doping to gradually increase the doping from the collector toward the emitter (if the base is P-type), so that the potential curve of the conduction band in the base layer is tilted, the carriers can obtain higher kinetic energy when the carriers passes through the base. Thus the carrier can easily pass through the potential barrier at the heterojunction between the base and the collector. Also, a delta-doped layer and spacer can be added between the base layer and the emitter layer, which can increase the current gain effectively, reduce the power consumption and reduce the threshold voltage.

Abstract: In this invention, an extended gate ion sensitive field effect transistor (EGFET) was used to be an array pH sensor and its readout circuit. The multi-structures of this EGFET, which used to be an array pH sensor, are SnO2/A1/SiO2 gate EGFET and SnO2/ITO/glass gate EGFET, respectively. The characteristics of the EGFET have high performances such as a linear pH sensitivity of approximately 56 to 58 mV/pH in a concentration range between pH2 and pH10. Besides that, two clock signals were used to control the data of readout circuits and devices. Especially, the device of the array pH sensor has increased the resolution and decreased the noise. In addition, this invention has other advantages, such as the inexpensive fabrication system, low cost, and mass production characteristics. Based on the above characteristics, a disposal sensing device can be achieved. Thus, this invention has a high feasibility in array pH sensor.
