  • Publication number: 20050212641
    Abstract: An inductor formed on a substrate having a dielectric layer thereon is disclosed. The inductor includes a first inductor pattern, a second inductor pattern a third inductor pattern. The first inductor pattern is formed within the dielectric layer, the second inductor pattern is formed on the first inductor pattern and electrically connected thereto, and the third inductor pattern is formed on the second inductor pattern and electrically connected thereto, wherein the first inductor pattern, the second inductor pattern, and the third inductor pattern have similar pattern. Because the thickness of the inductor can be increased by forming a multi-layer inductor structure, the resistance of the inductor, therefore, is reduced.

  • Patent number: 6934900
    Abstract: A test pattern generation and comparison circuit creates test pattern stimulus signals for and evaluates response signals from logic or memory such as random access memory (RAM). It utilizes both parallel and serial interfaces to the logic/memory under test. The test pattern generation and comparison circuit further provides a method for testing logic and memory utilizing built-in self test (BIST) techniques. The method uses a programmable logic/memory commands which are translated into physical logic signals and timings for the logic or memory under test. The results of the test pattern generated and applied to the logic or memory are compared to expected results. The result of the comparison is a pass/fail designation. In addition, the comparison of the expected test results with the actual test results provides information on the exact location of the failure.

  • Publication number: 20050110044
    Abstract: A fabrication method for heterojunction bipolar transistor is disclosed. The method uses ISSG oxide instead of conventional PECVD oxide so that the base/emitter interface damage can be reduced. Moreover, the invention replaces the conventional emitter-window/space mask with an emitter-window reverse-tone mask/line mask to minimize the critical dimension of emitter window. Furthermore, the invention also utilizes a two-steps extrinsic base implantation to form two extrinsic bases with different dopant concentrations so that the base resistance can be reduced.

  • Publication number: 20050101115
    Abstract: A method for forming a SiGe HBT, which combines a SEG and Non-SEG growth, is disclosed. The SiGe base layer is deposited by a Non-SEG method. Then, the first-emitter layer is developed directly upon the SiGe base layer that has a good interface quality between the base-emitter. Next, a second poly silicon layer, which has a dopant concentration range within 1E19 to 1E21 (atom/cc), is deposited by SEG method. It not only reduces the resistance of the SiGe base layer, but also avoids the annealing that may influence the performance of the device.

  • Patent number: 6722209
    Abstract: A Coriolis force type flow meter uses an optical interferometer as the measuring device. When a tube that a fluid flows through experiences a bending vibration caused by an external stimulating source, the tube also has a twist vibration due to the action of the Coriolis force. The optical interferometer is then employed to measure the tiny angular change in the amplitude of the tube vibration. From such a measurement, one can determine the flux of the fluid in the tube.
