Title: Sensorless three-phase brushless DC motor drive circuit
Inventor: LEE YOUNG-KYU
IPC: H02P6/182
Filed: 1998-08-25
Granted: 2001-02-21
Abstract: A drive circuit for a sensorless three-phase brushless DC motor provides improved drive characteristics by detecting voltages changes in the stator coils, and then comparing the voltage changes to a timing diagram of the back-electromotive signal to commutate the current through the stator coils before maximums in the back-electromotive force, thereby providing smoother motor rotation. The drive circuit includes comparators for generating rectangular difference signals by comparing the voltage of the stator coils, and edge detector and control circuit for generating a pulse signal that is delayed from the difference signals, signal generators for generating a trapezoidal signal and three step signals responsive to the pulse signal, and an output control circuit for generating drive signals for a commutator drive circuit responsive to the trapezoidal step signals. By setting the voltage differences between the trapezoidal and step signals to values less than the Hall bias level the drive signals can be made to change linearly, thereby providing soft switching of the transistor switches in tile commutator drive circuit.

Title: Method for preventing crack generation of inter-metal dielectric layer in integrated circuit
Inventor: CHEN JIN-TSAI
IPC: H01L21/76
Filed: 1999-09-30
Granted: 2002-08-01
Abstract: A method for preventing crack generation of inter-metal dielectric layer in integrated circuit is proposed in the present invention. At first, a lower layer of metal conduction wire is formed on a semiconductor substrate, in which the front-end process has been completed on the semiconductor substrate. After that, the first dielectric layer, the second dielectric layer, and the third dielectric layer are continuously deposited to form an inter-metal dielectric layer. The third dielectric layer is a silicon oxide layer and is formed by using PECVD (plasma enhanced chemical vapor-phase deposition) method through the use of TEOS as the main reaction gas. When forming the third dielectric layer, it is necessary to adjust the power values of both high power and low power plasma generators so as to make the third dielectric layer have larger compressive stress, which is within the range of -3 to -2.0E9 dyne/cm<SP>2</SP>. Therefore, the substrate is made to exhibit a bending-downward strain for preventing crack generation.

Granted: 2002-07-11
Abstract: A USG layer 26 is formed to cover an aluminum wiring 24 deposited a field oxide film 22. An organic SOG layer 28 whose thick layer can be easily formed is formed in a groove on the surface of the USG layer 26. Thus, the unevenness of the surface of the USG layer 26 can be relaxed in a degree. Further, an USG layer 30 is formed thereon is formed through the vapor phase growth technique using the high density plasma which can realize excellent embedding. Accordingly, the inter-metal dielectric film 32 having a flat upper surface can be formed. Further, the SOG step is carried out only once in the step of forming the organic SOG layer 28, thereby reducing the production cost. Further, since the organic SOG layer 28 can be encircled by the USG layers 26 and 39 having good film quality, even if the material of the organic SOG layer 28 is not so good, the inter-metal dielectric film 32 with an excellent dielectric property can be formed. Thus, a method for manufacturing a semiconductor device which can form the dielectric film having excellent dielectric property and an upper flat surface at low production cost and in a short lead time.
