Title: Method for shallow trench isolation of transistors without using chemical-mechanical polishing
Inventor: WALSH SHAWN T
IPC: H01L21/318
Filed: 1999-03-12
Granted: 2001-03-21
Abstract: A method is given for removing excess oxide from active areas after shallow trench isolation, without the use of chemical-mechanical polishing. A nitride mask protects active areas during the etch of isolation trenches. The trenches are filled with oxide, using high density plasma deposition, which simultaneously etches, providing a sloping contour around the isolation trenches. A further layer of nitride is used to provide a cap over the trench which seals to the underlying layer of nitride. The cap layer of nitride receives a patterned etch to remove the cap only over the active areas. This allows a selective etch to remove the excess oxide, which can be followed by a selective etch to remove the nitride layers.

Title: Method and apparatus for reducing track misregistration due to digital-to-analog converter quantization noise
Inventor: LU WEI-MIN
IPC: G05B19/29
Filed: 2000-01-31
Granted: 2001-10-21
Abstract: A method and apparatus for reducing track misregistration due to digital-to-analog converter quantization noise. In hard disk drive (HDD) servo control systems, quantization noises (or roundoff errors) due to the finite precision of the D/A converter (DAC) driving the VCM contribute a significant portion of the total track-misregistration (TMR). The present invention provides a quantization error feedback (QEF) technique to reduce TMR due to DAC quantization noises. The QEF technique according to the present invention offers a simple method of reshaping the spectrum of this noise to minimize its contribution to TMR. In the digital signal processor (DSP) implementation of the QEF schemes, the quantization error is monitored and accumulated in the DSP; when sufficient error has accumulated, the MSB feeding the DAC are modified such as to cancel the effect of the error. In addition, or alternatively, a state estimator may be driven with the most significant bits and a position error signal to reduce the power spectrum density function of the track misregistration at predetermined frequencies.

Filed: 2000-02-15
Granted: 2001-07-01
Abstract: The temperature of a hot plate is not more than a predetermined threshold when a wafer is accurately mounted at a substrate mounting position on the hot plate, whereas the temperature of the hot plate is the predetermined threshold when the wafer is not accurately mounted at the substrate mounting position on the hot plate. Therefore, when the temperature of the hot plate is not less than the predetermined threshold when the wafer is mounted on the hot plate, it is judged that the wafer is stranded on a guide, and an alarm is given by means of a speaker or a display section.

Title: Printed circuit board with a multilayer integral thin-film metal resistor and method therefor
Inventor: LEE TIEN
IPC: H01C7/00
Filed: 2000-02-15
Granted: 2002-07-21
Abstract: A thin-film metal resistor (44) suitable for a multilayer printed circuit board (12), and a method for its fabrication. The resistor (44) generally has a multilayer construction, with the individual layers (34, 38) of the resistor (44) being self-aligned with each other so that a negative mutual inductance is produced that very nearly cancels out the self-inductance of each resistor layer (34, 38). As a result, the resistor (44) has a very low net parasitic inductance. In addition, the multilayer construction of the resistor (44) reduces the area of the circuit board (12) required to accommodate the resistor (44), and as a result reduces the problem of parasitic interactions with other circuit elements on other layers of the circuit board (12).
Patent TW-453066-B (TW)
Title: Method and apparatus for reliable and efficient data communications
Inventor: JOHANSSON MATHIAS
IPC: H04L12/56
Filed: 2000-02-22
Granted: 2001-09-01
Abstract: The present invention improves the reliability of data communication by analyzing plural data units in a group or a block rather than analyzing individual data units. For example, at the time that a transmitter desires or needs to send a polling request to a receiver, there may be more than one data unit available for delivery as a group. All of the polling fields of the data units in this group are set to indicate a poll request. When the receiver receives this group of data units, it sends the requested status information to the transmitter if the polling field of at least one of the received data units in the group indicates a poll request. Moreover, if the polling field of plural ones of the data units in the group indicates a polling request, the receiver sends the requested status information only once. Rather than not using the polling fields of the other data units in the group, which is effectively wasted bandwidth, the present invention employs those other polling fields to increase the reliability of the transmission. This improved reliability results in decreased transmission delay from the transmitter to the receiver. Further, the additional polling fields (or other additional fields) may be used to detect or otherwise correct errors that would otherwise be undetected or uncorrectable if only a single data unit were processed individually. The invention may be applied to other types of data unit fields.

Title: Vacuum switch for electricity
Inventor: KIMURA TOSHINORI
IPC: H01H33/664
Filed: 2000-06-01
Granted: 2001-10-01
Abstract: The present invention provides a kind of vacuum switch for electricity, in which, even an electric arc occurs at any position of the electrode contact surface, the switch can drive an electric arc through the use of a strong magnetism right after an electric arc occurs. The vacuum switch for electricity has the windmill-shaped electrode 1 that includes the followings: multiple windmill portions 4 on the central side, which are divided by multiple whirlpool-shaped grooves 2 from the central portion along the peripheral edge portion; and a contact portion 3 on the peripheral edge portion, which is divided by the groove 2 and has a wall thickness larger than that of the windmill portion 4. In addition, the electric arc, which occurs at the contact portion when current is cut-off, is driven by the magnetic flux generated by the current flowing in by passing through the windmill portion 4. In the magnetic flux density generated at this time, the composition of magnetic flux density parallel to the contact surface stated above is made to be larger than 0.01 Tesla per 1KA current for any position of the contact surface, in which the magnetic flux density is generated by the current that flows in the electric arc by passing through one side of the electrode of the windmill portion and becomes the driving force of electric arc for the range within a distance of 0.5 mm from the contact surface of electrode itself for the foot portion of electric arc. (Tesla is the unit of magnetic flux density, 1 Tesla=10<SP>4</SP> Gauss)
