Title: Method of automatic electrode wear compensation in equal depth pore electro-discharge machining
Inventor: SHR JIAU-JING
IPC: B23H7/20
Filed: 2001-04-12
Granted: 2003-02-11
Abstract: This invention provides a method of automatic electrode wear compensation in equal depth pore electro-discharge machining. In setting the machining depth value D of a pore electro-discharge machine, the machining depth value D is computed as the sum of the machining depth Z of a workpiece, an electrode wear rate W and a correction value (offset), and a machining electrode performs pore electro-discharge machining to the actual workpiece on the basis of the numeric value and a machining program. In order to set the wear rate W of the pore machining electrode to the moving state value of automatic measuring calculation, the Z-axis value of the machining electrode to the workpiece surface measured in first pore machining is made the reference value, and the Z-axis value of the electrode to the workpiece surface in second pore machining is reduced, that is, the actual electrode wear value in preceding pore machining is measured, and the measured electrode wear value can be input as the electrode wear value in the following pore machining. As such, this invention can minimize an error, shorten a process per machining and effectively improve work efficiency.

Title: Planarization method for bottom anti-reflective layer during dual damascene process
Inventor: CHEN ANSEIME
IPC: H01L21/768
Filed: 2001-05-02
Granted: 2002-11-01
Abstract: A planarization method for bottom anti-reflective layer during dual damascene process is provided to obtain smoother bottom anti-reflective coating layer by chemical mechanical polishing of the bottom anti-reflective coating to form dual damascene interconnect structure. The coated bottom anti-reflective coating layer is first heated at low temperature before the bottom anti-reflective coating material is crosslinked to acquire anti-reflective character. The bottom anti-reflective coating is then planarized by chemical mechanical polishing. Before being coated with photoresist, the bottom anti-reflective coating layer is heated at high temperature. Thus, the surface roughness of the bottom anti-reflective coating is reduced to a minimum and the bottom anti-reflective coating layer possesses anti-reflective character. Therefore, distortion of via hole profiles and control of critical dimension of via holes are improved due to transferring via hole patterns to a smoother anti-reflective surface.

Title: Leadframe with a function of controlling the collapse quantity and flip-chip semiconductor package having the leadframe
Inventor: WU JI-CHIUAN
IPC: H01L23/28
Filed: 2001-08-22
Granted: 2002-08-11
Abstract: There is provided a flip-chip semiconductor package having a leadframe capable of controlling the reflow collapse degree of the solder bump. The leadframe is composed of a die pad and a plurality of leads and the height of the die pad must be larger than the thickness of the leads so as to form a height difference. However, the height difference can not be larger than the vertical height of a plurality of solder bumps in flip-chip bonding. Because the excellent wetability of the leadframe in performing reflow will make the solder bumps of alloy with a low melting point continuously collapse, the semiconductor chip originally depending on the solder bumps to stand on the die pad will gradually move down. At this moment, the die pad with a larger height will block the movement of the die, so as to force the solder bump to stop collapsing and maintain at a constant height, thereby preventing solder bumps from generating brittleness due to over-collapse which may influence its soldering quality.

Title: Clustered creature exterminating method
Inventor: KARASAWA YUKIHIKO
IPC: C02F1/34
Filed: 2001-09-21
Granted: 2006-06-01
Abstract: A clustered creature exterminating method exterminating clustered creature such as cyanobacteria in large quantity. The clustered creature exterminating method of the present invention comprises the steps of: pressurizing a fluid containing a clustered creature such as cyanobacteria through a pump; suddenly lowering the pressure applied to the fluid by injecting the fluid from nozzle groups 2a, 2b; and destroying a bonding in the clustered creature by a cavitation caused by the pressure drop. The nozzle groups 2a, 2b may be arranged so as to oppose with each other to collide the injected fluids with each other, which allows the cyanobacteria to be divided into many small pieces. As a result, the cyanobacteria lose the capacity to rise and sink at the bottom of water, therefore, they cannot photosynthesize to die out.

Title: Three-phase shunt type active power filter capable of operating in parallel
Inventor: JIANG SHIUAN-JANG
IPC: H02G1/08
Filed: 2001-10-16
Granted: 2003-08-21
Abstract: Compared with other types of active power filters, the shunt type active power filter requires to process a larger portion of load power. Therefore, if the filter is implemented by high frequency switching type switches, the capacity of the filter is limited by the voltage and current capable of being reached by the switches. To overcome such a problem, the present invention provides a control method capable of limiting the output capacity of the active power filter, and a method for sensing the serial load current, so that the filter is formed by multiple sets connected in parallel without having a control signal connection, thereby increasing the system capacity and increase the reliability. The inventive filter is suitable for three-phase three-wire and three-phase four-wire systems, and can compensate the virtual power of the load, and non-balance of harmonic current and three-phase current, thereby making the input current to be a low-distorted waveform having a phase same as the voltage, and the current of neutral line (three-phase four-wire system) to be zero. In addition, the present invention also provides: (1) a PWM switching method of three-phase four-wire converter to decouple the switching of the switch of each arm to reduce the complexity of the controller; (2) a circuit architecture using a small capacitor serially connected to the neutral line of the input power so as to remove the high-frequency switching current harmonic waves on the neutral line thereby preventing conductive EMI.
