Title: Single wire current share paralleling of current control mode DC power supplies
Inventor: CHEN CHIOU-LIN
IPC: H02J1/10
Filed: 1997-06-18
Granted: 2000-07-21
Abstract: This is a brand new method for controlling the paralleled modules current-sharing of a single wire current share paralleling of current control mode DC power supplies. The controlling method for every paralleled DC power supply is in current-controlling mode; therefore, a share bus will be used in-between the modules for current-sharing in order to share the exported current. By utilizing a method of single wire paralleled multiple modules with current-controlling, it is the simplest configuration. It will also enhance the response in circuit of power supply. Thus, it will decrease the possibility of uneven instant current condition and eliminate the unnecessary warning for limited-current. Moreover, the current feedback and current-sharing are sharing the same current detector. Therefore, this controlling method has a low production cost but also allows the power supply to become modularized completely. Thus, there lots of advantages such as improving the reliability and audio-susceptibility etc.

Title: Manufacturing method of a lead-containing galvanized steel sheet treated with chromate with excellent blackening resistance and white rust resistance
Inventor: MIYOSHI TATSUYA
IPC: C23C2/26
Filed: 1997-07-02
Granted: 2000-06-11
Abstract: This invention is about a manufacturing method of a lead-containing galvanized steel sheet treated with chromate with excellent blackening resistance and white rust resistance. The purpose of this invention is to produce shiny lead-containing galvanized steel sheet treated with chromate with good blackening resistance and white rust resistance without using pre-electroplate of Ni. The characteristic of this invention is to apply a lead-containing galvanized steel sheet with plating in a galvanizing bath having suitable concentration of Pb and Al to gain a shining and beautiful lead-containing galvanized steel sheet. Then, treat it with an alkaline aqueous solution of which the pH value is preferred to be above 9, and rinse with water. After that, it is coated with a chromate treating solution of which the molar ratio of the trivalent chromium ions/the sexivalent chromium ions is regulated between 1/9 and 1/1, and the molar ratio of the nitric acid ions to the total chromium ions is regulated between 0.1 and 1.6.  Without rinsing with water, it is dried at the specific plate temperature to form chromate coating with 5 to 50 mg/m<2> coating weight expressed in terms of metallic chromium. In this way, lead and aluminum concentrated at the galvanized surface can be effectively removed thus the blackening and white rust resistance of the lead-containing galvanized steel sheet can be improved.

Title: Method of using photoresist with cross-linking structure to prevent the passivation layer etching hole and photoresist extrusion
Inventor: CHEN SHR-SHIUNG
IPC: H01L21/30
Filed: 1998-05-01
Granted: 2001-10-11
Abstract: A method to prevent the passivation layer etching hole and photoresist extrusion is disclosed, which modifies the traditional positive photoresist used by the traditional passivation layer etching method into the negative photoresist which will generate linked structure after being exposed to light, so as to transfer the metal region pattern of the bonding pad and the test pad to be etched. The negative photoresist after the microlithography process has etching-resistant capability, even if it is a thinner photoresist layer, it is not easy to be consumed away in etching the passivation layer. So the function to prevent the passivation layer from being etched won't disappear due to the consumption of the photoresist layer at the thinner position and resulting in the hole of passivation layer in traditional technology. Therefore, to prevent the occurring of the hole of passivation layer, the planarization process of the passivation layer can be eliminated, and thereby to increase the reliability of the device and reduce the manufacturing cost. Furthermore, since the negative photoresist after developing has a robust linked structure, the photoresist flowing into the key hole won't be completely removed in the removal process of the photoresist, and the remaining photoresist won't be decomposed in the following alloy process and be extruded out of the passivation layer by the residual solvent evaporated at high temperature in the alloy process, so the integrity of the passivation layer won't be damaged. The method of the present invention comprises the following steps: deposit a passivation layer on the wafer after the post-metallization process is completed; form a negative photoresist layer on said passivation layer; proceed the microlithography process to define the pattern of said passivation layer; etch said passivation layer; and remove said photoresist layer.
