Electroplating-based flip chip solder preparation process had been widely used over other preparation methods. Although it is cheaper and is able to achieve the material deposition on the fine pitch I/O pads, the solder bumps resulted are not uniform and not quality-guaranteed. In this invention, ma.....

Antibodies are proteins produced by the body!|s immune system in response to foreign elements (antigens) which invade the body. Antigenized antibodies are antibodies which are genetically engineered in their variable domain to express epitopes of different antigens. As such, antigenized antibodies c.....

At present time techniques in preparing advanced ceramic materials with high electrical conductivity and magnetic susceptibility are rare. This new invention relates to hyperbranched organometallic polymers, which are useful as precursors to certain ceramic materials, processes for the preparation o.....

Liquid Crystal Display (LCD) TV is a big potential market. However, the response time of the LCD TV is still inferior to PDP; fuzzy edge on moving objects is observed in the LCD TV. To make fast switching, wide viewing angle and optical efficient LCD, pi-cell is a possible choice.In this invention, .....

A thin film transistor (TFT) is an insulated-gate field effect transistor that is fabricated using thin film techniques on an insulating substrate rather than a semiconductor. Integrated circuits (IC) built using polysilicon thin film transistors at low temperatures have attracted much attention in .....
