Almost all circuit systems require a voltage reference. A voltage reference provides a temperature and supply independent voltage. In addition, this voltage reference mudt be able to operate under low-voltage low-power conditions and can be implemented in standard CMOS process instead of expensive B.....

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.....

Conventional graphite made from sulfuric acid-graphite intercalation compound (GIC) contains much amount of sulfur, which cause environmental pollution and corrosion.The invention provides a new formic acid-GIC synthesized by an electrochemical process in which formic acid is used as electrolyte. Th.....
