  • Patent number: 10487411
    Abstract: A method for synchronous electroplating filling of differential vias and an electroplating device. Laser irradiation is adopted as an external energy field to assist synchronous electroplating filling of differential vias. A mask or digital maskless technology is used to precisely heat the vias with different positions and different sizes. The filling rate of different regions varies with the temperature difference, thereby realizing the synchronous electroplating filling of differential vias in one step. In the processes of immersion pre-wetting by the electroplating liquid and electroplating filling copper, the laser is used for preheating the wafer processed with vias. In these two steps, the laser needs to locally and precisely heat upper surfaces of the micro vias on the wafer through the mask corresponding to the micro vias on the wafer.

  • Publication number: 20140284209
    Abstract: A portable hydrogen and oxygen supply system produces gaseous hydrogen and gaseous oxygen from water. It separates the gasses and vents them into two separate chambers. The supply system creates water disassociation through an array of concentric hexagonal hydrogen collector tubes, anode rods and a cathode matrix, all of which are submersed in water. The anode rods and cathode matrix are supplied DC electrical current. The water separates (disassociates) as atomic hydrogen is drawn to the negatively charged anode rods and the atomic oxygen is drawn to the positively charged cathode matrix. The hydrogen, on its path to the anode, passes through the walls of the hydrogen collector tubes to be collected in the first chamber. The oxygen is unable to pass through the walls of the tubes, and remains outside the tubes to be collected in the second chamber.

  • Publication number: 20140158529
    Abstract: The blue power generation system includes an electrolytic system to obtain hydrogen and oxygen from sea water. It also includes a power generating system to supply electrical energy to the electrolytic system and an installation to recombine hydrogen and oxygen to produce clean fresh water. More specifically, the deep-sea electrolytic reaction generate gases rising into reservoirs at sea level. As water is depleted in the electrolytic chamber, a low pressure is created in the electrolytic chamber. The pressure of makeup water required for the electrolytic reaction is used to drive a turbine and generate electrical power. A portion of the electrical power generated is used to drive the electrolytic reaction. The amount of electrical energy created is a direct relation with the depth at which the system is operated.
