Griego has filed for patents to protect the following inventions. Influence of Hot Rolling Temperature on Microstructural Evolution and Mechanical Properties of PM Copper Strip. This paper presents a numerical and experimental study of shape evolution of electrodeposition front on the extent of over-plating. This model demonstrates the impact of convection and diffusion on the transport-limited electrodeposition of a copper microconnector bump (metal post). The Metal Micromachining Program maintains three fabrication labs dedicated to process development. Processes or apparatus adapted for the manufacture or treatment of semiconductor or solid state devices or of parts thereof ({testing or measuring during manufacture or treatment, or reliability measurements H01L 22/00; multistep manufacturing processes for passive two-terminal components without a potential-jump or surface barrier for integrated circuits H01L 28/00; } processes or apparatus. It seems strange to call a raised bump a pit , but that is because when the discs are pressed, the stamper works from the top side.

This is the typical function of a power supply in an electronic device such as a computer or battery charger.
