Title: Joseph Daniel Mis: Innovator in Microelectronic Technologies
Introduction
Joseph Daniel Mis is a notable inventor based in Cary, NC (US), recognized for his contributions to microelectronic technologies. With a total of six patents to his name, he has made significant advancements in the field of integrated redistribution routing conductors and solder bumps.
Latest Patents
One of his latest patents is titled "Methods for forming integrated redistribution routing conductors and solder bumps." This patent describes a method for forming routing conductors and solder bumps on a microelectronic substrate. The process involves creating an under bump metallurgy layer on the substrate and forming a solder structure on this layer. The solder structure consists of an elongate portion and an enlarged width portion. The method allows for selective removal of the under bump metallurgy layer not covered by the solder structure, using the solder structure as a mask. Additionally, the solder is designed to flow from the elongate portion to the enlarged width portion, forming a raised solder bump through heating above its liquidus temperature.
Another significant patent by Mis is "Key-shaped solder bumps and under bump metallurgy." This invention features a flip-chip structure that includes a semiconductor substrate with an electronic device, a contact pad, and a passivation layer. The passivation layer defines a contact hole that exposes a portion of the contact pad. An under-bump metallurgy structure is placed on the passivation layer, electrically contacting the exposed portion of the contact pad. The solder structure is positioned on the under-bump metallurgy structure, featuring both an elongate portion and an enlarged width portion.
