Title: Innovations of Mathias Boettcher in Semiconductor Technology.
Introduction
Mathias Boettcher is a notable inventor based in Dresden, Germany. He has made significant contributions to the field of semiconductor technology, holding a total of 4 patents. His work focuses on enhancing the efficiency and reliability of solder bump structures used in electronic devices.
Latest Patents
Among his latest patents, one is titled "Solder bump structure and a method of forming the same." This invention discloses a solder bump structure where a first and a second metal film are deposited over a contact pad. The second metal film is patterned before the deposition of solder bump material, creating an opening that isolates an inner region from an outer region. The solder material deposited on the inner region serves as an etch stop for the removal of the outer region.
Another significant patent is "Bump scrub after plating." This patent describes a method for forming uniform bumps on a semiconductor device. A mask is applied to the device's surface, with openings corresponding to the electrical contact pads. Solder or conductive material is deposited until each opening is filled. The mask and solder balls are then scrubbed to achieve a uniform height and volume across the wafer. The process concludes with the removal of the mask and reflowing the solder to form uniform solder balls or bumps.
