Latest Patents
One of Smith's latest patents is focused on a wafer integrated rigid support ring. This innovative shadow mask for depositing solder bumps includes additional dummy holes located adjacent to holes corresponding to most of the perimeter chips of the wafer. The inclusion of these additional dummy holes provides more uniform plasma etching of contacts on the wafer, improves the etching of contacts on perimeter chips, and lowers the contact resistance of these contacts. Furthermore, the extra holes allow for solder bumps outside the perimeter chips, which can be utilized to support a second shadow mask for the deposition of additional materials, such as tin, on the reflowed solder bumps. This advancement facilitates the mounting of chips on a plastic substrate at low temperatures. Additionally, an improved mask-to-wafer alignment aid is formed from standard solder bumps, which helps avoid damage to test probes and provides improved course alignment.
