Latest Patents

One of Volfson's latest patents is titled "Rapid prototyping of single-photon-sensitive silicon avalanche photodiodes." This invention introduces a chip-to-chip integration process for rapid prototyping of silicon avalanche photodiode (APD) arrays. The process offers several advantages over traditional wafer-level 3D integration, including reduced costs per development cycle, compatibility with previously fabricated read-out integrated circuits (ROICs), and an accelerated schedule. Additionally, this method allows for shorter processing times, as chips can be diced, bump-bonded, and thinned at the chip level more quickly than in wafer-level processes. The CMOS substrate provides mechanical support for the APD device, enabling the integration of fast microlenses directly on the APD's back surface. This innovation results in APDs with low dark count rates and higher radiation tolerance, making them suitable for harsh environments.

Another significant patent is the "Method for polishing micro-sized structures." This method involves identifying specific regions on a substrate for polishing, applying an adhesion promoter, and using a selected coating material that remains stable when exposed to an electrolyte. The process allows for the electropolishing of micro-sized structures while maintaining the integrity of the substrate.
