Latest Patents
McIntosh holds a patent for "Rapid prototyping of single-photon-sensitive silicon avalanche photodiodes." This patent describes 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 development schedule. Additionally, the 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 integration of fast microlenses directly on the APD back surface further enhances the performance of these devices, yielding APDs with low dark count rates (DCRs) and higher radiation tolerance for harsh environments.
