NHanced Semiconductors proposes to design, fabricate, assemble and test an 8k x 8k delta doped 3D Advanced Hybrid Detector (AHD) prototype targeted for the deep to near UV spectrum (90nm – 400nm). The detector prototype will contain sixty-four 1024x1024 pixel 268.4mm23D AHD chiplets, tiled on a 200mm interposer wafer in an 8x8 array.We intend to leverage our design experience and our state of the art integration technologies (Direct Bond Interconnect - DBI® technology and die-to-wafer transfer printing technology)to perform intimate sensor to ROIC 3D integration for the detector chiplets and then 2.5D die-to-wafer tiling on a silicon circuit card. Our technologies will allowimproved granularity, reliability, noise, speed and power performance. All, extremely relevant features for NASA.The Phase I development sets the ground work to ensure a successful Phase II outcome as well as helping to ensure the targeted device does in fact fulfill a desirable application. The Phase I results, high level designs, design simulation validation and complete specifications, are vital to guaranteeing the final form, fit and functionality.
Our planned AHD device is relevant to NASA for both the Large UV Optical Infrared (LUVOIR) Surveyor program and the Habitable Exoplanet (HabEX) program which are both intended for launched in the mid/late 2030s. Beyond these two identified potential program uses, the results of Phase II are applicable to sensors across the entire EM spectrum and the technology can easily to adopted and exploited for x-ray, gamma-ray or any optical light sensor which could further benefit LUVOIR as well as the High-Definition X-Ray imager in the LYNX program.
Commercial uses of a high performance UV imager include fine scratch detection and organic contamination detection. There are potential market uses of the imager for forensic analysis. Previous publish work has shown the usefulness of identifying unreported automotive body repairs. While to the human eye these repairs look perfect, in UV light wavelengths, inherent material differences stand out.
