Title: Wafer Scale Integration of Mid-wavelength Infrared Imagers

Abstract:

High performance infrared focal plane arrays (FPAs) play a critical role in a wide range of imaging applications. However the high cost associated with the required cooling and serially processed die-level hybridization is major barrier that has thwarted Mid-wavelength Infrared (MWIR) detector technology from penetrating large-volume, low-cost markets. Under the DARPA WIRED program, the HRL team has investigated several wafer level integration schemes to fabricate Antimonide-based MWIR detectors on Si Read Out Integrated Circuit (ROIC) as a means to achieve significant fab cost reduction and enhanced production scalability. The DARPA-hard challenge we are addressing is the thermal and stress management in the integration of two dissimilar materials to avoid detector and ROIC degradation and to maintain structure integrity at the wafer scale. A combination of heterogeneous epitaxial growth and micro-fabrication techniques was investigated to explore the most viable integration scheme, resulting in a successful demonstration of first wafer scale III-V MWIR FPA. In this talk, we will give a quick introduction to infrared detection and imaging technologies, and discuss our progress under the DARPA WIRED program.

Bio:

Minh Nguyen is a Senior Research Scientist in the Sensors and Electronics Laboratory at HRL Laboratories. Prior to joining HRL in 2014, he received his PhD in Electrical Engineering from Northwestern University and held positions in diverse research environment such as Research Assistant Professor at Northwestern University, technical director of a small business, director’s postdoctoral fellow at Los Alamos National Lab. Nguyen has over 14 years of experience in developing and managing multiples research projects on Antimonide–based materials for infrared detection and topological quantum computation. His expertise encompasses the areas of device modeling/design, epitaxial growth, device fabrication and testing. He is also involved in nanoscale epitaxy and nanofabrication of III-V and Ge/Si semiconductors for applications including solar cells, field effect transistors and quantum computation. Nguyen has authored/co-authored six book chapters, more than 80 technical papers with over 3000 citations and an h-index of 33.
