Title: Synthetic Combinatory Bendable Substrates (CyCoBs) for Ultra-lightweight, Structurally Embedded Infrared (IR) Camera

Abstract:

This SBIR effort will show feasibility of very thin, lightweight, integrated FPAs on a novel, flexible substrate which can double as the IR transmissive window and be readily transferred onto curved or conformal surfaces, or structural elements of a Micro-Air Vehicle (MAV). Versatilis will build and demonstrate a simple such (2x2) IR detector array using a ternary lead salt (PbCdSe) from BAE Systems. The technology will enable very lightweight IR cameras ~10g for MAVs for long endurance and higher power payloads (>90 mW-hr). Versatilis has developed a synthetic crystalline substrate material which can be used in such applications, branded "Versulite," combined with a process for growing heteroepitaxial single crystal thin films atop it. Versulite is an extremely rugged, stable insulating material, fully transparent to visible and SWIR-NIR with a very high melting point (>>1000 degrees C) compatible with Silicon processes, and lattice constants close to Silicon for epitaxy. A lamellar crystal, it can be cleaved into easily transferable, thin, flexible sheets. Package weight should result in an order of magnitude reduction in weight for the FPAs from ~25-50 g (current state-of-the-art). Adoption of such a compliant, flexible, substrate material can ultimately allow for fully integrated FPAs with much of the ROIC circuitry built onto the detector substrate itself, eliminating a whole series of interconnect issues, and decreasing mass and cost while increasing inherent reliability, with broad application in military and commercial applications. Silicon epitaxy on Versulite, in particular, can be an intriguing SOI technology for applications well beyond IR detectors, enabling integrated, flexible electronics for a variety of other applications.
