Recent advances in miniaturization of IR imaging technology have led to a growing market for mini thermal-imaging sensors. In that respect, Sofradir development on smaller pixel pitch has made much more compact products available to the users. When this competitive advantage is mixed with smaller coolers, made possible by HOT technology, we achieved valuable reductions in the size, weight and power of the overall package. At the same time, we are moving towards a global offer based on digital interfaces that provides our customers simplifications at the IR system design process while freeing up more space. This paper discusses recent developments on hot and small pixel pitch technologies as well as efforts made on compact packaging solution developed by SOFRADIR in collaboration with CEA-LETI.

In deep submicron CMOS and BiCMOS technologies, antenna effects affect the floating gate charge of conventional floating gate test structures, dedicated to capacitor matching measurement. In this paper, a new pseudo-floating gate test structure is designed. After test structure and modeling presentation, the testing method and results are given for several capacitor layouts (poly-poly and metal-metal).
