Heterogeneous integration of micro-opto-electromechanical systems (MOEMS) and integrated circuits (ICs) allows the combination of high-quality optical and photonic MOEMS materials such as monocrystalline silicon (Si) with standard CMOS-based electronic circuits in order to realize complex optical systems. In this paper, we will present examples of such heterogeneous optical systems, including CMOS-integrated...
We demonstrate infrared focal plane arrays utilizing monocrystalline silicon/silicon–germanium (Si/SiGe) quantum-well microbolometers that are heterogeneously integrated on top of CMOS-based electronic read-out integrated circuit substrates. The microbolometers are designed to detect light in the long wavelength infrared (LWIR) range from 8 to 14 μm and are arranged in focal plane arrays consisting...
This paper reports on the implementation and characterization of arrays of uncooled infrared bolometers containing mono-crystalline Si/SiGe quantum well (QW) thermistors. The bolometer arrays are integrated on silicon fan-out wafers using very-large scale heterogeneous integration that is compatible with standard CMOS wafers. Infrared bolometer arrays with 320×240 pixels and pixel pitches of 25 µm...
