Abstract
A sensor module includes a silicon substrate. A set of isolation walls defines, in the silicon substrate, an array of silicon-based image sensor pixels and an array of cavities. An infrared (IR)-sensitive material in the array of cavities forms an array of IR sensor pixels in a same focal plane as the array of silicon-based image sensor pixels.
Claims15
A sensor module, comprising:
- a silicon substrate;
- a set of isolation walls that defines, in the silicon substrate,
- an array of silicon-based image sensor pixels;
- and
- an array of cavities;
- and
- an infrared (IR)-sensitive material in the array of cavities and forming an array of IR sensor pixels in a same focal plane as the array of silicon-based image sensor pixels;
- wherein the IR-sensitive material comprises at least one of an organic material or a quantum film and an electrode is formed on the IR-sensitive material at an open end of each respective cavity of the array of cavities.

A sensor module, comprising:
- a silicon substrate;
- an array of thermally annealed silicon-based image sensor pixels in the silicon substrate;
- an array of infrared (IR) sensor pixels in a same focal plane as the array of thermally annealed silicon-based image sensor pixels, each IR sensor pixel including an IR-sensitive material comprising at least one of an organic material or a quantum film and each IR sensor pixel comprising an electrode formed on the IR-sensitive material;
- and
- an application-specific integrated circuit (ASIC) bonded to the silicon substrate.
