    摘要: The present invention relates to a pyroelectric infrared ray sensor fabricated by using MEMS processes, wherein an infrared ray absorption layer disposed on the most top portion of the infrared ray sensor assembly is formed with a silicon oxide film (SiO2) to exhibit an excellent absorption efficiency with respect to the infrared wavelength band of 8 to 12 mm and function as a protective film for a sensor pixel. In addition, an infrared ray absorption layer, support arms and posts are formed in a single body to allow the sensor assembly to be robust and fabricating processes to be remarkably reduced to increase a process yield.
