Abstract
An infrared imaging micro-bolometer integrates a membrane assembled in suspension on a substrate by support arms. The membrane includes an absorbing material configured to capture infrared radiations and a thermometric material connected to the absorbing material configured to perform a transduction of the infrared radiations captured by the absorbing material The thermometric material is arranged on a surface area smaller than 0.4 times a surface area of the membrane. The membrane also includes at least one central dielectric layer arranged between the absorbing material and the thermometric material. Recesses are formed in the absorbing material and in the at least one dielectric layer in portions of the membrane devoid of the thermometric material.
