摘要:
A pre-released structure device comprising: at least one first stacking, comprising at least one first layer based on at least one first material, arranged against a second stacking comprising at least one second layer based on at least one second material, at least one closed cavity, formed in the first and/or the second stacking, and arranged between a portion of the first stacking forming the pre-released structure and the second stacking, at least one spacer arranged in the cavity and linking the portion of the first stacking to the second stacking.
摘要:
A device for detecting electromagnetic radiation including at least one detection circuit including a non-cooled thermal detector and an associated reading circuit, and a method for producing the device. The device includes a substrate forming a cavity under vacuum, in which are placed the thermal detector and the reading circuit. A window transparent to radiation is placed above the cavity and ensures the sealing of the cavity. A sealing mechanism hermetically attaches the window on the substrate, and an electrical connection is inserted in the window ensuring a leaktight connection between the detection circuit and processing elements outside the cavity.
摘要:
A stack including a micro-system having an electrical contact to connect the micro-system to the outside world, a substrate having a first layer formed on the substrate, a through hole extending in an axial direction of the substrate and configured to reveal a rear side of the first layer and to provide a passage to electrically connect to the electrical contact, and a cavity located at an end of the through hole close to the first layer, wherein the cavity has dimensions transverse to the axial direction larger than a diameter of the through hole and forms an overhanging edge around the through hole.
