A post-supported bolometer pixel and a process for manufacturing it comprising the steps of depositing a sacrificial layer over a substrate with readout integrated circuit pads that connect to the integrated circuit; forming vias through the sacrificial layer to the metal pads connecting to the readout integrated circuit; filling the vias with metal and polishing said metal to the surface of the sacrificial layer; forming microbolometer pixel layers over the filled vias and sacrificial layer; and removing the sacrificial layer to leave a post-supported pixel.

Post-supported microbolometer pixel

A method for manufacturing microscopic canals within a semiconductor is disclosed. A shallow trench is initially formed on a substrate using a patterned photoresist. After the patterned photoresist has been removed from the substrate, a separation layer, such as a Titanium layer, is deposited on the substrate. Subsequently, a cap layer, such as a Titanium nitride layer, is deposited on the separation layer. Both the separation layer and the cap layer are then polished off from the surface of the substrate. Finally, a Tungsten layer is deposited on the substrate and in the trench such that a microcanal will be formed within the trench as a result.
