Abstract
A method of forming a focal plane array by: preparing a first wafer having sensing material provided on a surface, which is covered by a sacrificial layer; preparing a second wafer including read-out integrated circuit and a contact pad, which is covered by another sacrificial layer into which are formed support legs in contact with the contact pad, the support legs being covered with a further sacrificial layer; bonding the sacrificial layers of the first and second wafers together such that the sensing material is transferred from the first wafer to the second wafer when a sacrificial bulk layer of the first wafer is removed; defining a pixel in the sensing material and forming a conductive via through the pixel for providing a connection between an uppermost surface of the pixel and the supporting legs; and removing the sacrificial layers to release the pixel, with the supporting legs underneath it.
