A biocompatible thin film electrical component is configured for use in a human body or other ionic liquid environment. A polyimide substrate is bonded to a glass carrier plate sized for handling by automatic equipment and a multiple-layer metal conductor is deposited on the substrate and patterned to define an electrical circuit or biosensor. The polyimide and the glass establish a bond therebetween that withstands handling yet is know using biocompatible releasing agents and techniques. The polyimide substrate and glass carrier plate preferably have similar thermal expansion properties to reduce the likelihood of fracture and delamination problems during release of the substrate from the carrier plate. An insulation layer covers the metal conductor and, in one embodiment, is made of polyimide having a cure temperature lower than the temperature at which interediffusion occurrs in the metal layers in the conductor.
