摘要
There is provided a process for producing a dielectric thin film of a perovskite oxide on a substrate by a vapor-deposition process which includes vaporizing the oxide and irradiating the oxide vapor or the substrate with a laser beam.PPThere is also provided a pyroelectric type of sensor comprising: a MOS element including a drain electrode, a source electrode, a gate electrode and an Si semiconductor and a film of a ferroelectric or pyroelectric material formed on the drain electrode, the drain electrode being made of a material which exhibits a good ohmic contact with Si or SiO.sub.2 and has a lattice constant close to that of ferroelectric or pyroelectric material.
