Abstract
There is provided a process for producing a dielectric thin film of a compound oxide of a high-melting metal and a low-melting metal by vapor-depositing the compound oxide onto a substrate, wherein the improvement comprises irradiating a laser beam onto the substrate or to the vapor phase during vapor deposition. There 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.
