Abstract: A process for manufacturing a thin film platinum temperature sensor capable of removing platinum remaining at a boundary after laser trimming is disclosed. In the process, a surface of an alumina substrate is cleaned and dried. Platinum is deposited on the alumina substrate in the form of a thin film. The thin film of platinum is heat-treated. An active photosensitive material is spin-coated on the heat-treated thin film of platinum, soft-baked, exposed to helium light, photoprinted, and then hard-baked. The heat-treated thin film of platinum is chemically etched by using an etching solution so that a serpentine type pattern is formed on the thin film of the platinum. A leading wire is connected to both terminals of the formed pattern. The formed pattern is coated by means of a protective film or sealed in a glass or metal pipe.
