Abstract

PURPOSE: To obtain grooved dynamic pressure type bearing with an accurate shape by a method wherein a flat mask made of a film or the like as a photomask is tightly adhered to a surface to be processed by using a tightly adhering jig and only a necessary part thereof is exposed in an exposing step.
CONSTITUTION: On a processing surface of a shaft 2 to be processed, a resist with a uniform thickness is preliminarily formed. Next, a flat mask 1 rolled into a cylindrical shape is mounted to the processing surface of the shaft 2 and, thereafter, a cap 3 of a tightly adhering jig made of a transparent acrylic resin is covered on said mask 1. In this time, said mask 1 is covered so as not to coincide a spliced part thereof with a cut line 31 of the cap 3. Subsequently, in such a condition that the mask 1 is tightly adhered to the shaft accurately by the cap 3, said shaft is transferred to an exposing process in a photoetching step. Then, a necessary part of said shaft is exposed and, after exposure is completed, the cap 3 and the mask 1 is demounted. Next, a desired groove is formed in the etching step and, further, the resist is removed to complete the processing and, thereby, the shaft 2 having a desired groove is fabricated.
