Abstract

A cantilever having a step-up structure and a method of manufacturing the same. The cantilever includes a substrate, an anchor formed on the substrate, and a moving plate connected to the anchor while maintaining a predetermined gap from the substrate. The anchor includes a first anchor of a predetermined shape and a second anchor perpendicular to an edge of the first anchor while being formed along a longitudinal axis of the moving plate. Accordingly, a deformation of the cantilever caused by the high temperature and pressure in a manufacturing process thereof is considerably reduced. As a result, the yield rate of the cantilever is improved, and the reliability of a product using the cantilever is also improved.
