摘要： There is provided a substrate inspection method. The method includes: maintaining a vacuum in said inspection chamber; isolating said inspection chamber from a vibration; positioning the substrate on a stage in the inspection chamber; selecting an evaluation parameter according to a kind of said processing apparatus; and determining inspection regions of the substrate so that an inspection time required per a lot of the substrate is equal to a processing time spent for said processing step required per a lot of the substrate. The method also includes radiating a primary electron beam from an electron gun; deflecting the primary electron beam with an E*B unit; irradiating said inspection regions of the substrate with the deflected primary electron beam; and projecting secondary electrons emitted from said substrate through the E*B unit onto a detector with a secondary optical system.
