Abstract
PURPOSE:To measure and evaluate various kinds of fundamental constants regarding a semiconductor in a nondestructive manner by nondestructively measuring the dynamic behavior of a carrier generated inside the semiconductor by being changed with the passage of time due to the intensity-modulated light with which the surface of an object to be inspected is irradiated. CONSTITUTION:Conductive liquids 20, 21 which have been sealed and guided inside appropriate guide means or sealing means 22, 23 come into contact with two parts 30, 31 which are situated at an appropriate separation distance on one surface of an object 10 to be inspected which may be a semiconductor wafer itself 11. The intensity-modulated light 40 guided by means of an optical fiber 50 is incident on a locally microscopic part between the pair of contact parts 30, 31 on the surface of the object 10 to be inspected. The dynamic behavior of a carrier generated by being changed with the passage of time due to the intensity-modulated light with which the surface of the object to be inspected has been irradiated locally or evenly is measured nondestructively. By this setup, the semiconductor can be evaluated nondestructively as it is; kinds of fundamental constants which can be measured can be increased.
