Abstract: A lower resist (2) is applied on a semiconductor substrate (1). An upper resist (3) is applied on the lower resist (2). A first opening (4) is formed in the upper resist (3) by exposure and development and the lower resist (2) is dissolved with a developer upon the development to form a second opening (5) having a width wider than that of the first opening (4) below the first opening (4) so that a resist pattern (6) in a shape of an eave having an undercut is formed. Baking is performed to thermally shrink the upper resist (3) to bent an eave portion (7) of the upper resist (3) upward. After the baking, a metal film (8) is formed on the resist pattern (6) and on the semiconductor substrate (1) exposed at the second opening (5). The resist pattern (6) and the metal film (8) is removed on the resist pattern (6) and the metal film (8) is left on the semiconductor substrate (1) as an electrode (9).

Abstract: The brain state support apparatus 1 comprises a stimulus applying device 2, a light detecting device 3, a calculating section 13 for calculating the changed amount of total hemoglobin and the changed amount of oxygen saturation based on the light information, a determination section 14 for determining whether the brain state of the human body is in at least one of a relaxation mode, a concentration mode and an intermediate mode, based on the changed amount of total hemoglobin and the changed amount of oxygen saturation by applying a stimulus of an electrical signal having a predetermined frequency to the acupoint of the human body through the stimulus applying device 2; and a stimulus adjusting section 15 for adjusting a quantity of stimulus to be applied to an acupoint of the human body by the stimulus applying device 2.
