摘要： Improved disc metal mold provides an improved disc without a ring groove thereon. The improved disc metal mold has a fixed metal mold section and a movable metal mold section for forming a cavity therebetween. One of the fixed and movable metal molds has a stamper having an information signal surface on which an information signal is formed in a form of pits, wherein a fused resin is injected into the cavity to form a disc substrate having a center through hole at the center thereof. The disc metal mold includes the stamper having an center hole at a center thereof for retaining the stamper itself and a retainer for retaining the stamper to engage with the center hole of the stamper. The retainer has a slightly larger diameter at a top surface thereof than a diameter of the center hole of the stamper so that the top surface of the retainer is approximately flush with the information signal surface of the stamper by causing the top end thereof to engage with the center hole of the stamper. Thus, it is possible to provide a recorded disc having a seamless flush information surface without ring groove.

摘要： Provided are a developing method and a developing apparatus that can reduce process time and improve throughput in a developing process using a developer containing organic solvent. The present invention relates to a developing method for performing developing by supplying a developer containing organic solvent to a substrate having its surface coated with a resist and exposed. The developing method of the invention includes a liquid film forming step for forming a liquid film by supplying the developer from a developer supply nozzle to a central portion of the substrate while rotating the substrate, and a developing step for developing the resist film on the substrate while rotating the substrate in a state where the supply of the developer from the developer supply nozzle to the substrate is stopped and in such a manner that the liquid film of the developer would not dry.

摘要： A resist film is formed on a surface of a wafer. Then, a liquid layer used for irradiating the resist film with exposure light rays is formed from a liquid between an optical component facing the resist film and the surface of the wafer. The liquid is capable of transmitting the exposure light rays and has a function of cleaning a surface of the wafer and a surface of the optical component. Then, the resist film is irradiated with the exposure light rays projected from the optical component and transmitted through the liquid layer, to perform light exposure with a predetermined pattern on the resist film. Then, development is performed on the wafer after the light exposure, to form a predetermined pattern on the wafer.

摘要： A substrate treatment method including a first treatment process (S13 to S16) for exposing, heating, and developing a substrate on which a first resist is formed, thereby forming a first resist pattern, and a second treatment process (S17 to S20) for forming a second resist film on the substrate on which the first resist pattern is formed, exposing, heating, and developing the substrate on which the second resist film is formed, thereby forming a second resist pattern. Also, the substrate treatment method compensates a first treatment condition in a first treatment process (S22 to S25) based on a measured value of a line width of the second resist pattern and a second treatment condition in a second treatment process (S26 to S29) based on a measured value of a line width of the first resist pattern.
