Abstract:
1. A method for manufacturing a ceramic green sheet utilizing an exposure process and an development process, comprising the steps of: attaching a photosensitive material including a powder having a specific electric characteristic to a front side surface of a member having a portion that can transmit light used in said exposure process, said photosensitive material being sensitive to said light, and said front side surface being a surface on which a sheet is to be formed; shaping said light into a first pattern and irradiating said photosensitive material with that light from the back side of said member to perform said exposure process with such an exposure amount that only a portion of said photosensitive material that is within a first predetermined thickness will undergo the exposure; shaping said light into a second pattern and irradiating said photosensitive material with that light from the back side of said member to perform said exposure process with such an exposure amount that only a portion of said photosensitive material that is within a second predetermined thickness will undergo the exposure; performing said development process on said photosensitive material after said exposure process; and performing said exposure process only by irradiating said photosensitive material with said light from the back side of said member.
