METHOD FOR FABRICATING BAND PASS FILTER HAVING HIGH RESOLUTION AND ACCURATE FIN PATTERNS

摘要

PURPOSE: A method for fabricating band pass filter is provided to obtain high resolution and accurate fine patterns by using photosensitive Ag paste to forming a conductive layer. CONSTITUTION: A filter layer(21) is formed on an upper surface of a substrate. An exposure process is performed to expose a part of the filter layer. A development process is performed to form a filter pattern by developing the exposed part of the filter layer and removing an unexposed part of the filter layer from the filter layer. A firing process for the filter layer having the filter pattern is performed. The filter pattern includes one or more unit cells having a cuneal opening.
