Abstract
PURPOSE:To allow accurate fine-patterning by forming a circuit pattern by laser trimming after first printing a conductive paste on an insulating substrate and then forming a conductive layer by baking and drying the conductive paste. CONSTITUTION:A paste type conductor such as AgPd and Cu is screen-printed on an insulating substrate 11, and a conductive layer 12 is formed therefrom by baking after the drying process. An unpatterned area of the conductive layer 12 is fine-patterned by laser trimming. An area 13 is a part of the conductive layer 12 which is thermally cut by laser trimming. In the laser trimming process, a laser beam 14 is converged by a lens 15 to irradiate the conductive layer 12 locally, whereby the irradiated area can be thermally cut. The laser beam is irradiated on the conductive layer 12 in accordance with a circuit pattern program stored in a laser trimmer, whereby the circuit pattern can be formed on the conductive layer 12.
