Abstract: PURPOSE: To enable simultaneous manufacture of a multi-layered thin-film interconnection structure and a ceramic substrate with a good yield by forming on a transmitting substrate a separation layer which is less formed, when reacted with a predetermined electromagnetic radiation. CONSTITUTION: A polymer layer 2 is cut off by applying an ultraviolet light 10 from a scanning layer, via a transmitting substrate 1 to the polymer layer 2. Since a metallic layer 3 acts as a reflecting layer, the ultraviolet light 10 cannot reach an interconnection structure 4. As a result of the laser cut-off, monomer pieces, that is, an emitted substance gas is trapped between the substrate 1 and reflecting metal layer 3, thus forming voids 15 within the polymer layer 2. The polymer layer 2 is formed less due to the voids 15, and thus can be separated (removed) from the substrate 1. After the structure 4 has been removed from the substrate 1, the structure 4 is supported by a metal ring (frame) 5. At this time point, the structure can be applied to an electrically good glass ceramic substrate.

Abstract: PURPOSE: To constitute a method and apparatus for writing a bar code in a continuous pattern by adding a step for marking a substrate so as to obtain a serpentine pattern having a connection segment for alternately linking data segments at both ends. CONSTITUTION: A series of connection segments for linking adjacent bar code data segments are used. These connection segments are set to the ends of the data segments to suitably connect the data segments vertically. However, the connection segments may be actually patterns such as circular arc patterns or the like corresponding to the continuous operation of a laser. In order to provide continuity to a writing path, the connection segments are alternately arranged so as to obtain a serpentine pattern. Further, in order to accurately start the laser operation to a substrate, especially, in such a case that the substrate is plastic or metal, the start segment vertically extending outwardly from one end of a first data segment is used. Therefore, the effect of laser irradiation on the substrate is continued to become uniform.
