Photopatterning of two nitrobenzyloxycarbonylcatechol-niobium complexes were investigated. Resulting niobate films were found to selectively adsorb palladium that enabled selective plating of niobium oxide latent images. In combination with selective electroless plating, methods for simultaneous photopatterning of two independent pattern, or aligned and identical pattern transparent electrodes on each side of glass substrate were developed using wavelength selective photoreactions that was consequential to variation in the complexes photoexcitation profile. An electrode material of sheet resistance 1-2 Ω/□ and approximate optical transmittance of 90% was formed by deposition of 5 μm line width and 100 μm pitch copper mesh.

The circuits of system LSIs are increasing in scale and systems designs using the old adjustment methods are becoming more difficult. Therefore, in this research, we developed a new systems design method (named SDSI-Cubic) to achieve a proper design. The method calculates the optimal solution automatically within the estimated ideal system structure using the following steps:
1. Modeling the whole system parametrically.
2. Extracting important design items.
3. Creating an optimization workflow considering the dependencies.
4. Executing the optimization.
Furthermore, we devised an algorithm for automatic execution and also developed cooperation software. Applying our methodology to the conceptual design stage of a system LSI revealed that it is possible to achieve a proper design in consideration of important design items, performance, power consumption, and cost. Thus we could clarify the applicability of this method.
