英文摘要：

Microfabrications of polymer are becoming increasingly important and considered as a low-cost alternative to the silicon MEMS technologies. A micromolding process has been developed, it will adapt for fabricating of planar coils with polymer substrate, enhance the reliability of coils and reduce its cost in manufacture. There is a characteristic of the substrates whose surfaces have dense arrays of narrow grooves （100 μm × 70 μm）. The original pattern is etched on the Surface of silicon wafer by MEMS process. Since PDMS has excellent flexibility, elasticity and replication resolution, we have made transition templates and solved the problem which is difficult to demolding rigidly by transforming patterns technology. We have researched and known the optimal molding method, injecting at medium temperature, curing at room temperature and post curing at high temperature. After electroplating, the stator coils of planar micromotor withth 0.7 mm ickness and Ф20 mm diameter bas been fabricated.
