In the field of Micro-Mechanics, it has been known diffcult to integrate the micro-machine with sensor and source line for the conventional copper line cnanot be used in compact and small size. We developed a system to make thethin copper film as a connect line on the poyurethane pipe (2mm in diameter) by the evaporation technique. This system consists of an evaporation chamber two long branches, substrate hoider and a Linear-Rotary motion feed feedthrough. The results showed that thin copper film coated polyurethanc pipe could be applied th the small medical devices such as the micro active endoscope.

Integrating micro-machined sensors and actuators on the conventional devices with the copper power lines was incompatible to fabricate the mass produced micro electromechanical system (MEMS) devices. To achieve the compatibility of the wiring method between MEMS parts and devices, we developed the three-dimensional sputter-evaporation system that coats micropatterned thin copper films on the surface of the MEMS element. The system consists of a process chamber, two branch chambers, the substrate holder, and a linear-rotary motion feedthrough. Thin copper film was sputtered and evaporated on the biocompatible polymer, Pellethane$^{circed{R}}$ and silicone, catheter that is 2 mm in diameter and 700 mm in length. The metal film coating technique with three-dimensional thin film sputter-evaporation system was developed to apply the power and signal lines on the micro active endoscope. In this paper, we developed the three-dimensional metal film sputter-evaporation system operated on the low temperature for the biopolymeric substrates used in the medical MEMS devices.
