Controlling stress in MEMS structures
Abstract:
The objects of the present invention are to form MEMS structures of which stress is controlled while maintaining the performance of high-performance LSI, to integrate MEMS Structures and LSI on a single chip, to electrically and chemically protect the MEMS structure and to reduce the stress of the whole movable part of the MEMS structure. To achieve the above objects, a silicide film formable at a low temperature is used for the MEMS structure. The temperature at the silicide film deposition T1 is selected optionally with reference the heat treatment temperature T2 and the pseudo-crystallization temperature T3. T2, the temperature of manufacturing process after the silicide film deposition, is determined does not cause the degradation of the characteristics of the high-performance LSI indispensable. Thus, the residual stress of the MEMS structures may be controlled.
