The application of laser scanning confocal microscope in micro-electro-mechanical system[J]. Optics and precision engineering, 2008, 16(7): 1241-1246.DOI:
3D micro structure analysis is becoming a powerful tool for charactering micromachining technique. With the deep research and the need for industrialization of MEMS
the importance of micro structure analysis in MEMS is increasing. Because of the advantages of high resolution
non-contact
and quick data-obtaining
etc.
laser scanning confocal microscope (LSCM) is widely used in micro structure analysis. In the paper the imaging basis of LSCM is introduced
and the measurement of great angle and analysis of profile are especially introduced. Meaning while
the advantages and limits in micro structure analysis by LSCM comparing with stepper
SEM and white light interferometer are pointed out.
