This study aims to fabricate 3 dimensional microstructures on single crystal silicon by nano scale machining using mechanism of friction force microscope (FFM) and subsequent alkaline etching. Machined area by diamond tip acts as a mask against KOH solution because of formation of amorphous layer, and consequently microstructure can be fabricated. The influence of machining conditions on masking effect is studied. As a result, it is found that masking effect can be controlled by adjusting
