This paper reports a simple process using photoresist as sacrificial layers to fabricate movable microstructures.Movable elements and fixed elements are fabricated simultaneously.The number of required masks is decreased to the least.Comparing with all the existing sacrificial layer materials
the photoresist being used as sacrificial layers has some advantages.The photoresist can be spin coated simply and patterned directly.Otherwise
using photoresist as sacrificial layers does not restrict the thickness of structures and the choice of materials.After some optimization have been taken
the cleanliness of the structures
the adhesion between the fixed elements and the substrate
the speed of the photoresist removal have been improved.
