Claim:
1. A method for manufacturing a MEMS device, the method comprising: forming a MEMS structure supported by a substrate; forming a polymer layer on the substrate; forming a second polymer layer on the polymer layer; exposing the polymer layer to a first pattern with a first light having a first wavelength; exposing the polymer layer to a second pattern with a second light having a second wavelength different from the first wavelength; exposing the second polymer layer to a third pattern with a third light; and exposing the second polymer layer to a fourth pattern with a fourth light, wherein the third pattern and the first pattern are a same pattern, the third light and the first light are a same light, the fourth pattern and the second pattern are a same pattern, and the fourth light and the second light are a same light.
