Abstract:
A method of manufacturing a Fabry-Perot interference filter includes a forming step of forming a first thinned region, a first mirror layer, a sacrificial layer, and a second mirror layer are formed on a first main surface of a wafer, and the first thinned region in which at least one of the first mirror layer, the sacrificial layer, and the second mirror layer is partially thinned along each of a plurality of lines is formed; a cutting step of cutting the wafer into a plurality of substrates along each of the plurality of lines by forming a modified region within the wafer along each of the plurality of lines through irradiation of a laser light, after the forming step; and a removing step of removing a portion from the sacrificial layer through etching, between the forming step and the cutting step or after the cutting step.

Claim (Index 5):
The method of manufacturing a Fabry-Perot interference filter according to  claim 3 ,\n wherein in the cutting step, in a state in which the expanding tape is attached to the stress adjustment layer side, the laser light is incident on the wafer through the expanding tape from the expanding tape side.
