Claim 13:
14. An electronic device manufacturing method, comprising:
generating laser light using an excimer laser apparatus including a laser chamber;
emitting the laser light to an exposure apparatus; and
exposing a photosensitive substrate to the laser light in the exposure apparatus to manufacture an electronic device,
the laser chamber including:
a container which contains laser gas therein;
a pair of discharge electrodes arranged in the container;
a cross flow fan configured to supply the laser gas to a discharge space between the discharge electrodes, the cross flow fan including a rotation shaft with which the cross flow fan rotates in a predetermined rotation direction and a plurality of blades, each longitudinal direction of which is parallel to an axial direction of the rotation shaft; and
a stabilizer arranged outside a rotation trajectory of the cross flow fan, and arranged such that a difference in the rotation direction between a maximum position and a minimum position of an end portion on a side opposite to the rotation direction is larger than 0 and is smaller than an interval of two blades adjacent to each other among the plurality of blades blades,
wherein a position of the end portion in the rotation direction changes in accordance with a position of the end portion in the axial direction, and
wherein a cycle of the position of the end portion in the rotation direction is equal to or smaller than twice a wavelength of an acoustic wave generated between the cross flow fan and the stabilizer.
