Abstract:
1. A deposition method comprising the steps of: providing a first light absorption layer on a first surface of a first substrate; providing a material layer over and in contact with the first light absorption layer and the first surface of the first substrate, providing a second light absorption layer on a second surface opposite to the first surface of the first substrate; making the first surface of the first substrate and a deposition target surface of a second substrate face to each other; and depositing part of the material layer on the deposition target surface of the second substrate in such a manner that irradiation with laser light having a repetition rate of greater than or equal to 10 MHz and a pulse width of greater than or equal to 100 fs and less than or equal to 10 ns is performed in a direction from the second surface of the first substrate to the first surface of the first substrate through the first substrate to selectively heat part of the material layer which overlaps with the first light absorption layer, wherein the first light absorption layer comprises metal nitride.
