1. A deposition method comprising:
preparing a processing substrate in which a lower electrode, a rib including an aperture overlapping the lower electrode, and a partition including a lower portion arranged on the rib and an upper portion arranged on the lower portion and protruding from a side surface of the lower portion are formed above a substrate;
setting a spread angle of vapor of a first material emitted from a first deposition head to a first angle, and depositing the first material on the processing substrate; and
setting a spread angle of vapor of a second material emitted from a second deposition head to a second angle larger than the first angle, and depositing the second material on the processing substrate on which the first material is deposited, wherein
a nozzle is surrounded by a sleeve having a first length in the first deposition head, in the depositing the first material, and
a nozzle is surrounded by a sleeve having a second length shorter than the first length in the second deposition head, in the depositing the second material.
