Abstract:
1. A film formation method comprising the steps of: placing a deposition source to face a three-dimensional curved surface of a deposition object; adjusting a first angle formed between a deposition direction of the deposition source and a normal direction of a first region of the three-dimensional curved surface by changing the deposition direction of the deposition source; performing a first deposition to the first region while moving the deposition source so as to form a first layer; after performing the first deposition, adjusting a second angle formed between the deposition direction of the deposition source and a normal direction of a second region of the three-dimensional curved surface by changing the deposition direction of the deposition source; and performing a second deposition to the second region while moving the deposition source so as to form a second layer, wherein the first angle is maintained substantially constant during the step of performing the first deposition, wherein the second angle is maintained substantially constant during the step of performing the second deposition, and wherein the first angle and the second angle is substantially same.
