Abstract:
1. A vapor deposition apparatus comprising: a linear head including a plurality of nozzles distributed along a length of the head and including an inlet through which a deposition vapor can be injected into the head at a corresponding pressure for subsequent ejection through the nozzles and toward one or more definable deposition planes spaced apart from the head; a plurality of deposition speed sensors distributively disposed in correspondence to the length of the head and configured for measuring effective deposition rates of the deposition vapor along at least a first of the definable deposition planes when the deposition vapor is ejected from corresponding ones of the nozzles toward the at least first deposition plane; and an angle controller operatively coupled to and responsive to the deposition speed sensors and configured to controlling an angle of inclination of the linear head with respect to a second predetermined deposition plane, said second predetermined deposition plane being one at which a surface of a to be supplied substrate is to be disposed so as to receive the deposition vapor ejected from the nozzles when inlet at said corresponding pressure, where during actual deposition, a surface of the supplied substrate is coincident with said predetermined second deposition plane and the head is inclined under control of the angle controller at an angle of inclination relative to the second deposition plane, the angle being determined according to respective measurements made by the deposition speed sensors of the corresponding effective deposition speeds from the nozzles of the inclined head to the predetermined first deposition plane when the sensors occupy the predetermined first deposition plane.
