Assignee: APPLIED MATERIALS, INC.
Field: Optics (Instruments)
Classification: CPC G  B | IPC G

Claim 9:
10. A system for fabricating a diffractive optics element (DOE) comprising:
one or more processors; and
a memory storing instructions that, when executed by the one or more processors, cause the system to:
receive a substrate having a uniform DOE provided thereon; and
deposit a film layer having a varying thickness across a surface of the substrate using an inkjet process, wherein depositing the film layer comprises:
depositing a first solution having a first refractive index using a first nozzle;
depositing a second solution having a second refractive index using a second nozzle, the second refractive index being different than the first refractive index; and

adjusting a volume of the first solution relative to a volume of the second solution to vary the refractive index and thickness of the DOE, to form an encapsulated uniform DOE.
