Abstract:
Techniques for fabricating a slanted structure are disclosed. In one embodiment, a method of fabricating a slanted structure in a material layer includes injecting a first reactive gas into an reactive ion source generator, generating a plasma that includes reactive ions in the reactive ion source generator, extracting at least some of the reactive ions from the plasma to form a collimated reactive ion beam towards the material layer, and injecting a second reactive gas onto the material layer. The collimated reactive ion beam and the second reactive gas etch the material layer both physically and chemically to form the slanted surface-relief structure. In some embodiments, the first reactive gas includes a low-molecular-weight gas (e.g., H 2  or He). In some embodiments, a surface layer of the internal cavity of the reactive ion source generator includes a layer of an oxide material (e.g., aluminum oxide or Y 2 O 3 ).

Claim (Index 20):
The CARIBE system of  claim 15 , wherein:\n the first reactive gas comprises at least one of CF 4 , CHF 3 , CH 2 F 2 , CH 3 F, C 4 F 8 , C 4 F 6 , C 2 F 6 , C 2 F 8 , NF 3 , CLF 3 , N 2 O, N 2 , O 2 , SF 6 , H 2 , Cl 2 , BCl 3 , HBr, Ar, He, or Ne; and the second reactive gas comprises at least one of CF 4 , CHF 3 , N 2 , O 2 , SF 6 , Cl 2 , BCl 3 , or HBr.
