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 1):
A method of fabricating a slanted surface-relief structure in a material layer, the method comprising:\n injecting a first reactive gas into an reactive ion source generator, wherein the first reactive gas comprises a low-molecular-weight gas; generating a plasma in the reactive ion source generator, the plasma including reactive ions; 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, wherein 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.
