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 5):
The method of  claim 1 , wherein extracting at least some of the reactive ions from the plasma to form the collimated reactive ion beam comprises:\n applying an extraction voltage on an extraction grid adjacent to the reactive ion source generator; and applying an acceleration voltage on an acceleration grid to extract and accelerate at least some of the reactive ions, wherein the extraction grid and the acceleration grid are aligned; and wherein the acceleration voltage is lower than the extraction voltage.
