Abstract:
Devices with gamma (γ) grooves are disclosed. The γ grooves can be used to form optical fiber arrays. The γ grooves can be formed using a dry etch, such as RIE, by modifying resist features of an etch mask to have convex curved sidewalls. The profile of the resist features is transferred to the substrate by the dry etch to form the γ grooves. The γ grooves are formed without K containing etchants, avoiding K +  ions contamination of process tools as well as health issues caused by handling alkali containing devices.

Claim (Index 21):
A method of forming a device comprising:\n providing a substrate; forming a patterned photoresist etch mask on the substrate; and performing a dry etch using the patterned photoresist etch mask, wherein the dry etch etches the exposed surface of the substrate to form a gamma (\u03b3) groove having convex curved groove sidewalls.
