Pulsed femtosecond-laser Machining and deep reactive ion etching of diamond

Deep Reactive Ion Etching (DRIE)

Crystallographic Orientation Dependent Reactive Ion Etching in Single Crystal Diamond.

Sculpturing desired shapes in single crystal diamond is ever more crucial in the realization of complex devices for nanophotonics, quantum computing, and quantum optics. The crystallographic orientation dependent wet etch of single crystalline silicon in potassium hydroxide (KOH) allows a range of shapes to be formed and has significant impacts on microelectromechanical systems (MEMS), atomic f...

Reactive ion etching

The reactive ion etching ofInP, InGaAs, and InAIAs in CClzF2/02 or C2R(/H2 discharges was investigated as a function of the plasma parameters pressure, power density, flow rate, and relative composition. The etch rates of these materials are a factor of 3-5 X faster in CC12F 2/0 2 (-600--1000 AminJ ) compared to CzHJH2 (160-320 AminI ). Significantly smoother morphologies are obtained with C2H6...
