Abstract Photonic nanocavities with high quality (Q) factors are essential components for integrated optical circuits.The use of crystalline silicon carbide (SiC) for such nanocavities enables the realization of devices with superior properties. We fabrie ultrahigh-Q SiC photonic crystal nanocavities by etching air holes into a 4H-SiC slab that is prepared without using hydrogen ion
In this paper is detailed a technique for the plasma etching of silicon carbide (SiC) utilizing aluminum nitride (AlN) as a masking material. The fabriion technique enables the use of non-metallic etch masks to etch SiC which can aid in preventing micromasking defects on the etch surface and degradation in the health of plasma etch tools. This is the first report of this fabriion process
Furthermore, this process also exhibits very high selectivity (>1000:1) with conventional hard masks such as silicon carbide, silicon dioxide and silicon nitride, enabling deep Si etching. In these initial studies, etch rates as high as 9.2 μm/min could be achieved at 1150 °C.
2014/2/12· We investigate the effects of hydrogen plasma treatment (HPT) on the properties of silicon quantum dot superlattice films. Hydrogen introduced in the films efficiently passivates silicon and carbon dangling bonds at a treatment temperature of approximately 400°C. The total dangling bond density decreases from 1.1 × 1019 cm-3 to 3.7 × 1017 cm-3, which is comparable to the defect
Etching was already used in antiquity for decorative purposes. Etched carnelian beads are a type of ancient decorative beads made from carnelian with an etched design in white, which were probably manufactured by the Indus Valley civilization during the 3rd …
In this article, we describe more than 100-μm-deep reactive ion etching (RIE) of silicon carbide (SiC) in oxygen-added sulfur hexafluoride (SF 6) plasma. We used a homemade magnetically enhanced, inductively coupled plasma reactive ion etcher (ME-ICP-RIE) and electroplated nickel masks. masks.
Silicon carbide (SiC) was etched in a N F 3 ∕ C H 4 inductively coupled plasma. The etch process was modeled by using a neural network called generalized regression neural network (GRNN). For modeling, the process was characterized by a 2 4 full factorial experiment with one …

tensity plasma such as magnetron plasma [4], ICP [5] and helicon plasma [6] in order to achieve a high etching rate of 6H–SiC. If we look for wet etching solutions for 6H–SiC, unfortunately, there is no etchant that can attack silicon car-bide at room temperature
Recent developments in the use of high density plasma sources to achieve fast etching rates (in some cases over 1 μm min −1 for bulk 4 H-SiC) are discussed. These sources are likely to play a dominant role for processing of SiC MEMS devices since they are capable of producing etch depths from 0.1 to 100 μm with minimal disruption of the SiC surface.

An approach of fabriing pseudoperiodic antireflective subwavelength structures on silicon carbide by using self-asseled Au nanopatterns as etching mask is demonstrated. The nanopatterning process is more time-efficiency than the e-beam lithography or nanoimprint lithography process.
