Etch rates in Z-cut quartz; experiments and simulation Figure 1. Schematic drawings of a right-handed -quartz crystal (a) and its projection on the XY-plane (b). The three X-axes in the figure show the trigonal symmetry. Only one of the Y-axes is shown in the figure. The letters R, r, m, x and sdenote the natural main crystal planes in quartz ...
The depth of wet-etched quartz can reach 500 μm [11], but because of the anisotropy of quartz, the sidewall crystal edges can only be reduced through continuous experiments, and cannot be ...
The etching of the quartz and the Suprasil 2 and Herasil 2 glasses was consistent with a process of ion-enhanced chemical reaction as identified by Steinbruchel. For these substrates, the etch rate was directly dependent on the square root of bias voltage in the RIE and .

Aug 06, 2019· Typical materials that can be etched include glass, alumina, quartz, crystals, silica, agates, porcelain, cermets. and numerous metals and oxides. Advantages. Ion-beam has many advantages which include: The process is almost universal. No chemical reagents or etching .
and etching rate increased with HF concentration, and the transition between various planes can be described by an interaction of adjacent natural crystal planes. Danel et al. [17] realized an acceleration sensor and described the chemical etching of quartz crystals. They gave the etch rates of X, Y, and

Dec 01, 1999· For quartz, Suprasil 2 and Herasil 2, the etch rate was dependent on the square root of bias voltage and on the CHF 3 /CF 4 ratio, indicative of a process of ion-enhanced chemical etching. For the LE, NA and soda-lime glasses, the etch rates were equivalent in both the CHF 3 /CF 4 and Ar plasmas indicating a process of sputter etching.

Reticle employs a selection of gridded RF-ICP ion sources for high energy deposition. Available sources include 4, 10, 14, and 22 cm grid configurations with ion energies up to 1200 eV and beam currents greater than 1000 mA. Self-aligned ion optics are configured specifically for the desired deposition requirements and geometry of your process.
This paper demonstrates the wet etching effects on machined surface of single crystal Si. The machined surface was prepared by irradiating sample with low energy (~ 2keV) ECR sourced Ar + ion beam. Then we performed etching process by HF(2.4%) at 20min,40min and 60min respectively.
In this work, high-frequency one-chip multichannel quartz crystal microbalance (QCM) prepared by deep reactive ion etching (RIE) is presented. The quartz resonators in one-chip with the diameter ...

Aug 11, 2016· The etching of the quartz crystal was carried out using KOH concentration of 25 %, 30% and 35 % by weight at a temperature of 80°C for 2 hours. Aurum palladium (AuPd) was used as a mask to protect the rest of the quartz crystal. The AuPd mask was coated on the quartz crystal by a sputter coater in a high vacuum chamber.
