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 ...
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.

In this paper, miniaturized bi-convex quartz crystal microbalance (QCM) has been fabricated using reactive ion etching (RIE) and melting photoresist technology. Due to the convexity of the resonator surface and the small size of the excitation electrode, the energy of the oscillation is trapped at the center so that very little dissipation ...
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.
A quartz crystal also has reactance, though this reactance is a bit complicated because of the interaction between the three reactive components. ... Each unit is individually calibrated to the correct frequency using high vacuum deposition equipment and ion beam etching machines. Using these techniques, crystals can be manufactured to +/-10ppm ...
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
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 ...

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.
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 .

The etching time of fused quartz and LiNbO 3 are 1.5 h and 4 h, respectively, and the groove depth of these two samples is ∼ 0.7 μm and ∼ 1.3 μm, respectively. During the ion beam etching process, the facets are formed in the sidewalls of samples and photoresist.
B. Plasma etching machine The etching is carried out using a multiplex AOE reactor of STS with an ICP RF generator of 3 kW and a RIE generator of 1.5 kW. The temperature of the substrate holder was varied between 20 and 80°C. The gas mixture used was C4F8/O2 for quartz, SF6/He and CF4/He for LiNbO3 and Ar/C4F8 for PbTiO3 etch.
