Switzerland's microtechnical leadership—spanning the historic watchmaking spine of the Jura Arc (Neuchâtel, Biel/Bienne, Le Locle) to the micro-optics and quantum clusters of Zurich, Vaud, and St. Gallen—demands uncompromising material tolerances. In these environments, carrier plates are not passive holders; they are active process platforms that must survive aggressive chemical vapor deposition (CVD), extreme thermal gradients, reactive ion etching (RIE), and stringent ultrasonic cleaning baths.
Zelvo Quartz fabricates precision fused silica and quartz carrier plates that eliminate particulate shedding and cross-contamination. Utilizing premium Donghai natural crystalline silica and synthetic fused silica ingots, our plates deliver thermal expansion coefficients as low as 5.5 × 10⁻⁷ / K (between 20°C and 320°C). This nearly zero thermal drift guarantees that sub-micron alignment tolerances remain intact during critical wafer handling, thin-film lithography, and sapphire component bonding.
Whether handling gallium nitride (GaN) wafers, delicate silicon balance springs for luxury horology, or microfluidic biochip channels, our carrier plates offer absolute dielectric isolation, non-magnetic properties, and high optical transparency extending from deep ultraviolet (190 nm) to infrared (3.5 µm).
From university research cleanrooms at EPFL and ETH Zurich to high-throughput manufacturing plants in Neuchâtel and Solothurn, our quartz carrier plates are engineered for exact operational environments.
Swiss watchmaking relies on carrier plates during physical vapor deposition (PVD) coating of dials, balance wheels, and sapphire crystals. Our plates provide non-magnetic, heat-resistant nesting trays that withstand temperatures above 600°C without degassing or leaving carbon residues on high-end movement components.
For semiconductor fabs handling 100 mm to 300 mm silicon, silicon carbide (SiC), and lithium niobate substrates. Used in temporary thermal bonding, backside grinding, chemical mechanical polishing (CMP), and laser dicing. Zero warpage and tight thickness uniformity ensure maximum vacuum chuck hold and zero wafer cracking.
Laser-drilled and micro-channeled quartz carrier platforms for automated in vitro diagnostics (IVD), micro-arrays, and biosensors. Fused quartz delivers near-zero auto-fluorescence under UV laser excitation, ensuring signal integrity in DNA sequencing and single-molecule fluorescence detection.
High-energy laser experimental fixtures and cryogenic quantum computing test holders. Synthetic fused silica plates provide ultra-low bubble classifications (DIN ISO 10110 compliant), with OH- content tailored below 1 ppm for IR laser systems or above 1000 ppm for excimer laser ablation resilience.
Our material grades are certified to meet both Swiss micro-machining DIN standards and semiconductor purity baselines.

Adapting quartz substrate fabrication to the evolving demands of Swiss advanced packaging, environmental mandates, and miniaturization.
Swiss microelectronics developers are rapidly adopting chiplet architectures and silicon-interposer stacking. Fused quartz carrier plates with laser-ablated micro-cavities (±2 µm positional accuracy) serve as critical structural supports during temporary bonding and debonding at temperatures exceeding 400°C.
In accordance with strict Swiss Federal Office for the Environment (FOEN) regulations, RoHS directives, and REACH chemical standards, our cleanroom processing eliminates fluorinated residues and heavy metal contaminants, providing full traceability certificates with every batch.
Collaborating with Swiss laboratories exploring 3D glass micro-machining, Zelvo provides optical-grade quartz preforms compatible with picosecond and femtosecond laser inscription. This allows monolithic fabrication of fluidic channels, nozzle arrays, and embedded sensor tracks directly inside the carrier plate.
With Switzerland investing heavily into quantum computing clusters around Zurich and Lausanne, the demand for stress-birefringence-free quartz plates operating at millikelvin temperatures has increased. Zelvo provides precision-annealed quartz components exhibiting zero micro-cracking and stable dielectric performance under deep cryogenic cycling.
Headquartered in Donghai County—widely recognized as China's "Crystal Capital"—Lianyungang Zelvo Quartz Products Co., Ltd. controls the complete supply chain from high-purity natural silica sand to finished, optical-grade machined carrier plates. We eliminate multi-tiered intermediary markups, offering Swiss R&D centers and equipment OEMs high-precision quartz components at transparent, factory-direct terms.
