Quartz custom gold-coated plates can be fabricated into various shapes to meet specific application requirements, such as circular, square, or other complex shapes.
Application Scenario
Semiconductor Manufacturing
In semiconductor processes, quartz custom gold-coated plates are used as various components, such as furnace tubes and glass boats, which require direct or indirect contact with silicon wafers in high-temperature environments. The high-temperature resistance and thermal stability of quartz materials are essential in these applications.
Optical Lens Manufacturing
In the optical field, quartz custom gold-coated plates are used to reduce reflection and enhance light transmission by coating a layer of quartz film onto the glass surface, thereby improving the performance of optical equipment. This is widely utilized in the manufacturing of optical instruments such as camera lenses, telescopes, and microscopes.
The gold coating on quartz custom gold-coated plates primarily serves two purposes: first, to enhance their optical performance within specific wavelength ranges, such as reflectivity and transmission; and second, to provide good electrical conductivity, which is crucial in electronic and optoelectronic applications.
In semiconductor manufacturing, quartz custom gold-coated plates can be used to fabricate components such as furnace tubes and glass boats, which require direct or indirect contact with silicon wafers in high-temperature environments. The high-temperature resistance and thermal stability of quartz are critical for these applications.

Frequently asked questions
Quartz glass is a hard and brittle material with excellent physical and chemical properties, extremely high mechanical hardness, good electrical insulation, high temperature and corrosion resistance, low and stable delay performance, good light transmittance, etc. It is widely used in semiconductors, optics, electricity, chemistry, aerospace, automobiles and other fields. Hard and brittle materials are difficult to process, and many fields urgently need cutting processes with small edge collapse, less material loss, low cross-section roughness, and a wide cutting thickness range. The traditional cutting method of quartz glass is mechanical cutting, that is, wheel cutting. Non-traditional cutting methods include water jet cutting, electrochemical discharge wire cutting, continuous laser cutting, etc. Mechanical cutting has low cost, but the contact between the wheel and the material causes large tool wear, and the material is easily contaminated by the tool. Quartz glass is prone to edge collapse, microcracks, and residual stress, which affects the strength and performance of the material! It is difficult to achieve curve cutting and requires post-processing, such as grinding and polishing. Laser cutting does not directly contact the material, has no contact stress, and can perform complex curve cutting. Picosecond laser has the advantages of small spot diameter, high precision, short action time with the material, and small action area, and is suitable for the processing of hard and brittle materials.
