Electrical Melting Quartz Ingot

‌Semiconductor Grade Electrical Melting Silica Ingot: Applications and Optical Properties‌

‌Key Applications‌

1. ‌Semiconductor Manufacturing‌

• Utilized as mask layers, isolation layers, and protective coatings in integrated circuits (ICs) and microelectronic devices due to ultra-high purity (>99.999%) and thermal stability‌14.

• Critical in photolithography processes for patterning semiconductor wafers, ensuring precision in nanoscale fabrication‌4.

• Serves as a dielectric material in high-temperature processing steps (e.g., annealing or oxidation)‌4.

2. ‌Optical Components‌

• Used in high-performance optical systems (e.g., lenses, prisms) and fiber optics, leveraging its exceptional transparency and low optical loss across ultraviolet (UV) to infrared (IR) spectra‌1.

‌Optical Performance (English Description)‌

• ‌Transparency‌: Exhibits superior transmittance (>90%) in the UV-VIS-NIR range, ideal for precision optics and laser systems‌1.

• ‌Low Dielectric Loss‌: Demonstrates minimal dielectric loss (tan δ < 0.0021 at 10 GHz), enabling efficiency in high-frequency communication and microwave applications‌5.

• ‌Thermal Stability‌: Maintains optical integrity under extreme temperatures (up to 1,200°C), critical for aerospace and advanced semiconductor packaging‌45.

‌Note‌: The term "electrical melting" refers to a high-purity manufacturing process, ensuring minimal impurities and structural homogeneity for semiconductor and optical-grade performance‌
