Upgraded Precision Slotting Technology Empowers High-end Quartz Slot Plates for Semiconductor and Optoelectronic Manufacturing-Mia
2026/06/22
As a core product of high-end deep-processed quartz components, quartz slotting plates feature ultra-high cleanliness, micron-level precise slotting, excellent high-temperature resistance and corrosion resistance, serving as essential basic components for semiconductor manufacturing, optoelectronic coupling, precision equipment and new energy production. With continuous breakthroughs in domestic technologies including precision cold working, micro-nano slotting and stress-free post-processing, high-end domestic quartz slotting wafers have completely abandoned extensive processing modes. Their accuracy, yield rate and operational stability have been greatly improved, accelerating import substitution and emerging as a new growth driver in the quartz consumables industry.
Manufactured from high-purity transparent quartz substrates through elaborate cutting, precision slotting, polishing and stress relief procedures, quartz slotting wafers are customized special quartz structural parts. Different from ordinary flat quartz sheets, they are characterized by precisely controllable slot structures, uniform dimensional tolerances and burr-free, ultra-flat cutting surfaces. Adopting low-hydroxyl processes with a substrate purity of over 99.99%, the products can withstand temperatures above 1100°C and deliver superior deep-ultraviolet light transmittance, stable chemical properties and zero metal precipitation. Fully compliant with the stringent cleanliness and high-temperature working conditions of high-end manufacturing, they are core supporting components for precision bearing, positioning, light transmission and isolation equipment.
Technological innovation serves as the core driving force for the upgrading of the domestic quartz slotting wafer industry. In the past, high-precision quartz slotting products relied on imported processing equipment and overseas technologies, suffering from large slot spacing errors, rough cut surfaces, edge chipping and high-temperature deformation, which limited their application to low-end general scenarios. In recent years, domestic enterprises have fully upgraded their precision processing systems equipped with high-precision laser slotting and integrated CNC micro-cutting equipment. The upgraded production line supports customized precision processing with slot widths ranging from 0.1mm to 5mm and slot depths from 0.05mm to 10mm, enabling fine adjustment of slot shape, spacing and parallelism throughout the process and thoroughly solving long-standing industry problems such as fragmentation, burrs and residual processing stress.
