Quartz Layering
In the industrial field, regarding “Quartz layering” (related technologies or applications of quartz layering):
In terms of fused quartz glass manufacturing
There is a process for vacuum melting fused quartz glass, which adopts a method of filling the crucible in layers, that is, filling quartz sand into the crucible layer by layer for vacuum melting.
The fused quartz glass obtained through this layer-by-layer filling and melting process has fewer defects and higher light transmittance compared with other methods.
It has important applications in industries with high quality requirements for fused quartz glass, such as optical instruments and semiconductor manufacturing.
In the semiconductor manufacturing field
In semiconductor wafer manufacturing, a photomask is a copy of a layered design circuit diagram generated on a thin chromium film layer plated on a glass or quartz plate.
The photolithography process is a key step in semiconductor manufacturing. As the substrate material of the photomask, the quality and characteristics (such as surface flatness, purity, etc.) of the quartz plate are crucial for accurately replicating the circuit diagram and thereby manufacturing high-performance and highly integrated chips.
In addition, the thin-film process is a processing technology for forming thin films on the wafer surface. Although it is not directly called “Quartz layering”, in some semiconductor manufacturing processes, relevant carrying and reaction vessels made of quartz are used. And the layered deposition of thin films (such as insulator, semiconductor or conductor thin films) plays a role in separating, connecting and protecting between circuits, which is closely related to the overall manufacturing process.
In the liquid crystal display (LCD) and other electronic manufacturing industries
There are LCD quartz layering products, as well as FOG (Film On Glass) quartz pressing parts and FPC (Flexible Printed Circuit) quartz-related products.
These quartz layering products play a role in components such as the display modules of electronic devices, for example, ensuring the stability, light transmittance of liquid crystal displays and the accuracy of signal transmission.
As key components, they are involved in the manufacturing process of various electronic products such as mobile phones, computers, and TVs.
