Our positioning

The semiconductor industry is a vast and intricate industrial chain system.
In the entire industrial chain, semiconductor materials occupy the upstream core segment. Within this segment, wafer manufacturing materials encompass silicon wafers, photomasks, photoresists and their auxiliary materials, process chemicals, electronic specialty gases, polishing slurry and pads, target materials, etc. Packaging materials, on the other hand, include lead frames, packaging substrates, ceramic substrates, bonding wires, packaging resins, chip bonding materials, etc. Each major category of materials is further subdivided into dozens to hundreds of specific products, forming hundreds of sub-industries and building a vast and intricate supply network.
Guangcheng Precision's products and services primarily focus on the front-end processes of wafer manufacturing, especially in the critical pre-lithography steps such as wafer cutting, grinding, and polishing. We provide customers with high-quality, high-precision material and technology solutions.

The precision optics industry chain can be divided into three segments: upstream, midstream, and downstream
Upstream: It primarily involves the production and manufacturing of optical raw materials, with participants mostly being optical glass manufacturing enterprises. The optical materials industry is a fundamental component of the entire optical industry and is currently in a relatively mature market stage.
Midstream: This includes the processing and manufacturing of optical components and their assemblies, where optical glass undergoes processes such as cutting, grinding, and coating to produce various optical components, lenses, and other products. This segment can be further divided into two major categories: traditional optical components and assemblies, and precision optical components and assemblies.
Downstream: It refers to the application fields of optical products, encompassing industries such as consumer electronics, instrumentation, semiconductor manufacturing, automotive lenses, lasers, and optical communication. It represents the ultimate demand end for optical components.
Guangcheng Precision's products and services primarily focus on the midstream segment, especially the key processes before coating, such as cutting, machining, grinding, and polishing of optical glass, providing customers with high-precision and high-stability optical processing solutions.

As an important branch of functional ceramics, precision ceramics are widely used in high-end fields such as electronics, electrical engineering, machinery manufacturing, medical devices, and aerospace due to their excellent mechanical strength, high wear resistance, superior thermal stability, and outstanding chemical inertness. Precision ceramic materials are typically made from main raw materials such as alumina, silicon nitride, aluminum nitride, zirconia, etc. Through advanced molding, sintering, and surface processing techniques, high dimensional accuracy and complex shapes can be achieved.
With the advancement of smart manufacturing and emerging technologies, the demand for precision ceramics in industries such as semiconductor equipment, sensor components, high-frequency communication, and new energy continues to grow, propelling the industry towards higher performance and precision. Kousei Seimitsu is committed to providing customers with comprehensive services spanning from material research and development, processing and manufacturing, to application solutions, thereby facilitating industrial upgrading and technological innovation.
