Pan-semiconductor

Applications of Coating Machines in Pan-semiconductor Field and Problems Solved

        Through high-precision and high-uniformity thin film deposition technology, semiconductor substrates are endowed with specific electrical, optical or protective properties, thereby breaking through the physical limitations of silicon wafers or glass substrates themselves, and achieving industrial goals such as higher chip integration, better display image quality, and higher photovoltaic power generation efficiency.
        Different from precision optical applications focusing on light control, the pan-semiconductor industry pays more attention to the regulation of electricity by coating, the precise replication of micro-nano patterns, and the control of large-scale production costs. Specifically, coating machines solve the following key problems in different sub-fields:
        Integrated Circuits/Microelectronics: "Atomic-scale Precision Processing" Determining Chip Performance In chip manufacturing, coating is one of the core processes for constructing transistors and circuits, and its precision directly determines chip performance and yield.
        Mask Manufacturing (Photolithography "Film"): Coating machines deposit high-uniformity photosensitive films or light-shielding films (such as chromium films) on mask substrates. This solves the problem of high-precision replication of circuit patterns onto silicon wafers, and its quality directly determines the final precision of chips.
        Wafer-level Optical and Sensing Integration: With the miniaturization of sensors, coating machines directly deposit complex optical filter films (such as narrow-band filters for face recognition) on CMOS image sensor wafers with completed circuits. This solves the integration problem of optical functions and semiconductor processes, realizing chip-level optical systems.
        Micro-Electro-Mechanical Systems (MEMS) and Advanced Packaging: In MEMS devices and fan-out panel-level packaging, coating equipment is used to deposit electrodes, insulating layers or metal interconnections, solving the reliable manufacturing problem of micron-scale movable structures or high-density interconnections.
        New-type Display: "Nanoscale Color Master" for Perfect Image Quality From mobile phone screens to TVs, coating machines determine the brightness, color and lifespan of displays.
        OLED Panel Manufacturing: High-end coating equipment (such as G6/G8.6 OLED cluster tools) is used to deposit organic light-emitting materials and metal electrodes. It solves the problem of achieving nanoscale uniform film formation on large-area glass substrates, which is the key to ensuring consistent and defect-free light emission of each pixel on the screen.
        Mask Coating: Similarly, display panel manufacturing also requires high-precision masks to define pixel patterns. By depositing uniform thin films, coating machines solve the problem of domestic production of high-resolution masks, breaking the long-term foreign monopoly.
        Photovoltaic/Pan-semiconductor: "Efficiency Booster" for Improving Efficiency and Reducing Costs In the field of photovoltaic cells, coating is the core process to improve photoelectric conversion efficiency, and cost control is crucial.
        Passivation and Power Generation Efficiency Enhancement: In high-efficiency cells such as TOPCon and HJT, coating equipment (such as hot-wire CVD) deposits high-quality passivation films (such as amorphous silicon, silicon nitride) on the silicon wafer surface. This solves the problem of reducing electron recombination loss on the silicon wafer surface, which can increase cell efficiency by ≥0.2%, thereby greatly improving power generation capacity.
