Semiconductor Battery Laser Filming Equipment Semiconductor battery laser filming equipment is a highly specialized system designed for precision thin-film deposition and patterning in the manufacturing of advanced semiconductor-based batteries, such as lithium-ion and solid-state batteries. This equipment utilizes laser technology to achieve micron-level accuracy in film formation, ensuring high performance, durability, and energy efficiency in next-generation battery cells. Key Components and Functionality 1. Laser Source – The system employs high-power pulsed or continuous-wave lasers (e.g., fiber lasers, excimer lasers) with precise wavelength control to ablate, anneal, or deposit thin films on battery electrodes. The laser's energy density and pulse duration are optimized to minimize thermal damage while ensuring uniform film adhesion. 2. Optical System – Advanced beam shaping optics, galvanometer scanners, and focusing lenses enable precise laser positioning and patterning. This ensures consistent film thickness and minimizes defects in critical battery components like anodes, cathodes, and solid electrolytes. 3. Substrate Handling – Automated stages with high-precision motion control allow for accurate alignment and movement of battery substrates (e.g., silicon wafers, metal foils) during laser processing. Some systems integrate vacuum or inert gas environments to prevent oxidation during filming. 4. Thin-Film Deposition & Patterning – The equipment supports various techniques, including: - Laser Chemical Vapor Deposition (LCVD) for depositing conductive or insulating layers. - Laser Ablation to remove unwanted material or create microstructures for enhanced ion transport. - Laser Annealing to improve crystallinity and conductivity of electrode films. 5. In-Situ Monitoring & Control – Real-time sensors (e.g., pyrometers, CCD cameras) and closed-loop feedback systems ensure process stability, detecting deviations in film thickness or composition to maintain quality. Applications - Lithium-Ion Batteries: Laser-deposited thin films enhance electrode conductivity and cycle life. - Solid-State Batteries: Precise laser patterning enables uniform solid electrolyte layers, reducing dendrite formation. - Flexible Batteries: Ultrafast lasers enable thin-film deposition on flexible substrates without mechanical stress.
