Abstract
Ensuring safety in semiconductor manufacturing is a critical aspect of maintaining operational efficiency and protecting workers from hazardous conditions. This study proposes a theoretical framework for enhancing safety in semiconductor manufacturing through process optimization and risk assessment. Semiconductor manufacturing involves complex processes, including photolithography, etching, and deposition, each with unique safety risks associated with chemicals, gases, and high-temperature operations. The framework integrates process optimization techniques with a comprehensive risk assessment strategy to identify, mitigate, and monitor potential hazards throughout the production cycle. The framework emphasizes the importance of understanding the interdependencies between process variables and safety risks, using a combination of quantitative and qualitative approaches. Key components of the framework include hazard identification, risk analysis, and the implementation of control measures such as safety interlocks, process alarms, and worker training. Additionally, process optimization is employed to streamline operations while minimizing safety hazards. This includes the application of advanced process control (APC) techniques, which enable real-time monitoring and adjustment of process parameters to maintain safe operating conditions. The theoretical framework incorporates the use of failure modes and effects analysis (FMEA) and fault tree analysis (FTA) for identifying potential failure points in the semiconductor manufacturing process. These tools are employed to assess the likelihood and severity of risks, allowing for the development of mitigation strategies. Furthermore, the framework stresses the role of continuous improvement through data collection, feedback loops, and performance metrics to monitor the effectiveness of safety measures over time. By integrating process optimization with risk assessment, this framework aims to improve safety outcomes in semiconductor manufacturing while enhancing productivity. The study highlights the importance of a proactive approach to safety management, where process design and operational strategies are continually refined to reduce risk and ensure the well-being of workers.
