DESIGN AND DEVELOPMENT OF A COMPUTER ASSISTED FMEA ANALYSIS TOOL FOR THE SEMICONDUCTOR INDUSTRY

Abstract

The use of Failure Mode and Effect Analysis (FMEA) has become widespread in various industries to address quality and reliability issues that may occur in a system or process. However, the risk assessment process using traditional FMEA is very time-consuming because it requires the evaluator to assess the risk for each identified potential failure mode one by one, based on the extracted historical data. Without proper consideration of the system or process being evaluated, the evaluator may make incorrect judgments, causing the FMEA results to be inaccurate and unreliable. In this study, an interactive FMEA tool that uses a standard risk factor input as the main reference was developed using Excel software and Tableau software. Semi-structured interviews were conducted at the initial stage of the study to obtain basic information about the existing FMEA approach in the semiconductor industry. With this information, a standard reference for risk factor input was established for the FMEA tool. The developed tool was then tested in the real semiconductor industry to validate its effectiveness and practicality. The results show that the developed interactive FMEA tool holds significant potential for industrial usage in terms of streamlining the FMEA analysis process, providing a comprehensive visualization of the identified potential failure modes, and improving information sharing within the organization. With the presence of this interactive FMEA tool, users can not only produce more accurate and reliable FMEA results based on built-in risk factor input standards, users can also view the generated FMEA results online through the Tableau dashboard.
