14 13 Implementing Big Data : Challenges As-is architecture can t scale out anymore Challenges Current solutions Problems Data Source Complexity of analysis make a well tuned, sophisticated model Low usage rate Process Measurement Massive amount of data Compress data, Use recent data only loss of data value Test Unstructured data New file system (Hadoop,etc) Still using same analysis Lack of storage buy new storage Exponential cost increase Capacity limitation

15 14 Implementing Big Data : Solution Change of Entire Process Aggregation Storage/ Ingestion Analysis Visualization Auto pattern recognition No loss of data Faster ingestion through parallel processing Make summary during ingestion Raw data ingestion All existing analysis reconstructed based on parallel algorithm Implement new types of analysis : machine learning, deep neural network Real time cause analysis Automatic response to data schema Drill down to find root cause Micro scale analysis

16 15 Case : Data Lake Infra One single infra Front end process Back end process MES FDC, Source, Response, Test, Defect, Probe, Yield Data Data Data Data Data Data Big Data Lake results Diverse data analysis Using data from many different machines Can analyze data of longer period No data redundancy Efficient data governance

17 16 Case : Root Cause Analysis Parallel algorithm 1. Implemented parallel/ distributed processing on traditional algorithms 2. Used new types of analysis results 10 times faster analysis Can detect fault in real time Can find anomaly pattern Site managers can do analysis based on their needs

18 17 Case : Micro Quality Analysis and Package Data Analysis Doing complex analysis in real time Solution Chunk ingestion Visualization in distributed in-memory grids We have many wafer inspection equipment but it takes too long time to inspect 1 wafer image. The wafer image processing time and costs are huddles to implement a new macro defect inspection system to ramp-up yield - Quality control manager- Results 100x faster data ingestion Zoom it/out and rotating/overlapping of defect patterns without visual problem
