Equipment Engineering System – BISTel

BISTel switched from Oracle to Altibase to bolster its quality control and flaw detection for its semiconductor business, resulting in an unprecedented real time system and 27 times growth in productivity.

Use Case: Equipment Engineering System

Current Customers: BISTel

Industry: Manufacturing

Who

BISTel is a South Korea’s leading semiconductor chip manufacturer that specializes in Equipment Engineering System (EES) solutions.

Problem

BISTel suffered from inadequate quality control. The core issue was the inability to track defects and change requirements in real time. Data was stored on multiple databases, which perpetuated BISTel’s incapacity to monitor and react to these issues. With latency issues, the automated system could not pinpoint the imperfections.[1]

  • Numerous workstations relying on multiple databases led to substantial performance degradation, triggering uncontainable defects.
  • Vital quality protocols were breached due to delay in processing product composition data.
  • The increase in customer demand caused further erosion in quality control, prompting unmanageable blows to profitability and reputation.

Solution

BISTel implemented Altibase in hybrid mode in 2006.[2] Altibase captured defective data in real time and alerted BISTel’s quality control personnel to take immediate action at the time of occurrence.[3] The deployment took only three months: two months for application development and one month for performance tuning.[4]

Results

  • Precise product manufacturing processes enhanced quality and yield while decreasing scrap.
  • BISTel’s revenue, profit, and reputation are backed by its superior products.
  • Customer satisfaction, loyalty and attraction are maximized.
  • Altibase enabled BISTel to increase productivity by 27 times.

Technical Details – Equipment Engineering System

BISTel achieved outstanding results with its EES framework by leveraging the key features of Altibase , specifically in the areas of high performance, application development and data integration.

BISTel’s EES is commonly used in semiconductor and flat panel display manufacturing. EES gathers data for semiconductor manufacturing equipment and analyzes it according to production plans, scheduling, operation status and other dimensions. The role of BISTel’s EES framework is to feed data to EES.

BISTel needed to speed up the manufacturing process to improve product quality and reduce error rates.

BISTel’s technical objective was to manage the increasing amount of data to control semiconductor manufacturing equipment, provide real time monitoring and analysis and seamlessly link Equipment Engineering (EE) data with EE application.

In the core of the EES framework, there was a conventional on-disk RDBMS for data management. However, the on-disk DBMS did not have the capacity to process large volumes of data in real time. This was the main requirement for the EES framework allowing for increased speed in the overall manufacturing process.

BISTel decided to design a system using Altibase in in-memory only mode as the front to Oracle’s on-disk DBMS. In this architecture, Altibase was used for the processing and analysis of large volumes of data at extreme speeds whereas Oracle’s on-disk DBMS was used for managing historical data that did not require real time processing power.

BISTel also implemented an in house data integration tool to synchronize data between Altibase ‘s in-memory DBMS and Oracle’s on-disk DBMS. Altibase ’s real time performance remained constant even when its workload also required data synchronization tasks to another database.

Altibase as a full-featured and standards compliant DBMS also made it easy for BISTel to implement this new system by allowing BISTel application developers to work with industry standard connectivity interfaces and familiar programming languages. Using JDBC, Java and standard SQL, BISTel application developers implemented and deployed the EES Framework within 2 months.

[2] BISTel deployed the Altibase hybrid technology on an 8-core HP Superdome Server in a stand-alone configuration.

[3] BISTel’s quality control personnel received defective data in real time on a micro-level per product.

[4] Prior to implementing Altibase , the processing speed of BISTel’s legacy system was about 80ms per transaction. With Altibase , BISTel was able to enhance its transaction speed to 3ms per transaction, achieving performance boost by 27 times.
