Wafer Yield Management

• Wafer yield management is an essential process in
  the manufacturing of semiconductors. Its primary
  objective is to identify and address factors that
  may affect the quality and efficiency of the
  wafer manufacturing process. This process is
  crucial because it directly impacts the cost of
  production and profitability of the business.

Ramping all the Semiconductor Manufacturing
Processes

• The process of wafer yield management involves
  the identification of the root cause of yield
  loss by performing root cause analysis in
  semiconductor, analyzing data and trends, and
  implementing corrective actions. Several factors
  can affect the wafer yield, including defects in
  the chip manufacturing process, variability in
  the production equipment, and errors in the
  design of the chip itself.

Tracking of Yield Results

• To ensure profitability and product quality, it
  is essential to optimize all semiconductor
  manufacturing processes and monitor the yield
  results. This involves optimizing processes,
  improving yield, and increasing profitability.
  Automating the tracking of test results and
  trends is a critical aspect of wafer yield
  management. This helps to assess the robustness
  and profitability of the manufacturing yield
  processes in real-time, and identify trends, and
  patterns that impact yield and profitability.

Automated Tracking of Test Results

• Real-time cluster detection semiconductor and
  resolution of yield issues are critical in wafer
  yield management. It ensures that any issues that
  could potentially affect the manufacturing
  process's yield and profitability are promptly
  addressed using pre-established decisions and
  data-driven rules. Through automation and data
  analytics, wafer yield management can effectively
  enhance the manufacturing process, increase
  yield, and maximize profitability.

Real Time Detection and Resolution of Yield Issues

• Benchmarking with other sites like Outsourced
  Semiconductor Assembly and Test (OSAT) providers
  is also a crucial aspect of wafer yield
  management. This helps to optimize and manage
  yield results from each site at the enterprise
  level, and track outsourced operations and
  supplier benchmarks such as foundries and OSATs.

7
Conclusion

• In summary, wafer yield management is critical in
  semiconductor data manufacturing. By optimizing
  manufacturing processes, tracking yield results,
  automating the tracking of test results and
  trends, detecting and resolving yield issues in
  real-time, and benchmarking with other sites,
  yield can be optimized, and profitability
  increased.
