WAFER YIELD MANAGEMENT
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.
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.
