Looking at yield percentages only provides one view of the situation; engineering and finance alike must align on using the cost of poor quality as the method for understanding and guiding the direction of the company’s yield improvement efforts.

Indeed, the celebrated percentage increases may or may not lead to any significant impact on the bottom line. Once the biggest loss areas are identified using the loss matrix, it is important to ensure the resulting improvement activities are sustainable; this starts by isolating the products that are the biggest contributors to scrap (Exhibit 3). 19-27.

Armed with end-to-end traceability of yield losses from front end to back end, yield teams benefit from a more granular view of bottom-line impact, reducing the analytical resources needed and allowing for more insights to be shared with the cross-functional team, including R&D, business-unit sales and marketing teams, and front- and back-end managers.

Domain," In Proceedings of Defect and Fault Tolerance in VLSI [ce4] and [ce5] describe the critical area extraction methodology critical areas from the gate-level netlist. Our experience working in Asia shows that a differentiating factor to effectively manage increasing cost pressures and sustain higher profitability is improving end-to-end yield—encompassing both line yield (wafers that are not scrapped) and die yield (dice that pass wafer probe testing). (as a measure of defect sensitivity). The key problems addressed by the Computer-Aided Defect Diagnosis," IEEE Transactions on Semiconductor In particular to yield, issues always cross sites and require end-to-end collaboration to get breakthrough results.

Given the fast-changing environment and highly specialized capability in analytics, ongoing collaboration and partnership will help semiconductor players stay on the cutting edge and employ solutions that enhance in-house capability. While organizing loss categories along these lines, semiconductor companies should also analyze which rejects are true and which are false, as well as discuss what potential cross-functional collaborations may help solve the issue.

This per-product analysis ensures that action is taken only on items that have the biggest impact on yield.

Engineers can now identify key losses as per the loss matrix that are unaddressed and start with the one that will have the biggest forecasted impact to the bottom line. Also very frequently the IEEE Design and Test of Computers, vol. Subscribed to {PRACTICE_NAME} email alerts. Yield improvements should address excursion cases—but more important, they should also tackle the baseline yield. Excursion—that is, when a process or piece of equipment moves out of preset specifications—can be a significant contributor to yield loss, particularly if it goes undiscovered until after fabrication. Furthermore, semiconductor manufacturing is in a unique position compared with other industries to reap the benefits of advanced analytics given the massive amount of data embedded in fabs’ highly automated and sensor-laden environment.

Stapper, "Modeling of Integrated Circuit Defect Sensitivities", pp. Internal problem solving is further strengthened with the help of big data analytics solutions that proactively highlight commonalities or pattern recognition—for example, a particular tool, process group, or even upstream product or process that contributes significantly to yield losses (see sidebar, “The role of advanced analytics in semiconductor yield improvement: Converting data into actions”). 3-6, Oct. 1997. Production volumes need to be … Traditionally, yield is the proportion of correct items (conforming to specifications) you get out of a process compared to the number of raw items you put into it. Along with development of four analytical tools and a performance management dashboard, this yield PMO has delivered 10 percent yield improvement and identified and implemented $12 million cost savings opportunity within six months. At one manufacturer, yield engineers’ daily activities ranged across three main areas—root-cause problem solving of excursions and other critical identified yield losses, cross-functional yield improvement activities and collaborations with other teams, and operational tracking and reporting of yield performances across the fab. Once the front-end process has been completed, the semiconductor devices or chips are subjected to a variety of electrical tests to determine if they function properly. Please use UP and DOWN arrow keys to review autocomplete results. of IEEE International Using the loss matrix and analytical solutions—where costs can be easily viewed by processes, reject codes, or products—allows engineers and managers to gain a better view of the health of the entire manufacturing process, from R&D through wafer fabrication and die packaging, to push [dm3] J.
