Collaboration on the creation of a CONQ calculation can ensure that improvement initiatives are based on a viable foundation of data and collaboration. 552-560, October 1995. 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. in VLSI Systems, IEEE Computer Society Press 1995, pp. 638-658. [ya1] W. Maly, B. Trifilo, R.A. Hughes, and A.

Data mining tools are nowadays becoming more and more popular in the semiconductor manufacturing industry, and especially in yield-oriented enhancement techniques. as illustrated in [ce3] later. By setting up discussions where engineers can explore historic causes of yield loss, new levers can be discovered that will increase overall yield performance for a certain product or process. ICCAD 96 pp. According to the Integrated Circuit Engineering Corporation, yield is “the single most important factor in overall wafer processing costs,” as incremental increases in yield significantly reduce manufacturing costs.1 1. The percent of devices on the wafer found to perform properly is referred to as the yield. Teams can effectively link decisions from customer requirements (either by R&D or business units), down to bottom-line impact on front-end and back-end expected yield losses, to identify systemic root causes cutting across processes, reject categories, or products. 135-138, 1981. effect using capabilities available in commercial verification Analysis Tool for CMOS VLSI Circuits," Proceedings of the 1993 21-29. Test Structure for the Evaluation of Type Size and Density of By applying a holistic approach toward yield improvements based on the steps described above, a typical day in the life of a yield engineer improved in all three realms. fluctuations in process conditions and process corrective activities. 354-368, then has been developed in the subsequent papers. pp. 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. And yet many semiconductor players struggle to implement sustainable yield improvements due to ingrained mind-sets, an insufficient view of data, and isolated efforts as well as a lack of advanced-analytics capabilities. Merging these two views provides a full and readily approachable view of the cost of yield losses. Director and W.

H. Stapper, "Modeling of Integrated Circuit Defect Sensitivities", shifts in yield losses as measured by monetary impact, which helps prioritize the next wave of improvement initiatives. With so many factors in play, we see a lot of chip failures or defects.” Given its complexities, traditional quantitative analysis wouldn’t help fabs uncover all improvement opportunities, resulting in a lengthy process of root issue discovery—and thus massive yield losses. 512-526. which are not defect-based.

Therefore you should select the foundry the suits … Thus in the semiconductor industry, the risks to yield due to process variability and contaminations are ever increasing, as is the importance of continuously improving design and machine capabilities. Next, it can use a loss matrix to develop a holistic view of the company’s greatest sources of loss; then it can use that data to design more targeted initiatives that will have the biggest impact on increasing yield—and thus on improving the company’s bottom line. 135-142, June 1994. The semiconductor industry continues to push the edge of advancements in manufacturing. Annual SRC/ARPA CIM-IC Workshop, Aug. 1993. The key problems addressed by the Over the years, advances in fab technology such as more efficient air-circulation systems and better operator capabilities, as well as efforts to lessen direct human contact with the production process through the use of automation, have led to a decline in particulate problems.2 2.Jim Handy, “What’s it like in a semiconductor fab?”, Forbes, December 19, 2011, forbes.com.

ED-32, 356-390, 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. As noted by the CEO of advanced-analytics company Motivo Engineering, “Each fab has thousands of process steps, which, in turn, have thousands of parameters that can be used in different combinations. 4. The important step is to get individuals with a strong technical knowledge of data and database optimization to create the right data infrastructure to enable scale-up of analytics solutions.

Maly, "Modeling of Lithography Related Yield Losses for This approach reduced losses from material waste and customer quality issues while enhancing overall capacity (for example, dice output per day). The first step in ensuring that all functions are aligned in a yield transformation effort is to speak a common language—the cost of poor quality. 8. As our colleagues have noted, many analytics and machine-learning vendors believe that semiconductor companies prefer to develop solutions in-house, which discourages them from building strong relationships with other semiconductor players. Ferris-Prabhu, "Role of Defect Size Distributions 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.

IEEE Transactions of Semiconductor Manufacturing, pp. [m4] W. Maly, H.T. 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. 243-248, Sept. 1996. Yield engineers are further empowered with data to highlight potential opportunities to implement more yield gains by aligning or relaxing internal specifications, without affecting customer demand or satisfaction.

The uptick had not surpassed the upper control limit (UCL), so without the analysis there would have been no Due to the yield loss analysis, the manufacturer’s yield engineers could shift from a reactive “firefighting” stance on tackling ad hoc requests or manufacturing execution system triggers to solving for root causes of major excursions or other weekly yield losses on the line. As a result, semiconductor companies can more effectively implement systemic process changes and, particularly given the different cost structures for each product, result in significant and as yet unrealized cost savings. A percentage focus involves a bottom-up approach toward viewing yield percentages, either as an integrated view or by specific process areas. tab, Engineering, Construction & Building Materials, Travel, Logistics & Transport Infrastructure, McKinsey Institute for Black Economic Mobility.

Symposium The most important goal for any semiconductor fab is to improve the final product yields [ 4 ]. model using instead of the critical area the density of design International Test Conference, pp. Furthermore, many engineering and finance functions use different systems to track yield, which can result in constant disagreements or misalignment between the functions, rendering data less usable by the lack of agreement about which to use as the source of truth. This information is typically highly dependent upon the accuracy of the data captured by operators and made readily available for engineers through manufacturing execution systems. hereLearn more about cookies, Opens in new 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).
