INNOVATION IN YIELD IMPROVEMENT
… 2008 to December 2008. Methodology to solve low yield problems was presented. Then, innovative step-by-step methods for yield improvement for both systematic and "unknown" failures were evaluated. SWLY and SLLY were employed to enhance the yield for systematic failures. For "unknown" yield loss, …

Methodologies and tools for yield improvement of field-programmable logic architectures.
… (ITRS) predictions, controlling manufacturing yield is going to be a challenging task in future technologies. It was shown that the effective yield of the future field programmable gate arrays (FPGAs) will be too low to make a profit. Several FPGA yield improvement techniques have been proposed …

Yield Improvement in Eastern Soft Red Winter Wheat from 1919 to 2009
Periodic evaluation of improvements in yield and disease resistance is necessary to assess breeding progress over time, and the elucidation of underlying traits responsible for yield gains can help direct future breeding. Objectives of this study were: 1) to determine the rate and magnitude of …

The margin for yield improvement for no. 1 common 5/4 red oak in a conventional rough mill
This study examined the potential for improvement within a conventional (crosscut-first) rough mill. Improvement was measured in terms of volume and also value of cuttings produced. Current levels of yield were obtained from an in-plant yield study of 138 boards. The same material was then …
