Layer Assignment for Yield Enhancement 1
نویسنده
چکیده
In this paper, two algorithms for layer assignment with the goal of yield enhancement are proposed. In the rst, vias in an existing layout are moved in order to decrease its sensitivity to defects. A greedy algorithm for achieving this objective is presented. In the second, we formulate the layer assignment problem as a network bipartitioning problem. By applying the primal-dual algorithmm1] (a variation of the Kernighan-Lin algorithmm2]), the objective of critical area minimization can be achieved. These two methods are applied to a set of benchmark circuits to demonstrate their eeectiveness.

The effect of single and double-layer anti-reflective coatings on efficiency enhancement of silicon solar cells was investigated. The reflectance of different anti-reflection structures were calculated using the transfer matrix method and then to predict the performance of solar cells coated by these structures, the weighted average reflectance curves were used as an input of a PC1D simulation....
متن کاملA Novel Protection Guaranteed, Quality of Transmission Aware Routing and Wavelength Assignment Algorithm for All-optical Networks
Transparent All Optical Networks carry huge traffic and any link failure can cause the loss of gigabits of data; hence protection and its guarantee becomes necessary at the time of failure. Many protection schemes were presented in the literature, but none of them speaks about protection guarantee. Also, in all optical networks, due to absence of regeneration capabilities, the physical layer i...

© 2012 ETRI Journal, Volume 34, Number 3, June 2012 Three-dimensional (3D) memories using through-silicon vias (TSVs) will likely be the first commercial applications of 3D integrated circuit technology. A 3D memory yield can be enhanced by vertical redundancy sharing strategies. The methods used to select memory dies to form 3D memories have a great effect on the 3D memory yield. Since previou...
متن کاملTopological Optimization of PLAs
Several topological optimization techniques have been developed to minimize the area of PLAs. Significant yield enhancement can also be achieved by minimizing the defect sensitivity of a design that is already optimized for area. In this paper, we propose a yield enhancement technique through which the defect sensitivity of the design will be minimized without increasing the area. This reductio...
