Resolution enhancement in advanced optical lithography will reach a new plateau of complexity at the 32 nm design rule manufacturing node. In order to circumvent the fundamental optical resolution limitations, ultra low k1 printing processes are bein

The overlay budgets in leading-edge processes are expected to shrink below 20nm within the next 12-24 months. The demand for ever higher accuracies of overlay metrology for the 65nm node and below drive the development and design of new optical metro

We have developed a method for calculating the statistical effects of spatial noise on the overlay measurement extracted from a given overlay target. The method has been applied to two kinds of overlay targets on three process layers, and the new met

While overlay precision has received much focus in the past, overlay accuracy has become more significant with shrinking process budgets. One component of accuracy is the difference between pre-etch (DI) and post-etch (FI) overlay, which is a functio

As overlay budgets shrink with design rules, the importance of overlay metrology accuracy increases. We have investigated the overlay accuracy of a 0.18mm design rule Copper-Dual-Damascene process by comparing the overlay metrology results at the Aft

In order to control and minimize overlay metrology errors, we have to deal with a number of design parameters both in the metrology tool domain and in the overlay target domain. For enhancing the rate of performance improvement vs. technology investm

The continuing demand for higher frequency microprocessors and larger memory arrays has led to decreasing device dimensions and smaller process control windows. Decreasing process control windows have created a need for higher precision metrology to

Bright field optical microscopy has well-known nonlinearity problems due to varying film thickness. Phase images eliminate many of these problems. This paper will describe the advantages of phase imaging, based on calculated results. Experimental cor
