The method involves experimental design and principal components analysis to identify which parameters appear to be important and which are irrelevant, so that they can be fixed at some reasonable value and omitted from further considerations. When the principal parameters have been chosen, regression techniques are used to obtain models that approximate the performance of the analog integrated circuit. The constructed models have enough information to find the circuit fault when it is tested.","PeriodicalId":253336,"journal":{"name":"1999 4th International Workshop on Statistical Metrology (Cat.

The ULSI manufacturing process faces CD variation as a new issue (Pforr et al., 1995). Two major factors of CD variation are process variation and the optical proximity effect, which depends on the pattern layout. Hence, statistical gate CD control considering the CD variation caused by these two factors is a key issue in the ULSI manufacturing process. In this paper, we describe the RSF with variable coefficients for CD variation analysis, including mask bias OPC (optical proximity correction). The RSF with variable coefficients to lens conditions NA and /spl sigma/ is newly developed, indicating the nonlinear dependence of CD on the focus position. This approach allows CD variation analysis including mask bias OPC, even when the line width comes close to the stepper wavelength.","PeriodicalId":253336,"journal":{"name":"1999 4th International Workshop on Statistical Metrology (Cat.

As the size of active repeaters decreases, the utilization of dense buffering schemes, up to complete replacement of metal wiring with active devices, has been proposed in order to realize efficient and noise-immune clock distribution networks. However, local variance of MOSFET electrical parameters, such as V/sub T/ and I/sub DSS/, increases with scaling of device dimensions, thus causing large intra-die variability of the timing properties of clock buffers. As a consequence, we expect local mismatch to be a significant source of clock skew in deep sub-micron technologies. In order to accurately verify this assumption, we applied advanced statistical simulation techniques and accurate mismatch characterization data to the statistical simulation of relatively small clock distribution networks. The comparison with Monte Carlo simulations performed by neglecting the mismatch effect confirmed that it is necessary to account for local device variations in the design and sizing of the clock distribution network.","PeriodicalId":253336,"journal":{"name":"1999 4th International Workshop on Statistical Metrology (Cat.

For high S/N inspection, (1) reduction of noise signals from embedded particles, and (2) improvement in sensitivity are the objectives. Optimal selection of the incident-light angle of the laser tool, polarization of the scattered light, and optimized sample structures enable us to achieve the objectives. By applying the new high S/N inspection method, a new insight has been found, i.e. total defect count is in proportion to defect size (threshold value) with the rule of power of -6, which is much larger than the conventional value of -2. Among the killer defects, pits mainly increase very rapidly with the decrease in size. The slope is approximately -7 in the log(count)-log(size) plot.","PeriodicalId":253336,"journal":{"name":"1999 4th International Workshop on Statistical Metrology (Cat.

This is particularly the case for the silicon oxidation model, which is involved in numerous fundamental steps of an industrial process. In this work, using the response surface methodology, a viscoelastic oxidation model has been calibrated on a wide range of process conditions which has allowed the optimization of LOCOS type isolation structures for a 0.35 /spl mu/m CMOS technology.","PeriodicalId":253336,"journal":{"name":"1999 4th International Workshop on Statistical Metrology (Cat.

Traditionally, the device variability has been the dominant source. It is believed that with continuing technology scaling into the deep sub-micron regime, the interconnect constitutes an increasing portion of the overall circuit delay, and variability. In this paper, we analytically investigate the delay variability composition for an advanced 0.18 /spl mu/m CMOS technology, accounting for the significant intra-field variability. A more realistic model to estimate the variance of global interconnect lines is proposed. The results indicate that the device variability of good designs contributes about 90% of the overall variability.","PeriodicalId":253336,"journal":{"name":"1999 4th International Workshop on Statistical Metrology (Cat.
