As a result, more simultaneous switching noise (SSN) is observed. However, SSN analysis requires the modeling of power and ground planes. The PEEC (Partial Element Equivalent Circuit) method is often used for modeling the planes but it suffers from a large amount of computation time and the limited size of PCB it can handle. This paper proposes a new fast method of generating an equivalent circuit networks for multi-layer packages and PCBs. A library of parasitics is built for different vertical structures and materials by using a electromagnetic field solver. This library is used to generate the equivalent circuit without the need for the complex field solving procedure. Compared to the conventional method (PEEC), the proposed method drastically reduces the time and effort for generating the equivalent circuit model with the same accuracy. This method has been used to design a variety of high speed memory module products.","PeriodicalId":13415,"journal":{"name":"ICVC '99. 6th International Conference on VLSI and CAD (Cat.

This technique utilizes the oxide rounding and, thus, effectively suppresses the inverse narrow width effect due to the stress reduction at the top corner and the less interface influence between active and field oxide. Also this technique showed no degradation of junction leakage current and less profile micro-loading effect compared with the conventional resist mask process. As a result, it has been found that this technique is very effective for sub-0.15 /spl mu/m STI formation.","PeriodicalId":13415,"journal":{"name":"ICVC '99. 6th International Conference on VLSI and CAD (Cat.

Although somewhat resolved, we must consider the specifications of CD control for next generation devices such as design rules of 0.15 /spl mu/m. We evaluate the printability of the half-tone phase shift mask with i-line and KrF steppers after defect repair. We also confirm the accuracy of edge repair, Ga+ deep implantation effects and the environmental stability of FIB and blue laser repair tools.

We propose to study the interaction between various cost functions in placement. In particular, we will consider, net-cut, wire-length, congestion, and timing. We show that minimizing wire-length may (and in general, will) create locally congested regions. We demonstrate that most other congestion related objectives are ill behaved and they should only be used in a post processing step. Using a post processing stage is found to be more effective than optimizing the congestion in one step. For the relationship between wire-length and net-cut, we demonstrate that they are correlated differently in different hierarchical levels.","PeriodicalId":13415,"journal":{"name":"ICVC '99. 6th International Conference on VLSI and CAD (Cat.

The result of the ray tracing simulation showed the improvement in cohesivity of light at the photodiode as well. However, the high refractive index of the passivation layer caused high reflection at the surface and hence a decrease in sensitivity. Moreover, with the use of ARL (Anti Reflection Layer) to control the high reflection at the Si substrate, the increase in the refractive index of ARL brought about the increase in sensitivity due to the low reflection at the Si substrate.","PeriodicalId":13415,"journal":{"name":"ICVC '99. 6th International Conference on VLSI and CAD (Cat.
