Abstract

In this paper, we developed a numerical analysis model by using ADI-FDTD method to analyze three-dimensional interconnect structure. We discretized maxwell's curl equation by using ADI-FDTD. We introduced PML(Perfectly Matched Layer) absorbing boundary condition to solve the effect of the reflected wave at the interface. Evaluating the numerical model of PML and ADI-FDTD, we simulated the electric field distribution in time domain. We compare standard FDTD with ADI-FDTD, and analysis the result.

본 논문에서는 3차원 인터커넥트(3-D interconnect) 구조를 해석하기 위하여 ADI-유한차분시간영역(ADI-FDTD, Alternating Direction Implicit Finite Difference Time Domain)방법으로 맥스웰 회전방정식(Maxwell's curl equation)을 계산하는 수치 해석 모델을 개발하였다. 3차원 인터커렉트 모델내의 전자기파 문제를 해석하기 위하여 맥스웰 회전 방정식을 ADI-유한차분시간영역방법으로 이산화 하였으며, ADI-유한차분시간영역의 경계에서 발생하는 반사파를 해결하기 위하여 흡수 경계 조건인 완전 정합 층 방법(PML, Perfectly Matched Layer)을 도입하였다. 개발한 ADI-유한차분시간영역방법 및 완전 정합 층의 수치 모델을 검증하기 위하여 3차원 마이크로스트립 전송선(microstrip transmission line) 구조를 3차원 그리드(grid) 구조로 모델링한 후, 시간영역에서 전계 분포를 컴퓨터로 모의 실험하였다. 그리고 본 논문에서 제안한 ADI-유한차분시간영역방법과 종래의 스탠다드 유한차분시간영역방법의 수치적 성능을 정량적으로 비교, 분석하였다.
