Scalable Electrical Model and Performance Analysis of a Novel Bar TSV Structure

Article Preview

Abstract:

A novel Bar TSV(B-TSV) structure, formed by two semi-cylinders combining with a quadrangular is studied in this paper. This B-TSV structure extends the TSV design options by introducing new design parameters. The scalable electrical model of B-TSV is proposed and the effects of design parameters, such as the side length of quadrangular and the minimum distance between TSVs are investigated and concluded by a 3D electromagnetic solver. Performance comparison between B-TSV and the traditional cylindrical one is also provided by simulation under the Ground-Signal-Ground configuration. Simulation results show that B-TSV has better performance than the traditional one, and can be used to increase the TSV array density without degrading the electrical performance of TSV system.
