The development of IC technology is driven by the need to increase performance and functionality while reducing size, power and cost. The continuous pressure to meet those requirements has created innovative, small, cost-effective 3-D packaging technologies. 3-D packaging can offer significant advantages in performance, functionality and form factor for future technologies. Breakthrough in wafer level packaging using through silicon via technology has proven to be technologically beneficial. Integration of several key and challenging process steps with a high yield and low cost is key to the general adoption of the technology. This paper will outline the breakthroughs in cost associated with an iTSV or Via-Mid structure in a integrated process flow. Key process technologies enabling 3-D chip:Via formationInsulator, barrier and seed depositionCopper filling (plating),CMPWafer thinningDie to Wafer/chip alignment, bonding and dicing This presentation will investigate these techniques that require interdisciplinary coordination and integration that previously have not been practiced. We will review the current state of 3-D interconnects and the of a cost effective Via-first TSV integrated process.

Abstract The need to increase transistor packing density beyond Moore's Law and the need for expanding functionality, realestate management and faster connections has pushed the industry to develop complex 3D package technology which includes System-in-Package (SiP), wafer-level packaging, through-silicon-vias (TSV), stacked-die and flex packages. These stacks of microchips, metal layers and transistors have caused major challenges for existing Fault Isolation (FI) techniques and require novel non-destructive, true 3D Failure Localization techniques. We describe in this paper innovations in Magnetic Field Imaging for FI that allow current 3D mapping and extraction of geometrical information about current location for non-destructive fault isolation at every chip level in a 3D stack.

Wafer Level Packaging

The wafer-level packaging process is an important technology used in semiconductor manufacturing, and how to effectively control this manufacturing system is thus an important issue for packaging firms. One way to aid in this process is to use a forecasting tool. However, the number of observations collected in the early stages of this process is usually too few to use with traditional forecasting techniques, and thus inaccurate results are obtained. One potential solution to this problem is the use of grey system theory, with its feature of small dataset modeling. This study thus uses the AGM(1,1) grey model to solve the problem of forecasting in the pilot run stage of the packaging process. The experimental results show that the grey approach is an appropriate and effective forecasting tool for use with small datasets and that it can be applied to improve the wafer-level packaging process.
