In this era of electronics miniaturization, high yield and low-cost integrated circuit (IC) substrates play a crucial role by providing a reliable method of high density interconnection of chip to board. In order to maximize substrate real-estate, the distance between Cu traces also known as line and space (L/S) should be minimized. Typical PCB technology consists of L/S larger than 40 µ whereas more advanced wafer level technology currently sits at or around 2 µm L/S. In the past decade, the chip size has decreased significantly along with the L/S on the substrate. The decreasing chip scales and smaller L/S distances has created unique challenges for both printed circuit board (PCB) industry and the semiconductor industry. Fan-out panel-level packaging (FOPLP) is a new manufacturing technology that seeks to bring the PCB world and IC/semiconductor world even closer. While FOPLP is still an emerging technology, the amount of high-volume production in this market space provide a financial incentive to develop innovative solutions in order to enable its ramp up. The most important performance aspect of the fine line plating in this market space is plating uniformity or planarity. Plating uniformity, trace/via top planarity, which measures how flat the top of the traces and vias are a few major features. This is especially important in multilayer processing, as nonuniformity on a lower layer can be transferred to successive layers, disrupting the device design with catastrophic consequences such as short circuits. Additionally, a non-planar surface could also result in signal transmission loss by distortion of the connecting points, like vias and traces. Therefore, plating solutions that provide a uniform, planar profile without any special post treatment are quite desirable.

Isotropic conductive adhesives are typically silver filled epoxy resins. Electronics assemblers have evaluated these materials for a variety of unique interconnect applications. The goal is a conductive polymer that exhibits similar reliability and performance to traditional solder while offering the benefits of a polymer structure such as low temperature processing and good thermal stability as well as the ability to bond a variety of substrates.
