Microfluidic package design for magnetoresistive biosensors

In order for magnetoresistive biosensor technology to become a mainstream product for clinical and consumer use, several outstanding technical issues must be solved. This paper will focus on one of those issues, which is the need to adapt standard semiconductor packaging processes to fall within some biosensor fabrication process constraints. A set of materials and interconnection methods that meet these biosensor requirements are presented. The resulting architecture is compatible with laboratory assembly, but can be scaled up to small and medium manufacturing quantities by using larger 2-dimensional areas per production batch.
