Abstract
Fabrication of mechanically stable interconnections on chip and micro-systems, applicable in hazardous environment, is the
main objective of the device packaging techniques. Isothermal solidification based interconnection technique offers
possibility of obtaining high mechanical stability of bonding. Seal rings, commonly fabricated at input opening of sensors,
are developed using Sn interlayer metal. Effects of temperature, reaction time, pressure, thickness and geometry on the
ultimate tensile strength (UTS), ultimate shear strength (USS) and ultimate torsional strength values are analyzed and
reported..
Keywords
