Abstract : Significant progress was made in the process improvement work. A molybdenum disk was introduced in the solder joint. Test data shows that the failure mode due to silicon pellet cracking was eliminated. Two new pellet designs were used and some devices with the new pellets were evaluated. It was found that the round pellet resulted in satisfactory pellet yield and device yield. (Author)
