Patent attributes
A method of manufacturing a semiconductor device structure includes forming a bond or joint between a first device and a second device. The first device comprises an integrated passive device (IPD) and a first contact pad disposed over the IPD. The second device comprises a second contact pad. The first contact pad has a first surface with first lateral extents. The second contact pad has a second surface with second lateral extents. The width of the second lateral extents is less than the width of the first lateral extents. The joint structure includes the first contact pad, the second contact pad, and a solder layer interposed therebetween. The solder layer has tapered sidewalls extending in a direction away from the first surface of the first contact pad to the second surface of the second contact pad. At least one of the first surface or the second surface is substantially planar.
