Latest Patents

C Alexander Ernst holds a patent titled "Method for 3D ink jet TCB interconnect control." This patent describes a semiconductor device, semiconductor device assembly, and a method of forming a semiconductor device assembly that includes a barrier on a pillar. The assembly features a semiconductor device positioned over another semiconductor device, with at least one pillar extending from one device towards a pad on the other. The barrier on the exterior of the pillar serves as a standoff to control the bond line between the semiconductor devices. This innovation aims to reduce solder bridging and prevent reliability and electromigration issues that can arise from intermetallic compound (IMC) formation between the solder and copper portions of a pillar. Additionally, the barrier assists in aligning the pillar with a pad during assembly, minimizing misalignment due to lateral movement of the devices. Windows or slots in the barrier allow for the expansion of solder in specific directions while preventing bridging in others.
