Abstract
A thermocompression bonding (TCB) apparatus can include a wall having a height measured in a first direction and configured to be positioned between a first pressing surface and a second pressing surface of a semiconductor bonding apparatus. The apparatus can include a cavity at least partially surrounded by the wall, the cavity sized to receive a semiconductor substrate and a stack of semiconductor dies positioned between the semiconductor substrate and the first pressing surface, the stack of semiconductor dies and semiconductor substrate having a combined unpressed stack height as measured in the first direction. In some embodiments, the unpressed stack height is greater than the height of the wall, and the wall is configured to be contacted by the first pressing surface to limit movement of the first pressing surface toward the second pressing surface during a semiconductor bonding process.
