Abstract:
1. A semiconductor structure comprising: an insulating layer having a first surface and a second surface opposite the first surface; a thermal insulating element extending vertically through the insulating layer from the first surface to the second surface, the thermal insulating element and the insulating layer comprising different insulating materials and the thermal insulating element comprising a thermal insulating material; a first conductor on the second surface of the insulating layer and immediately adjacent to the thermal insulating element; a solder bump on the first conductor; a second conductor extending vertically through the insulating layer from the first surface to the second surface such that the second conductor is immediately adjacent to the first conductor and to the insulating layer and such that a portion of the insulator layer is positioned laterally between the second conductor and the thermal insulating element; and a third conductor on the first surface of the insulating layer and immediately adjacent to the thermal insulating element and the second conductor, the thermal insulating element being narrower in width than the first conductor and reducing thermal energy transfer during a chip-join process from the solder bump to a metal level in the semiconductor structure.
