Abstract: A method of manufacturing a semiconductor device is provided. The method includes forming a first trench partially through a first substrate from a first side of the first substrate. The method also includes widening a bottom portion of the first trench to form a lateral footing area of the first trench. The method includes forming a first metallization in the first trench; forming a second trench through a second substrate from a second side of the second substrate to expose at least a portion of first metallization in an area corresponding to the lateral footing area of the first trench, the second side being opposite to the first side. The method also includes forming a second metallization in the second trench in contact with the first metallization.
