In one general aspsect, a semiconductor device can include at least a first device region and a second device region disposed at a surface of a semiconductor region where the second device region is adjacent to the first device region and spaced apart from the first device region. That semiconductor device can include a connection region disposed between the first device region and the second device region, and a trench extending into the semiconductor region and at least extending from the first device region, through the connection region, and to the second device region. The semiconductor device can include a dielectric layer lining opposing sidewalls of the trench, an electrode disposed in the trench, and a conductive trace disposed over a portion of the trench in the connection region and electrically coupled to a portion of the electrode disposed in the connection region.
