Some implementations described herein include systems and techniques for fabricating a multi-dimension through silicon via structure in a three-dimensional integrated circuit device. The multi-dimension through silicon via structure includes a first columnar structure having a first width and a second columnar structure including a second width that is greater relative to the first width. The first columnar structure may include a low electrical capacitance and be configured for electrical signaling within the three-dimensional integrated circuit device. The second columnar structure may be configured to provide power to integrated circuitry of the three-dimensional integrated circuit device and also be configured to conduct heat through the three-dimensional integrated circuit device for thermal management of the three-dimensional integrated circuit device. Additionally, a pattern including the second columnar structure may be used for alignment purposes.
