Latest Patents

One of Cheong Min Hong's latest patents is the "Fingered capacitor with low-k and ultra-low-k dielectric layers." This innovative design features an integrated circuit that incorporates a fingered capacitor with multiple metal fingers formed in inverted-trapezoid-shaped trenches. The multi-layer structure includes a polish stop layer over an ultra-low-K dielectric layer, which is situated above a low-K dielectric layer and a dielectric cap layer. The ultra-low-K dielectric layer plays a crucial role in reducing capacitance variations between the fingers, while the polish stop layer prevents metal height variations that could arise from performing chemical mechanical polishing (CMP) directly on the ultra-low-K dielectric layer. Additionally, the layered structure may include another low-K dielectric layer over the polish stop layer, providing a soft landing for the CMP. After the CMP polishing, the polish stop layer can be removed, allowing for the formation of another ultra-low-K dielectric layer that encapsulates the tops of the metal fingers.
