Latest Patents

One of Yang-Chun Cheng's latest patents is titled "Dual metal gate structures on nanoribbon semiconductor devices." This patent describes techniques for forming semiconductor devices that utilize different work function metals over various devices. These techniques are particularly beneficial for gate-all-around (GAA) transistors. In this innovation, neighboring semiconductor devices are designed with distinct work functions to serve as the gate electrodes for each device. For instance, a p-channel GAA transistor may incorporate a specific work function metal, while an adjacent n-channel GAA transistor utilizes a different work function metal, ensuring that there is no overlap between the two.

Another significant patent by Cheng is "Self-aligned lateral contacts." This patent outlines methods for creating self-aligned lateral contacts in transistors. In this example, a first trench contact interfaces with a source or drain region of a transistor. The second trench contact consists of non-contiguous portions that are co-planar with the first trench contact and the gate structure. The design allows for a sidewall of the second trench contact to be self-aligned with the first trench contact, optimizing the overall structure and functionality of the transistor.
