  • Publication number: 20230395647
    Abstract: Embodiments of present disclosure provide a MIM capacitor including a straining layer on an electrode, and a high-k dielectric layer formed on the straining layer. The straining layer allows the high-k dielectric layer to be highly crystallized without requiring an extra annealing process. The high crystallization of the high-k dielectric layer results in increased the dielectric value (k-value), thus, improving capacitance density in the MIM capacitor. Some embodiments provide a MIM capacitor device including stacked MIM capacitors with symmetrically arranged high-k dielectric layers and straining layers.

  • Patent number: 10998414
    Abstract: Methods for forming semiconductor structures are disclosed herein. An exemplary method includes forming a gate structure having a dummy gate stack over a substrate, performing a gate replacement process, such that the dummy gate stack is replaced with a metal gate stack, and forming a non-silane based oxide capping layer over the gate structure. The gate replacement process includes removing a portion of the dummy gate stack from the gate structure, thereby forming a gate trench. A work function layer is formed in the gate trench, a blocking layer is formed in the gate trench over the work function layer, and a metal layer (including, for example, aluminum) is formed in the gate trench over the blocking layer. The blocking layer includes titanium and nitrogen with a titanium to nitrogen ratio that is greater than one. In some implementations, the work function layer is formed over a dielectric layer.
