  • Patent number: 11876122
    Abstract: A method of forming a semiconductor device. A substrate having a fin structure is provided. A dummy gate is formed on the fin structure. A polymer block is formed adjacent to a corner between the dummy gate and the fin structure. The polymer block is subjected to a nitrogen plasma treatment, thereby forming a nitridation layer in proximity to a sidewall of the dummy gate under the polymer block. After subjecting the polymer block to the nitrogen plasma treatment, a seal layer is formed on the sidewall of the dummy gate and on the polymer block. An epitaxial layer is then grown on a source/drain region of the fin structure. The dummy gate is then replaced with a metal gate.

  • Patent number: 11830961
    Abstract: A germanium-on-silicon photodetector is fabricated by forming a thin silicon oxide layer on a silicon layer, and then forming a silicon nitride layer on the silicon oxide layer. A nitride dry etch process is used to etch an opening through the silicon nitride layer (through a photoresist mask). The nitride dry etch is stopped on the thin silicon oxide layer, preventing damage to the underlying silicon layer. A wet etch is then performed through the opening in the silicon nitride layer to remove the exposed silicon oxide layer. The wet etch exposes (and cleans) a portion of the underlying silicon layer. High-quality germanium is epitaxially grown over the exposed portion of the silicon layer, thereby providing a germanium structure that forms the intrinsic region of a PIN photodiode.
