  • Patent number: 11969752
    Abstract: The present invention discloses an organic polymer film and a manufacturing method thereof. The organic polymer film is mainly manufactured by the following steps. Firstly, the step (A) provides a xylene precursor and a substrate, and the step (B) places the substrate inside of a plasma equipment. After that, the step (C) evacuates the plasma equipment while introducing a carrier gas which carries vapor of the xylene precursor, and the step (D) turns on a pulse power supply system of the plasma equipment, generating a short pulse for plasma ignition. Finally, the step (E) forms the organic polymer film on the substrate. In the aforementioned steps, the frequency of the short pulse plasma is between 1 Hz˜10,000 Hz, and the pulse period of the short pulse plasma is between 1 ?s˜60 ?s.

  • Publication number: 20240088265
    Abstract: Techniques are provided herein to form semiconductor devices having epitaxial growth laterally extending between inner spacer structures to mitigate issues caused by the inner spacer structures either being too thick or too thin. A directional etch is performed along the side of a multilayer fin to create a relatively narrow opening for a source or drain region to increase the usable fin space for forming the inner spacer structures. After the inner spacer structures are formed around ends of the semiconductor layers within the fin, the exposed ends of the semiconductor layers are laterally recessed inwards from the outermost sidewalls of the inner spacer structures. Accordingly, the epitaxial source or drain region is grown from the recessed semiconductor ends and thus fills in the recessed regions between the spacer structures.

  • Publication number: 20240088217
    Abstract: Techniques are provided herein to form semiconductor devices that include a layer across an upper surface of a dielectric fill between devices and configured to prevent or otherwise reduce recessing of the dielectric fill. In this manner, the layer may be referred to as a barrier layer or recess-inhibiting layer. The semiconductor regions of the devices extend above a subfin region that may be native to the substrate. These subfin regions are separated from one another using a dielectric fill that acts as a shallow trench isolation (STI) structure to electrically isolate devices from one another. A barrier layer is formed over the dielectric fill early in the fabrication process to prevent or otherwise reduce the dielectric fill from recessing during subsequent processing. The layer may include oxygen and a metal, such as aluminum.
