  • Patent number: 12113057
    Abstract: A physical layout of a symmetric FET is described which provides symmetry in voltages coupled to structures of the FET so to reduce OFF state asymmetry in capacitances generated by the structures when the FET is used as a switch. According to one aspect, the symmetric FET is divided into two halves that are electrically coupled in parallel. Gate structures of the two half FETs are arranged in the middle region of the layout, each gate structure having gate fingers that project towards opposite directions. Interdigitated source and drain structures run along the gate fingers and include crossover structures that cross source and drain structures in the middle region of the layout. The gate structures share a body contact region that is arranged in the middle of the layout between the two gate structures.

  • Patent number: 12080599
    Abstract: Methods and improved process flows are provided herein for forming self-aligned contacts using spin-on silicon carbide (SiC). More specifically, the disclosed methods and process flows form self-aligned contacts by using spin-on SiC as a cap layer for at least one other structure, instead of depositing a SiC layer via plasma vapor deposition (PVD), chemical vapor deposition (CVD), atomic layer deposition (ALD), etc. The other structure may be a source and drain contact made through the use of a trench conductor. By utilizing spin-on SiC as a cap layer material, the disclosed methods and process flows avoid problems that typically occur when SiC is deposited, for example by CVD, and subsequently planarized. As such, the disclosed methods and process flows improve upon conventional methods and process flows for forming self-aligned contacts by reducing defectivity and improving yield.
