  • Patent number: 10504788
    Abstract: An inverter structure includes a first fin structure and a second fin structure respectively disposed within a P-type transistor region and an N-type transistor region on a substrate. Agate line is disposed on the substrate. A first end of the gate line is within the P-type transistor region, and a second end of the gate line is within the N-type transistor region. Two dummy gate lines are disposed at two sides of the gate line. Each dummy gate line has a third end within the P-type transistor region, and a fourth end within the N-type transistor region. A distance between the first end and the first fin structure is greater than a distance between the third end and the first fin structure. The distance between the second end and the second fin structure is smaller than a distance between the fourth end and the second fin structure.

  • Patent number: 10475738
    Abstract: A semiconductor device preferably includes: a first metal-oxide semiconductor (MOS) transistor on a substrate; a first ferroelectric (FE) layer connected to the first MOS transistor; a second MOS transistor on the substrate; and a second FE layer connected to the second MOS transistor. Preferably, the first FE layer and the second FE layer include different capacitance.
