Abstract: A method of patterning a semiconductor device includes following steps. First of all, a substrate is provided, and a first target pattern is formed in the substrate. Next, a second target pattern is formed on the substrate, across the first target pattern. Then, a third pattern is formed on a hard mask layer formed on the substrate, by using an electron beam apparatus, wherein two opposite edges of the third pattern are formed under an asymmetry control.

Abstract: A method for fabricating a semiconductor device includes the steps of forming a metal-oxide semiconductor (MOS) transistor on a substrate, forming an interlayer dielectric (ILD) layer on the MOS transistor, forming a ferroelectric field effect transistor (FeFET) on the ILD layer, and forming a ferroelectric random access memory (FeRAM) on the ILD layer. The formation of the FeFET further includes first forming a semiconductor layer on the ILD layer, forming a gate structure on the semiconductor layer, and then forming a source/drain region adjacent to the gate structure.
