Abstract
A semiconductor device includes a memory circuit and a logic circuit. The memory circuit includes a word line, a bit line, a common line and a memory transistor having a gate coupled to the word line, a drain coupled to the bit line and a source coupled to the common line. The logic circuit includes a field effect transistor (FET) having a gate, a drain and a source. The memory transistor has a gate electrode layer formed on a gate dielectric layer, and the gate dielectric layer includes a first insulating layer and a first ferroelectric (FE) material layer. The FET has a gate electrode layer formed on a gate dielectric layer, and the gate dielectric layer includes a second insulating layer and a second FE material layer.
