The gate-source/drain parasitic capacitance is gradually dominating the total capacitance of the device, [5 – 8] and a FinFET structure with dual- k spacer will see the more deteriorated influences. In order to account for the change of the dual- k spacer, it is necessary to develop an accurately analytical capacitance model.
In order to account for the change of the dual- k spacer, it is necessary to develop an accurately analytical capacitance model. Several models have been reported. Liu et al. proposed a compact model of fringing capacitance for planar MOSFETs.
The different materials of spacer and ILD complicate the variety of the gate around parasitic capacitance. In order to achieve accurate modeling of , the two-layer structures must be thoroughly analyzed. , , , and are generalized to the vertical structure whose material boundaries adhere to the metal plates.
The ideal capacitor C s is influenced by the lead inductance L s (of the order of several nH) and the track resistance R s (typ. of the order of 20 mΩ … 100 mΩ, for cold electrolyte capacitors up to 1 Ω). At low frequencies the capacitive component predominates, at the self-resonant frequency the track resistance is measurable.
Not only does it cover the dual- k materials of ILD and spacer, but also it breaks the limitation in the previous capacitance model of dual- k materials. Moreover, only two fitting parameters are introduced. TCAD numerical simulations demonstrate the validation of our proposed model for FinFET parasitic capacitance.
For the multi-fin structure, the fringe capacitance of gate-to-source/drain is rewritten as where N is the number of fins, and is the parallel capacitance between two fins. Due to the multi-fins sharing the same raised S/D, the parallel-plate capacitors of and can be written as
