The type 2 dielectric film has been routinely used in transistors, such as TFTs. A thick layer is used to prevent the top-to-bottom metal shortage, which is a killing factor for the yield.

Both cases of the Hk-MOSFET hexagonal cell, one with a semiconductor in the center of each hexagonal cell and another with an insulator in the center, are discussed.
WebMOSFETs are good for higher voltage ratings since on-resistance is dominated by epi-layer resistance and high cell density is not beneficial. The basic MOSFET operation is the same for both structures. Unless specified, the N-channel trench MOSFET is discussed in this application note. Figure 1a: Trench MOSFET Structure N+ P-body N-Epi N+ Substrate WebGate MOSFET with high k-spacer (HfO 2). The impact of gate underlap and overlap on the DC and RF performance of JL- DG MOSFET is analyzed with the help of a numerical TCAD device simulator. We engage Transconductance (g m), Cut-Off Frequency (f T), Total capacitance (C gg), Miller capacitance as the key figure of merits for the analysis.
