  • In this paper, we analyzed the breakdown voltage and on-resistance of the multi-RESURF SOI LDMOSFET as a function of epi-layer concentration. P-/n-epi layer thickness and doping concentration of the proposed structure are varied from $2{\sim}5{\mu}m\;and\;1\{times}10^{15}/cm^{3}^{\sim}9\{times}10^{15}/cm^{3}$ to find optimum breakdown voltage and on-resistance of the proposed structure. The maximum breakdown voltage of the proposed structure is $224\;V\;at\;R_{on}=0.2{\Omega}-mon^{2}\;with\;P_{epi}=3\{times}10^{15}/cm^{3},\;N_{epi}=7\{times}10^{15}/cm^{3}\;and\;L_{epi}=10{\mu}m$. Characteristics of the device are verified by two-dimensional process simulator ATHENA and device simulator ATLAS.
