In this paper, Self-Heating Effect (SHE) according to depth of STI was analyzed and STI thickness optimization was performed in the plate-shaped vertical field effect transistor (VFET). In case of a VFET, the path of leakage current (Ioff) is different from that of a lateral FET (LFET). Asa result, Ioff of VFET is not influenced by STI depth. For this reason, the STI depth of the VFET is not needed...
Self-heating effects (SHEs) were studied on the vertical nanoplate-shaped gate-all-around (GAA) FETs (vNPFETs) as a target of 5nm node technology. The thermal properties are compared between face-up and face-down configuration. Decreasing the channel width is vulnerable to both configurations in terms of SHEs due to the reduced area of heat dissipation. It is well known that the SHE is alleviated...
In this paper, the Self-Heating Effects in Vertical FETs(VFET) have been investigated according to device geometry. It is demonstrated that the temperature of the device increases by using a low-k dielectric and an air gap between the metal lines. In addition, when air spacers are used, the lattice temperature is further increased and the on current reduction ratio increases compared to the common...
