Classification: CPC G | IPC G

Claim 15:
16. A method for evaluating a heat sensitive structure, comprising:
identifying a heat sensitive structure in an integrated circuit design layout;
identifying a FinFET structure in the integrated circuit design layout;
calculating an operating temperature of the FinFET structure by taking a practical current distribution into consideration; and
calculating an anticipated temperature increase for the heat sensitive structure induced by thermal coupling of the FinFET structure at the operating temperature,
wherein calculating the operating temperature of the FinFET structure by taking the practical current distribution into consideration comprises:
determining a total current running through the FinFET structure, a polysilicon gate (PO) number of the FinFET structure, a polysilicon gate over diffusion edge (PODE) number of the FinFET structure, a source number of the FinFET structure, and a drain number of the FinFET structure.
