Patent ID: 7624001

Claim:
An analysis method of analyzing discharge in an information processing apparatus having a readable-writable storage device, wherein, when discharge simulation is performed at a node i on a first surface and a node j on a second surface of a simulation model, a calculating unit in the information processing apparatus incorporates a formula indicating relationship between potentials φi′ and φj′ at the node i and the node j after the discharge and a discharge starting voltage between the node i and the node j Vth(ij) as follows: φi′−φj′=α Vth(ij), where α denotes a coefficient indicating a ratio to the discharge starting voltage between the node i and the node j, and a formula indicating relationship between a charge Qi at the node i and a charge Qj at the node j before the discharge, and a charge Qi′ at the node i and a charge Qj′ at the node j after the discharge and an amount of charge movement Qij as follows: { Q i ′ = Q i - Δ ⁢ ⁢ Q ij Q j ′ = Q j + Δ ⁢ ⁢ Q ij into a formula given by discretizing a Poisson equation indicating relationship between a potential φ and a charge Q as follows: [ K 11 ⋯ K 1 ⁢ ⁢ m ⋮ ⋰ ⋮ K m ⁢ ⁢ 1 ⋯ K mm ] ⁢ { ϕ 1 ⋮ ϕ m } = { Q 1 ⋮ Q m } , so as to calculate and store in the storage device the amount of charge movement Qij due to the discharge and potential distribution after the discharge {φ1′, . . . φi′, . . . φj′, . . . φm}.
