摘要：An integrated circuit provided with ESD protection means comprising a silicon-controlled rectifier whose n-well (WLL), if the substrate (SBSTR) of the integrated circuitis of the p-type, is connected to the VDD supply instead of to the bonding-pad (BP) towhich electronic circuitry is connected. Consequently, the anode is only formed by the p+diffusion (d4) in the n-well (WLL). Therefore, negative voltages are allowed at thebonding pad (BP) because the junction is not forward-biased. Thus, an ESD protectiontowards the VSS is obtained. Additionally, a PMOST (MP) is used as an ESD protectiontowards the VDD.
