Semiconductor device having ESD protection circuit with time delay

A semiconductor device comprising:

• an internal circuit disposed on a substrate;
• an input/output pad connected between a lead for external contact and the internal circuit;
• an input/output signal line that connects the input/output pad and the internal circuit;
• a junction resistor located in the input/output signal line between the input/output pad and the internal circuit;
• and
• a capacitor, also located on the input/output signal line between the input/output pad and the internal circuit, including a first electrode comprising the junction resistor and a second electrode connected to a power supply line.
