Transmission line pulse method for measuring electrostatic discharge voltages

A method for measuring a parasitic series resistance which is introduced to modify the relationship between the transmission line pulse method and the human body model test method, comprising the steps of:

• determining a resistance of an intrinsic resistor which is used in human body model, wherein said resistance of the intrinsic resistor is set equal to a constant;
• measuring a first electrostatic discharge voltage by the human body model test method;
• measuring a second breakdown trigger current by the transmission line pulse method;
• and
• determining said parasitic series resistance by using a least square error solution method.

A method for determining a electrostatic discharge voltage derived from the transmission line pulse method, comprising the steps of:

• determining a resistance of an intrinsic resistor which is used in human body model, wherein said resistance of the intrinsic resistor is usually set equal to a constant;
• measuring a first electrostatic discharge voltage by the human body model test method;
• measuring a second breakdown trigger current by the transmission line pulse method;
• determining a parasitic series resistance by using a least square error solution method, wherein said parasitic series resistance is introduced to modify the relationship between the transmission line pulse method and the human body model test method;
• and
• determining a second electrostatic discharge voltage derived from the transmission line pulse method by multiplying said second breakdown trigger current by a sum of said resistance of the intrinsic resistor and said parasitic series resistance.
