Introduction

JJF 1071-2010 "Rules for Writing National Metrology Calibration Standards" and JJF 1059.1-2012 "Uncertainty in Measurement" Degree Assessment and Representation together constitute a basic series of specifications supporting the compilation and revision of this specification. This calibration specification refers to GJB548B-2005 "Microelectronic Device Test Methods and Procedures", ANSI/ESD STM5.1-2007 "Electrostatic Discharge Sensitivity Test Human Body Model (HBM) Device Level", JESD22-A115C- 2010 "Electrostatic Discharge Sensitivity Test Machine Model (MM)" and JESD78E-2016 "Integrated Circuit Latch test". This specification is a revision of JJF 1238-2010 "Calibration Specification for Integrated Circuit Electrostatic Discharge Sensitivity Test Equipment" Order, the main revised content. --- Added machine model and latch model discharge calibration. ---Extend the human body discharge voltage calibration range from (500~8000)V to (100~8000)V. --- In the calibration of the human body model discharge parameters, the calibration of the discharge current parameters under a 500Ω load has been added. --- Revised the example of measurement uncertainty assessment.

The time required for the discharge current to decay from 100% peak to 36.8% peak. The reciprocal of the time interval tfr between the first zero-crossing point and the third zero-crossing point of the discharge current.

4 Overview

Integrated circuit electrostatic discharge sensitivity test equipment (also known as ESD equipment) mainly simulates the human body, The electrostatic voltage that may be carried by the machine, and the generated electrostatic voltage is applied to the device under test to investigate the antistatic voltage of the device. electrical capacity. According to the discharge mechanism, the integrated circuit electrostatic discharge sensitivity test equipment (hereinafter referred to as the tested equipment) can simulate human There are three discharge models of body, machine and latch. Among them, the human body model simulates the electrostatic discharge of electronic components after the human body is charged. Electricity, the machine model simulates the electrostatic discharge of electrostatic machines or equipment to electronic components, and the latch model simulates the electrostatic discharge of electronic components. The discharge caused to the device after the parasitic thyristor structure in the circuit is turned on. The short-circuit current waveform of the human body model discharge is shown in the figure 1, the short-circuit current waveform of the machine model discharge is shown in Fig. 2, and the voltage waveform of the latch model discharge is shown in Fig. 3 shown.
