The HBM is a component level stress developed to simulate the action of a human body discharging accumulated static charge through a device to ground, and employs a series RC network consisting of a 100 pF capacitor and a 1500 Ohm resistor. Three major stress methods are widely used in the industry today to describe uniform methods for establishing ESD withstand thresholds (highest passing level). Standards are developed to enhance the quality and reliability of ICs by ensuring all devices employed have undergone proper ESD design and testing, thereby, minimizing the detrimental effects of ESD. ESD can occur in any one of four different ways: a charged body can touch an IC, a charged IC can touch a grounded surface, a charged machine can touch an IC, or an electrostatic field can induce a voltage across a dielectric sufficient to break it downĮSD can have serious detrimental effects on all semiconductor ICs and the system that contains them. When a static charge moves, it becomes a current that damages or destroys gate oxide, metallization, and junctions. It can occur only when the voltage differential between the two surfaces is sufficiently high to break down the dielectric strength of the medium separating the two surfaces. ESD is a miniature lightning bolt of charge that moves between two surfaces that have different potentials. When a static charge moves from one surface to another, it becomes ESD. This results in an unbalanced electrical condition known as static charge. One surface gains electrons, while the other surface loses electrons. Typically, it is created by insulator surfaces rubbing together or pulling apart. Static charge is an unbalanced electrical charge at rest.
