Charged
Device Model (CDM) ESD – From a Component / Packaging / Manufacturing
Perspective
Abstract: The Charged Device Model for ESD (CDM) is
the "real world" model which describes ESD-related damage to IC components from
automated manufacturing / handling. After an initial description of CDM
(contrasting to other ESD models), the effects on discharge peak current /
energy in terms of package characteristics will be discussed. Following
this will be examples of manufacturing process steps known to cause CDM charging
/ discharging issues (both for components by themselves and assembled on
systems). Finally, the current industry perspective on CDM will be
reviewed with key issues in technology / standards.
Biography: Alan
Righter currently is a External Foundry ESD Advisor for Analog Devices in
Wilmington, MA, having worked there since 1997. Previous to that, he
worked at Sandia National Laboratories in Albuquerque, NM from 1984-1997 in
different aspects of microelectronics (design, test, product engineering /
reliability, and failure analysis). He holds BSEE / MSEE degrees from
Arizona State University and a PhD from the University of New Mexico. Alan
currently chairs the ESD Association CDM working group committee WG5.3.1,
responsible for the Charged Device Model standard document ANSI/ESDA STM5.3.1
from the ESD Association. He is also on the Industry Council for ESD
Target Levels, a council of ESD experts tasked to review and recommend safe,
reliable ESD levels for the electronics industry reflecting current ESD controls
and IC design/manufacturing technology.
