ESD Association (ESDA) has issued an ESD Technology Roadmap on 4-March 2005.
This ESD Technology Roadmap provides ESD sensitivity trend for electronic devices for
Human Body Model (HBM), Machine Model (MM) and Field Induced Charge Device Model (CDM) for majority of CMOS devices (including RF).

The ESD Technology Roadmap shows ESD Sensitivity level trend only up to year 2010,
and it will only be valid for reference until end of next year.

Up to year 2010, the ESD Coordinator has to ensure his ESD personnel grounding processes are generating less 100 Volts HBM, machine parts that are in contact with ESD sensitive devices are grounded at all times, voltage induced on the ESD Sensitive parts is less than 50 Volts.

ESD Coordinator has to ensure he has all the necessary ESD equipments in order to perform ESD assessment on the ESD processes in the electronic manufacturing lines.

Some of the required ESD Equipments are:

• ESD Charge Plate Monitor with a graphical recording device or a ready made Human Body Voltage Measurement System
• ESD ground meter
• ESD Contact voltmeter

As years go by, the electronic device is required to perform faster, getting smaller and denser.
These features make the electronic devices become more vulnerable to ESD damage in years to come.

What would be the new control limit like for HBM, MM and CDM for year 2011 and beyond?
Would the control limits for all the three ESD damage models remain unchanged for year 2011?

The ESDA has a job to do.
The ESD Technology Roadmap is about to reach its final year next year.
It is time for it to be revised and republished.

• Radio Frequency components
• Disk Drive head (Magneto resistive heads (MR), Giant Magneto resistive heads (GMR))
• Complementary Metal Oxide Silicon (CMOS) Integrated Circuits (ICs)
• Gallium Arsenide Field Effect transistors (GaAsFETs)
• Reticles
• Random Access Memory (RAM) chips Among the all, GMR is the most sensitive parts with ESD withstand voltage in a few volt range.
  

The ESD sensitivity level for majority of modern ESD sensitive parts are documented in their component datasheets. The threshold voltage for Human Body Model (HBM), Machine Model (MM), Charge Device Model (CDM) for the ESD sensitive parts is in the datasheets. ESD sensitive parts are packaged in the ESD packaging that suits the parts. The ESD sensitive parts can be identified through an ESD symbol. The most commonly used ESD symbols are described here:

• A bar is across the human’s hand
• Three arrows pointing inwards (this is an obsolete Military symbol but it is still widely used by component manufacturers)

These symbols are either printed in paper sign-labels or permanently imprinted in the part’s packaging, for example the ESD symbol is placed on the reels.

A proper handling of ESD sensitive parts is required when handling the ESDS parts.
