Once upon a time, microchips were (relatively) simple and so was servicing the machines used to make them: if a machine stopped working, you called a technician. We call this break/fix model Service 1.0.As chips became more sophisticated, instead of just repairing the equipment, Service 2.0 aimed to make it faster and more efficient.Today, chips are almost unimaginably complex and we’re on the brink of Service 3.0, where virtually everything in the fab is monitored to identify subtle shifts that could affect chip performance.Recently, Dan Hutcheson, CEO of VLSIresearch, explored the evolving nature of service with Charlie Pappis, group vice president and general manager of Applied Global Services.
