SEMI T19 - Specification for Device Marking -

Abstract

The purpose of this Standard is to establish a standard specification of marking on semiconductor devices to identify individual device by unique identification code and possible optional information to suggest a part of manufacturing information.

This Specification ranges from bare semiconductor dice to be packaged or assembled devices.

While this Standard specifies physical interface of marking depending on one or more available technologies, it doesn’t restrict specific means of writing, reading alignment and so on.

This Standard also handles a part of logical interface about the information of the marking.

This Standard does not specify specific means to mark (writing) nor to identify (reading) the mark but guide possible ones implicitly with geometric requirements.
