Current Control Plans & FMEAs

A Technology/Family Control Plan / Device FMEA follows an entire flow for a ‘technology’ through a defined entity. This is in contrast with a ‘process’ flow where there is an individual Control Plan for each piece of equipment or a manufacturing ‘cell’ (company definition). A ‘Technology’ consists of many similar devices.

‘Receiving’ in FAB FMEAs consists of what the FAB looks at when materials arrive. Received materials, such as gasses, liquid chemicals and related materials must be addressed. Registrar interpretation Q5 1/12 (AEC-A100): “...So in effect, supplier's control plans will include wafers, gases, and chemicals...”

Device FMEA / Technology / Family Control Plan’ = a flow of a ‘technology’ or ‘device’

Process FMEA covers an ‘equipment set’ or ‘cost block’

This is a discussion of one methodology for control plans and FMEAs, etc. The intent is to provide coverage in a way which is minimally complex and simplifies the required documentation.

In this system, ‘like’ devices or ‘families’ have common documents reducing the total number of documents.
