MOSIS Die ID Implementation

Allowing MOSIS to create an internal die ID

MOSIS is now supporting an internal die identification option on all MOSIS GlobalFoundries(GF) MPW runs. Internal labeling will result in a net reduction of 30 µm in the Y dimension. This is accomplished by eliminating the 30 µm overhead MOSIS currently adds to the top of customer layout as submitted for die labeling on MPW runs.

To qualify for internal labeling, a project must have a standard LOGOBND region in the upper right hand corner of the layout (as produced by the standard GF p-cell), it must not have any layout on the top metal level. In all cases (chamfered or square) the minimum LOGOBND box needs to be 84 µm x 71 µm. MOSIS will then place the fabrication id in this LOGOBND region.

Examples

Internal Labeling: when design contains LOGOBND and no layout in the upper right hand corner on the top metal level, and technology has chamfered corners.
