TSMC18

TSMC Layer Map

This is the layer map for the TSMC 0.18 micron 6 metal, 1 poly (silicided) layout rules (TSMC18), and only for those TSMC vendor design rules. For designs that are laid out using other design rules (or technology codes), use the standard layer mapping conventions of that design rule set.

Note #1:

MOSIS recognizes and process these optional metal fill and slot layers, beginning with runs closing in July, 2003.

Note #2:

This layer, which forms a MiM capacitor with METAL5 as the bottom layer, is the standard MiM for MOSIS MPW runs. Other CTM layers, which use different bottom plates, are also available, but only by special order. The GDS datatype indicates the bottom metal layer that is intended.

Note #3:

If this layer is present anywhere in the submitted design or anywhere in the design after instantiation, then MOSIS will not derive it. If this layer is not in the submitted design or anywhere in the design after instantiation, then MOSIS will derive that layer from the listed layers. MOSIS does not create a layer partially from a layer drawn by the customer and partially derived from other layers.
