Boxes |
Boxes open a window in material which may be used to measure etch depth, for example by stylus profilometry or spectrophotometry. |

Vernier enables accurate measurement of layer to layer registration. Should be places at least two locations on the wafer (preferably far apart) if wish to measure rotation as well as shift in x and y. |
2.4. Critical dimension measurement
[CIF (5K)] [GDSII (8K)] | ||
---|---|---|
GDSII Layer | CIF Layer | Description |

CAL |
Crosses |
Set of critical dimension crosses. Necessary to have cross with width of minimum feature size for mask maker to measure if the critical dimension is not embodied as a line anywhere in the layout. Crosses of smaller dimensions than the critical dimension should be deleted (although they will probably be dropped from the data when made in to masks anyway). |
2.5. Design rule measurement set

Steps |
Should be used in conjunction with vernier (as measurements need to be corrected for misalignment). Should be able to determine for which line width and distance over step that the line properties are adequate, to determine design rules for the two interacting layers. |
