The A-line field Definition of the measures used in the table below The A-line fields have trenches of different widths across the entire 1 cm height of the field. The pitch of the trenches is matched to the exposed area of each mask. The list of trench widths in each field is the same on all masks (due to the high exposed area the widths 2 and 3 µm are missing on the travka 65 mask, on the 80 mask the lines 2, 3, 4 and 6 are missing).
The A-line fields are located along a cleavage line on the wafer with T-ridge fields. Cleaving across these two types of fields provide the possibility of inspecting trench depths and widths as a function of exposed area.
