Trim/Cut Methodology
L-Cuts: 2nd leg (fine cut segment) perpendicular to 1st leg (coarse cut segment)
Curved L-Cuts: L-cut with radial corner, minimizes micro-cracking at corner
Plungecuts: Straight cut parallel to resistor width, perpendicular to direction of current flow
Scancuts: Raster motion, wide cuts, typical on high-power or geometrically-sensitive RF circuits
Serpentine Cuts: Plunge cuts, alternate sides, high dynamic range
U-Cuts: Inverted āUā starts / stops outside resistor, minimum accuracy but maximum stability
Non-Orthogonal Plungecuts: Cuts @ angles other than standard X / Y, typical on wiper circuits
Ladder Cuts: Step-function link trim, typical on passive resistor networks
Predict / Incremental: Cut-Measure repeat cycle, typical on active trim / tight-tolerance
High Resolution: Predict / Incremental trim @ 0.14um incrementation
Radial: Radial resistor trimming / pattern etch
