Photomask & reticle
The master 'stencil' that a chip's circuit pattern is printed from - every wafer is exposed through it, so one flawed mask ruins everything printed after it.
Ranks moderate (50/100) - set apart by fragility to shocks (78) and structural importance (70).
Why it matters
No qualified mask, no wafer: masks are a universal, continuously-consumed front-end input with almost no supplier redundancy.
Why now
High-NA EUV brings smaller field sizes, new pellicle and blank requirements and half-field reticles just as leading-edge and HBM4 demand peaks, tightening an already concentrated mask supply.
If Photomask & reticle runs short
A mask-blank or pellicle plant outage, or a mask-inspection-tool bottleneck, throttles new tape-outs and leading-edge wafer starts within weeks.
In depth · editorial + model
Each leading-edge layer needs a defect-free EUV reticle built on an ultra-flat mask blank and protected by a pellicle. Blanks come from essentially two makers (Hoya, AGC), and actinic mask inspection is a Lasertec near-monopoly.
