Catalog solutions · 4
TOK TLDP-300 laser-process protective coating
Include protective coating and removal as variables when comparing laser-processing surface contamination and damage.
TOK ST-120 thick-resist stripping solution
Check whether suspected resist residues are accessible and relevant to stripping before linking removal to contact resistance.
TOK PMER P-CY1000 deep-silicon-etch resist
Assess an upstream deep-Si etch mask in a TSV liner-leakage investigation, separating sidewall/residue checks from later dielectric coverage.
