PHOTONEECE photodefinable polyimide

Toray Industries · Material properties and interface engineering

Purpose: Compare photodefinable dielectric options for RDL insulation and die-surface protection within the PHOTONEECE polyimide family.
Technical approach: Coating, exposure, development and curing form patterned PI. Positive- and negative-tone choices require grade-specific process selection.
Scope of use: For wafer/panel RDL, buffer coatings and interlayer insulation. Low-temperature, thick-film and formulation properties vary by series.
Limitations and open questions: These evaluation considerations are compiled by BLNKK from public information. They are not supplier guarantees or a mandatory submission checklist.
Scope and limitations
The family name does not establish universally low cure temperature, low warpage or NMP-free chemistry. A patterned via does not establish clean contacts or acceptable resistance.
What to prepare
BLNKK suggests preparing features, thickness, metal surfaces, lithography equipment and cure budget, with adhesion, shrinkage, moisture and contact-resistance checks.
Confirm with the supplier
Confirm the exact grade, tone, solvent/developer and cure process. Request current TDS and relevant post-cure property, adhesion and reliability data.
Public evidence: The primary tables and semiconductor portfolio identify applications and distinct standard/K series. Individual grade data remain necessary.
