Orion P-1403 vs P-3101 vs P-1610 vs P-0711: DNQ-THBP Grades Compared
Compare Orion P-1403, P-3101, P-1610 and P-0711 DNQ-THBP PAC grades — powder vs liquid, matched novolak, supply forms. Request product sheets.
Photoresist formulators sourcing DNQ-THBP photoactive compounds (PACs) face four Orion grades with different physical forms and resin integration paths. The wrong grade adds dissolution steps, resin-matching work, or coating-line requalification you did not plan for.
This comparison maps each Orion P-series grade to its confirmed form, novolak relationship, and the buyer profile it fits — using only verified product data. Where exact SKU distinctions are not confirmed in Orion's published specifications, those gaps are flagged explicitly rather than guessed.
DNQ-THBP in one paragraph
DNQ-THBP is the industry-standard PAC for positive-tone g-line (436 nm) and i-line (365 nm) microlithography. Novolak resin acts as the base matrix; THBP esterified with DNQ functions as the PAC. Standard blend ratio is 3.0–3.5 parts novolak to 1 part PAC.
Orion supplies the DNQ-THBP building block overview chemistry plus four application-ready grades: P-1403, P-1610, P-3101, and P-0711. Each addresses a different point in the formulator's workflow — from full resin control to turnkey liquid supply.
See the DNQ-THBP building block overview for wavelength context and grade-selection guidance.

Orion P-1403 — dry powder, your resin choice
Orion P-1403 is a yellow to yellow-brown DNQ-THBP building block supplied as dry powder. You blend with your choice of cresol novolak resin at 3.0–3.5 parts resin to one part P-1403.
This grade suits formulators who:
- Control novolak resin selection and acid-dissolution rate (ADR) for developer resistance
- Dissolve in ethyl cellosolve or Dowanol-PGMA before spin coating
- Run g-line or i-line positive photoresist programmes on silicon wafers
P-1403 offers maximum formulation flexibility. You carry the resin-matching work, but you also control contrast, dissolution rate, and developer compatibility.

Orion P-3101 — 20% solids ready liquid
Orion P-3101 is a 20% solids ready-to-use DNQ-THBP coating solution. Solvents and resin are pre-selected — spin-coat directly without in-house dissolution.
This grade suits coaters and fabs who:
- Want fast line qualification without managing resin selection or solvent blends
- Need a turnkey PAC/resin blend for spin-coating trials
- Run g-line or i-line positive photoresist programmes
The trade-off against P-1403 is flexibility: you accept Orion's pre-selected resin and solvent system in exchange for a shorter path from delivery to spin coater.

Orion P-1610 — dry powder with matched novolak
Orion P-1610 is a yellow to yellow-brown DNQ-THBP building block supplied as dry powder with a matched novolak resin included. Orion's product data describes it as optimised for i-line dominance with sharper contrast and higher resolution than P-1403 alone.
This grade suits formulators who:
- Want Orion-selected novolak paired with DNQ-THBP PAC at the standard 3.0–3.5 : 1 ratio
- Target i-line (365 nm) programmes where contrast and sidewall quality matter
- Prefer faster qualification than sourcing and matching their own novolak to P-1403

Orion P-0711 — DNQ-THBP-CNR PAC
Orion P-0711 is a DNQ-THBP cresol novolac resin (CNR) photoactive compound for positive-tone g-line, i-line, and advanced i-line imaging on silicon wafers. Published resolution target: 0.35–0.5 μm nodes.
Supply forms: dry powder, plus 30%, 15%, and 7% ready solutions in recommended solvents (PGMEA, ethyl lactate, ethyl cellosolve).
This grade suits programmes requiring:
- Optimised bleaching at 365 nm (i-line)
- Advanced i-line capability with controlled esterification
- Thermal flow resistance during high-temperature bake and hard-mask etch
- Multiple supply forms matched to different coating equipment

How to choose the right grade
Start with your integration point:
- Full formulation control → P-1403 (powder + your novolak)
- Fastest spin-coater qualification → P-3101 (20% ready liquid)
- Orion-matched novolak, i-line focus → P-1610 (powder with matched resin)
- CNR PAC with advanced i-line resolution → P-0711 (powder or ready solutions)
Then confirm with documentation: Request the product information PDF and method-of-use guidance for your shortlisted grade. Compare against your exposure wavelength, developer system, and spin-coater solids requirement before trial quantities.

Common questions.
What is the difference between Orion P-1403 and P-1610?
P-1403 is dry DNQ-THBP powder without resin — you select and blend your own cresol novolak at 3.0–3.5 : 1. P-1610 is dry DNQ-THBP powder with a matched novolak resin included, described as optimised for i-line dominance. Both are g-line/i-line capable; the difference is who selects the novolak matrix.
When should I choose P-3101 over P-1403?
Choose P-3101 when you want a 20% solids ready liquid with pre-selected solvents and resin — no in-house dissolution step. Choose P-1403 when you need full control over novolak resin selection and blend ratio for a custom formulation programme.
Does Orion P-0711 replace P-1610 for i-line work?
Not automatically. P-0711 is a DNQ-THBP-CNR PAC with published 0.35–0.5 μm resolution targets and four supply forms. P-1610 is a DNQ-THBP powder with matched novolak. The right grade depends on your process, resolution target, and whether you need a CNR PAC system or a standard THBP building block. Request both product information PDFs and run parallel trials.
What documentation does Orion provide for DNQ-THBP grades?
Product information PDFs and method-of-use guidance are available per grade. COA, MSDS, and TDS are supplied on request. Contact sales@orionppp.com to match a grade to your spin coater, exposure wavelength, and developer system.
