P01 PROCESS OVERVIEW

Understand the process
before changing
the solution.

We start from your actual result, identify what controls the process, and translate the findings into the right chemistry, process conditions and equipment configuration.

Discuss Your Process

P02 FROM RESULT TO EVIDENCE

Start from what you see.
Find what really matters.

We analyze the observed result, consider possible variables, and verify their impact through controlled comparison to find the causes and improvement direction.

  1. 01

    Observed result

    Actual surface / profile / defect after process

    Conceptual expected product surface and observed surface issue

    Expected result / Observed issue

  2. 02

    Possible variables

    Multiple factors can affect the process result

    • Temperature
    • Time
    • Flow / Contact
    • Chemistry
    • Transport Speed
    • Equipment Function
  3. 03

    Controlled comparison

    Change one factor at a time under controlled conditions

    Condition A · Condition B · Condition C

  4. 04

    Evidence

    Understand the response and key factors

    Conceptual evaluation evidence

P03 PROCESS WINDOW

Find the stable process window.

We evaluate the relationship between key process conditions and product response to define a stable and robust process window for your target result.

  1. 01

    Key variable analysis

    Evaluate the effect of each condition on process response

    • Temperature
    • Time
    • Flow / Contact
    • Chemistry
    • Transport Speed

  3. 03

    Process window

    Define the acceptable range for stable and consistent result

    Illustrative process window; no actual process data

    Temperature × Concentration

  4. 04

    Typical evaluation items

    Key results used to judge process performance

    • Surface appearance / defect
    • Etch / strip rate (relative)
    • Uniformity (within / across)
    • Residue / by-product
    • Material selectivity
    • Process stability (repeatability)

All analytical visuals are conceptual; they do not represent actual measurements, customer data or real process conditions.

P04 FROM EVIDENCE TO PRODUCTION

Translate findings into
practical process solutions.

The identified process window is translated into chemical development or optimization, process requirements and equipment functions for production and validation.
