PERTOP tube PECVD solution
Yingkou Jinchen Machinery Co., Ltd. ↗PERTOP is Jinchen's tube PECVD solution for growing silicon oxide and in-situ doped amorphous silicon. Jinchen presents it as a process technology with dust and uniformity controls; tube layout and throughput are set in a proposal for your line.
Process solution sold per project. Model, tube configuration, capacity and utility needs come with Jinchen's proposal.

START WITH YOUR PRODUCTION TASK
Start from your film stack and wafer input, agree how a good layer will be measured, and only then compare batch capacity between offers. Ask Jinchen to confirm in writing the model, tube layout, cycle definition and film acceptance limits for your order.

01 · Manufacturer information
What PERTOP does
Oxide plus doped silicon
PERTOP grows silicon oxide and then in-situ doped amorphous silicon in one combined route. Send Jinchen your required stack so the offer lists exactly which operations the tool performs. In cell production this stack forms the passivating contact of TOPCon cells, made after diffusion and before metallization.
Uniform, clean films
Jinchen highlights uniformity, dust control and film stability during crystallization. Set your own wafer sampling plan, measurement points and defect criteria so these features become acceptance limits.

From process need to quotation
| Topic | What you send Jinchen | What to request back |
|---|---|---|
| Wafers and batch | Format, thickness, surface condition and batch loading. | The proposed carrier and tube set-up, run on representative trial wafers. |
| Film stack | Required layers and how each one is measured. | Recipe scope and film results at agreed wafer and batch positions. |
| Particles and defects | Defect types that matter to you and how you inspect for them. | Trial records that state the sampling and any excluded wafers. |
| Downstream handover | The next process step and its transfer needs. | Who is responsible for the output condition and wafer handling. |

Comparing PERTOP with other PECVD offers
PECVD names a deposition method. Two offers under that name can differ in tube layout, recipes, loading, process controls and the way acceptance is measured, so line them up on those points. Output per shift depends on your installation and recipe, and should be calculated for them.
Ask Jinchen how cleaning, recipe changes and interrupted batches are counted in its capacity figure. Gas supply, exhaust and site services need a utility schedule for the delivered tool and a check by a qualified integrator before installation. Gas-handling limits come from Jinchen's operating documents for the tool.

Checklist for a PERTOP quotation
Film and wafers
Send the layer targets, wafer input and the measurements your process team uses.
Tool scope
Request the tube or chamber layout, carriers, loading method and the process controls included.
Acceptance
Agree film uniformity, contamination sampling and downstream checks on representative wafers, and ask Jinchen to confirm them in writing.
Site and output
Request utility and exhaust documents and an output figure that already allows for interruptions and cleaning.
