Developer: TMAH Manual 02

Tool description
The Developer: TMAH manual 02 is a semi-automatic and programmable single substrate developer system, which can be used for development of resists on chips, 50 mm, 100 mm and 150 mm substrates. The development is done using AZ 726 MIF, which is a 2.38% TMAH solution with wetting agent.
Single substrates are loaded manually into the tool, but the developer dispense, puddle time, agitation, rinse and drying is controlled by the tool.
| Product: | Laurell EDC-650-HZB-23NP |

User manual
The user manual and contact information can be found in LabManager - requires login
Tool training
Training on the tool requires users to complete the lithography TPT followed by the online tool training and a hands-on authorization training.
The tool training video is part of the online tool training, but can also be viewed here.
| Tool purpose |
Development of UV resists:
Development of DUV resists:
|
|---|---|
| Developer | AZ 726 MIF (2.38% TMAH) |
| Development method | Puddle |
| Handling method |
|
| Process temperature | Room temperature |
| Process agitaion | 15 cycles per minute |
| Process rinse | DI water |
| Substrate sizes |
|
| Substrate materials |
|
| Substrate batch size | 1 |
Process information
All recipes use the following structure:
- Pressurize the TMAH canister
- Dispense puddle while rotating substrate slowly
- Puddle development with agitation of substrate
- Spin off developer
- Clean substrate and chamber with DI water
- Dry substrate and chamber with nitrogen
Multi puddle
Multi puddle recipes repeat steps 2-4 for the given number of puddles.
Process recipes
(Updated 2026-01-12, JEHEM)
- -Rinse-
- 1x015s
- 1x030s
- 1x060s
- 1x120s
- 2x060s
- 5x060s
Agitation
Testing showed that adding agitation to the puddle step gave better uniformity in the development rate over the entire area of the substrate as well as increased development rate.
Tests were performed on under-exposed resist, specifically for showing the difference between the agitation and non-agitation puddle development - the measured results cannot necessarily be transferred directly to a working process, only the vague general behavior of the two process setups; faster/slower development speed and better/worse uniformity across substrate.


| Non-agitation | Agitation | |
|---|---|---|
| Test results |
|
|
| Normalized development rate | 1 | 1.20 |
| Non-uniformity | 21% | 11% |
| Agitation | None | 15 cycles per minute, 20 rpm, 500 rpm/s |
| Substrate | 100 mm SSP silicon | |
| Resist film | 1.5 µm AZ 5214E | |
| Exposure dose | 50 mJ/cm2 (~50% of normal dose) | |
| Development | Single puddle for 60 seconds | |
