HPAT260A
Atomic Layer Deposition
Application Field:
The independently developed and designed high-capacity tubular ALD coating machine provides ultra-thin and high-quality dielectric films such as SnOx, AlOx, NiOx, and ZnOx for the manufacturing of high-efficiency solar cells. It cooperates with automation to achieve stable and reliable operation.
Product Features
- The optimized spray plate and the chamber space improves the uniformity of the flow field, achieves ultra-large production capacity, and enhances maintainability
- The spare parts are easy to change and maintain
- Both the inner and outer chambers are equipped with sealing rings to prevent situations where the inner chambers cannot be tightly sealed
- Pull-out partitioned heating plate design for easy maintenance
- Optimized design of flow field space to reduce TMA loss and process time
