- Temperature uniformity：G-to-G，L-to-L，and Ch-to-Ch
- Rapid cooling ：Controling shrinkage issue
- Controling warpage issue
De-Hydrogenation
- Excellent temp. uniformity and substrate stability
- Capability of handling larger size substrate up to 2~8 Gen
- No warpage issue even with thin substrate
Product descriptions
There are increasing demands for high quality Displays with better resolutions.
High resolution display guarantees clean and vivid images but less allows patterning deviation with more pixels.
Thus, when manufacturing high resolution LTPS TFT, adding Pre-compaction process in the first place can prohibit shrinkage of TFT and reduce patterning deviation.
Features
- applied to high temp. process : > 700℃
- Excellent Temp. uniformity by chambers
- No warpage issue even with thin substrate
- Capability of handling larger size substrate up to 2~8 Gen.
Applicable process
- LTPS LCD, LTPS AMOLED
Product descriptions
A thin a-si silicon layer deposited by PECVD contains 10~15% of hydrogen.
De-hydrogenation process is to detach hydrogens from substrate, thus prevents damages from explosion of hydrogens.
Features
- Excellent temp. uniformity and substrate stability
- No warpage issue even with thin substrate
- Capability of handling larger size substrate up to 2~8 Gen.)
Applicable process
- LTPS LCD, LTPS Poly-si crystallization
- High temp. and rapid thermal process for LTPS TFT
Product descriptions
Crystallization converts a-si with low mobility into Poly-si with high mobility optimized for quality displays with quick response time.
Features
- Excellent temp. uniformity and substrate stability
- Capability of handling larger size substrate up to 2~8 Gen.)
- Upgraded thermal efficiency and high temp process capability by 750℃
Applicable process
- LTPS LCD, LTPS Poly-si crystallization
- High temp. and rapid thermal process for LTPS TFT
Product descriptions
Dopant activation is to arrange dopant in a regular pattern without leakage current and recover substrate from its damage by heavy dopant distribution for channel forming in Ion Implantation process.
Features
- Rapid substrate cooling without shrinkage issue
- Capability of handling larger size substrate up to 2~8 Gen.)
- No warpage issue even with thin substrate
