LDP Method Explained
- LDP method uses electric discharge to create plasma for EUV light with high temperatures up to 200,000 Celsius.
- It provides efficiency and stability advantages over LPP by continuously replenishing tin on rotating disks.
Scaling Limits of DPP
- DPP methods face challenges scaling to thousands of pulses per second needed for economic viability.
- Thermal damage and tin vapor condensation impose significant engineering hurdles.
LDP Efficiency Advantages
- LDP's rotating tin supply wheels improve efficiency by guaranteeing laser hits and mitigate heat and debris.
- This design addresses key issues faced by LPP's droplet targeting method.
