EmerALD® XP ALD
EmerALD XP is a process module designed to deposit thin conformal metal and dielectric layers by atomic layer deposition (ALD) used for advanced CMOS gate stacks and other applications.
Major features
The EmerALD reactor chamber uses a showerhead-process gas distribution method to assure uniform gas delivery to the wafer surface. EmerALD also has a remote plasma chamber clean capability which for many processes allows the option of maintaining chamber performance for longer periods between chamber cleans resulting in higher uptime.
Up to four EmerALD process modules can be configured to the XP cluster platform, which is a member of ASM’s XP common platform series.
Emerald XP ALD benefits
- Showerhead design for uniform reactant concentration providing excellent film performance on varied topographies;
- Small showerhead and wafer chamber volume, optimized for ALD to increase throughput;
- Direct and remote plasma to provide extended process control capabilities;
- In-situ chamber clean for higher uptime.
