Yes
Only 1 SSB800 iLine scanner has been shipped to SMEE “customer” last September. It’s still not in production as of today. Like I said, many critical features are missing so the fab’s target application will be for the least critical layers with very loose specification/tolerance. Initial target applications would be for the polyamide or for the implant layers for memory fabs to test out SMEE SSB800 machines. SMEE is having trouble shipping the 2nd SSB800 iLine scanner
SMEE is also having trouble with shipping the first SSC800 KrF scanner.
First, resolution capability or half-pitch capability, does not have one-to-one correlation with the design/process node.
Assuming SMEE is really working on a 193nm dry SSA800, it’s more likely it will target 65nm resolution capability. Application for such tool would be for critical layers down to 55nm node.
The 193nm immersion resolution capability would be 38nm. with everyone indicating this scanner is to be equivalent to ArFi used for 28nm, the target specifications would mimic ASML’s NXT1950.
Thanks for your reply and corrections.
So I rewrite the summary.
Nobody knows for sure what's going on with SMEE, so this is the most pessimistic case, or let's say the case for which @hvpc has reliable and confirmed info.
1. SMEE new platform is a double wafer stage type and is named 800 series. This series totally replaces the obsolete 600 series.
2. SSB800 i-line capable of 280nm resolution. Shipped to 1 customer in September 2022. Still not in full production (although 4 months for installation and ramp up are not a lot). There is also a second machine of this type, but is still not delivered.
3. SSC800 KrF capable of 110nm resolution. Should be more or less ready but has still not been shipped to customer.
4. SSA800 dry Arf capable of 65nm resolution, for critical layers down to 55nm node. Not clear if this machine has been shipped already. Rumors say IRCD is testing a fully localized line for 55nm node. If rumor is confirmed, this probably is the machine used.
5. Prototype immersion Arf capable of 38nm resolution, for critical layers down to 28nm node. This machine is still in assembly / validation at SMEE and eventually will be delivered to customer for verification and testing within this year (according to havoc).
