350 nm lithography process
Semiconductor lithography processes technology
The 350 nanometer lithography process (350 nm or 0.35 µm) is a full node semiconductor manufacturing process following the 500 nm process node. Commercial integrated circuit manufacturing using 350 nm process began in late 1995. 350 nm was phased out and replaced by 250 nm in 1999.
