What it is
The EVG 150 is a modular cluster tool for coating and development of i-line photoresists.[1]
It is equipped with two loading and unloading ports, an optical wafer centering station, three spin-coating modules, one development module with puddle and spray options, three stacks of hotplates and coolplates, and an additional HMDS-priming module.[1]
How it works
The individual processing modules are fed by a dual end effector robot.[1]
Sequences consist of sub-recipes running in individual modules. Several sequences can be active in parallel, and the flow is managed in real time by software and optimized for maximum throughput or for prioritization of critical steps.[1]
Process stability is enhanced by an airborne molecular contamination filter on top of the tool and by active control of chamber and resist/developer line temperature.[1]
Where it fits in the process flow
The tool handles standard SEMI wafers of 100 mm and 150 mm diameter, including opaque wafers such as silicon and SOI and transparent wafers such as glass, fused-silica, and sapphire.[1]
Its process flow library includes coating sequences, development sequences, cleaning, and maintenance sequences. The coating options include surface preparation by HMDS, dehydrate, or none, and solvent clean by standard or edge bead removal.[1]
Applications
The EVG 150 is used for photoresist coating and development processes in i-line photolithography.[1]
Photoresists currently available on the tool include AZ ECI 3007, AZ ECI 3027, AZ 1512 HS, AZ nLOF 2020, AZ nLOF 2070, and MC PC62E. Bottom layers currently available include LOR 5A, LOR 15C, and XHRiC-16 II.[1]
The available developer chemistries are metal ion free TMAH-based AZ 726 MIF, metal ion containing KOH-based AZ 400K 1:3.5, and aluminum-friendly sodium metasilicate/phosphate-based AZ developer III.[1]
