Aqueous substrate cleaning chemistries: MerckRecent Research Landscape
Substrate surface contamination leads to catastrophic device failure during fabrication. These formulations utilize specific chemical gradients to remove particulates without damaging sensitive underlying topographies.
What technical problems is Merck addressing in Aqueous substrate cleaning chemistries?
Insufficient lithographic resolution limits
(7)evidences
Poor structural integrity and resolution limits in thick film and overlayer applications. Improving pattern fidelity prevents structural collapse and dimensional inaccuracies during lithographic processing.
Fine pattern feature collapse
(6)evidences
High aspect ratio resist features frequently suffer from mechanical instability and capillary force damage during aqueous processing. Preventing pattern deformation or detachment ensures the dimensional integrity of semiconductor devices.
Resist pattern collapse
(6)evidences
High aspect ratio photoresist features frequently deform or break due to capillary forces during the cleaning and drying stages. Preventing this mechanical failure allows for smaller, denser semiconductor architectures.
Substrate surface contaminant persistence
(5)evidences
Incomplete removal of hardened photoresist and metallic byproducts leads to device defects. Eliminating these contaminants ensures electrical integrity and high manufacturing yields.
