Sulfonate electrolyte leveling agents: BASFRecent Research Landscape

Dendrite formation and bath oxidation lead to poor metal morphology and frequent electrolyte replacement. These innovations stabilize the chemical bath to ensure uniform deposition and extended process life.

What technical problems is BASF addressing in Sulfonate electrolyte leveling agents?

Tin whisker formation

(7)evidences

Irregular surface morphology and spontaneous oxidation of tin ions lead to poor coating quality. Preventing these degradation modes ensures structural integrity and bath longevity.

Nonuniform metal deposition thickness

(6)evidences

Irregular deposition rates across micro-features lead to surface roughness and structural defects. Achieving planarization prevents electrical failure and mechanical instability in high-density interconnects.

Submicron feature filling voids

(5)evidences

Non-uniform deposition and void formation during metal plating lead to structural failures. Eliminating these defects ensures high-reliability interconnects in semiconductor manufacturing.

Uncontrolled metal crystal growth

(3)evidences

Irregular growth and dendritic formations during electrolytic deposition lead to poor surface quality and structural defects. Controlling morphology ensures uniform metal thickness and prevents short circuits in refining processes.
