Copper plating - Wikipedia

Suppressor wets the photoresist and the leveler enters the via during the 7- to 8-minute plating process, to help create a pillar with a flat top. Both leveler and suppressor are polarizing agents that help control the plating uniformity across different die and wafer. The accelerator acts as a Cu grain-refiner, making a smooth and bright deposit.
