From Microvia Formation to Copper Filling: A Process Overview

Reliable conductive microvias require more than a successful drilling step. Sidewall condition, seed-layer continuity, chemistry control, current distribution, and inspection strategy all influence fill quality.

Process integration should be evaluated as one connected system so that yield, planarity, adhesion, and electrical performance remain aligned.
