| 主权项 | 1. A circuit board comprising: a base substrate; an interlayer insulating layer covering the base substrate; a via structure passing through at least the interlayer insulating layer of the base substrate and the interlayer insulating layer in the vertical direction; and an etch stop pattern disposed on the interlayer insulating layer in the horizontal direction perpendicular to the vertical direction to surround the via structure and made of an insulating material, the interlayer insulating layer comprising a first insulating layer covering the base substrate to surround a lower portion of the via structure, anda second insulating layer covering the first insulating layer to surround an upper portion of the via structure, andthe first insulating layer and the second insulating layer are made of different photosensitive insulating materials. | ||
