Abstract
A manufacturing method of a carrier for a semiconductor chip mounting thereon is provided. The method includes at least the following steps. A plurality of conductive connectors is formed on a fine redistribution structure to form a first portion, where the semiconductor chip is adapted to be mounted on the fine redistribution structure opposite to the conductive connectors. Each of the conductive connectors includes a bump and a solder cap formed on the bump, and the bump is directly connected to the fine redistribution structure. The first portion is disposed on a second portion, where the second portion includes a top redistribution structure directly connected to the solder cap and a second redistribution structure connected to the top redistribution structure, the first portion is disposed on the top redistribution structure, and a contact density of the top redistribution structure is denser than a contact density of the bottom redistribution structure.
