WIRING SUBSTRATE AND SEMICONDUCTOR PACKAGE
20180019196 · 2018-01-18 ·

A wiring substrate includes an insulating layer and a wiring layer buried in the insulating layer at a first surface of the insulating layer. The wiring layer includes a first portion and a second portion. The first portion is narrower and thinner than the second portion. The first portion includes a first surface exposed at the first surface of the insulating layer. The second portion includes a first surface exposed at the first surface of the insulating layer and a second surface partly exposed in an opening formed in the insulating layer. The opening is open at a second surface of the insulating layer opposite to the first surface thereof.
