ABSTRACT:
Disclosed herein is a printed circuit board with an embedded thin-film capacitor, and a method of manufacturing the same.Specifically, the present invention relates to a printed circuit board with an embedded thin-film capacitor, comprising a lower electrode formed on an insulating substrate; an amorphous paraelectric film formed on the lower electrode; a metal seed layer formed on the paraelectric film; and an upper electrode formed on the metal seed layer and having a surface roughness (Ra) of more than 300 nm; anda method of manufacturing a printed circuit board with an embedded thin-film capacitor, comprising forming a lower electrode on an insulating substrate; forming an amorphous paraelectric film on the lower electrode, using a low-temperature film formation process; forming a metal seed layer on the paraelectric film; and forming an upper electrode having a surface roughness (Ra) of more than 300 nm on the metal seed layer, using an electroplating method.
