Non-conductive film and non-conductive paste including zinc particles, semiconductor package including the same, and method of manufacturing the semiconductor package
First Claim
1. A semiconductor package comprising:
- a first substrate including first electrode terminals;
a second substrate including second electrode terminals facing the first electrode terminals; and
a non-conductive material layer containing a dispersion of pure zinc (Zn) particles having an average particle diameter of about 1 nm to about 200 nm unevenly distributed in the non-conductive material layer such that a concentration of the zinc (Zn) particles in the non-conductive material layer at a location that is separated by a first distance from each of the first electrode terminals is less than a concentration of the zinc (Zn) particles at a location that is separated by a second distance, that is greater than the first distance, from each of the first electrode terminals, and also where the non-conductive material layer is disposed between the first substrate and the second substrate.

Abstract
A non-conductive material layer, selected from a non-conductive film and a non-conductive polymer paste, and containing a dispersion of zinc (Zn) particles is disclosed, together with semiconductor packages including the non-conductive material layer. The non-conductive material layer contains zinc (Zn) particles having an average particle diameter of about 1 nm to about 200 nm in a non-conductive polymer base material of a film type, and a semiconductor package includes the non-conductive film. By using the non-conductive film and/or the non-conductive paste containing the zinc dispersion, e a semiconductor package having excellent electric connection properties and high reliability may be manufactured through simple processes at low manufacturing costs.
