Redistribution layer for substrate contacts
First Claim
1. A structure with an interconnection layer for redistribution of electrical connections, comprising:
- a substrate having a side;
a plurality of first electrical connections disposed on the side of the substrate in a first arrangement, each of the first electrical connections having a first size;
a single insulating layer comprising a cured material coated on the side of the substrate over the first electrical connections;
a plurality of second electrical connections disposed on the insulating layer in a second arrangement and disposed on a side of the insulating layer opposite the plurality of first electrical connections, each of the second electrical connections having a second size, wherein the second sizes are greater than the first sizes, each second electrical connection of the plurality of second electrical connections electrically connected to a respective first electrical connection through a via having a size corresponding to the first size of the respective first electrical connection and smaller than the second sizes of the plurality of second electrical connections;
a plurality of integrated circuits disposed on the side of the substrate, each electrically connected to a set of the first electrical connections that are more closely spaced within the set on the substrate side than within a corresponding set of the second electrical connections on the insulating layer.

Abstract
A structure with an interconnection layer for redistribution of electrical connections includes a plurality of first electrical connections disposed on a substrate in a first arrangement. An insulating layer is disposed on the substrate over the first electrical connections. A plurality of second electrical connections is disposed on the insulating layer on a side of the insulating layer opposite the plurality of first electrical connections in a second arrangement. Each second electrical connection is electrically connected to a respective first electrical connection. An integrated circuit is disposed on the substrate and is electrically connected to the first electrical connections. The first electrical connections in the first arrangement have a greater spatial density than the second electrical connections in the second arrangement.
