## Abstract

A conductive pressure sensitive adhesive tape is provided. The conductive pressure sensitive adhesive tape includes a first metal foil, a polymer film attached to a surface of the first metal foil with a polymer binder interposed therebetween, a second metal foil attached to a surface of the polymer film with a polymer binder interposed therebetween, and a polymer adhesive layer formed on a backside of at least one of the first and second metal foils.

## Claims

### Claim 1

A conductive pressure sensitive adhesive tape comprising:
a first metal foil;
a polymer film attached to a surface of the first metal foil with a polymer binder interposed therebetween;
a second metal foil attached to a surface of the polymer film with a polymer binder interposed therebetween; and
a polymer adhesive layer formed on a backside of the second metal foil,
wherein at least one of the first and second metal foils is a rolled metal foil,
wherein throughholes are formed from the first metal foil and through the polymer film and the second metal foil in a vertical direction of the conductive pressure sensitive adhesive tape, and a conductive adhesive is filled into the throughholes so that the first and second metal foils connect with each other via the throughholes.

### Claim 2 (depends on 1)

The conductive pressure sensitive adhesive tape of claim 1, wherein the polymer adhesive layer is electrically conductive.

### Claim 3 (depends on 2)

The conductive pressure sensitive adhesive tape of claim 2, wherein the throughholes are formed before forming the electrically conductive polymer adhesive layer on the backside of the conductive pressure sensitive adhesive tape.

### Claim 4 (depends on 1)

The conductive pressure sensitive adhesive tape of claim 1, wherein an anti-oxidation is performed over the metal foil where the polymer adhesive layer is not formed.

### Claim 5 (depends on 1)

The conductive pressure sensitive adhesive tape of claim 1, wherein a conductive silicon rubber is uniformly coated on the metal foil with a predetermined thickness where the polymer adhesive layer is not formed.

### Claim 6 (depends on 1)

The conductive pressure sensitive adhesive tape of claim 1, further comprising a graphite sheet attached between said polymer film and said at least one of the first and second metal foils.

### Claim 7 (depends on 6)

The conductive pressure sensitive adhesive tape of claim 6, further comprising another polymer film attached between said graphite sheet and said at least one of the first and second metal foils.

### Claim 8 (depends on 1)

The conductive pressure sensitive adhesive tape of claim 1, wherein the first and second metal foils are formed with different metal.

### Claim 9 (depends on 8)

The conductive pressure sensitive adhesive tape of claim 8, wherein one of the first and second metal foils is formed with aluminum, and the other is formed with copper.

### Claim 10 (depends on 8)

The conductive pressure sensitive adhesive tape of claim 8, wherein one of the first and second metal foils is formed with aluminum or copper, and the other is formed with nickel.
