Abstract

Embodiments relate to the design of an electronic device capable of preventing a lateral motion between a first body and a second body. The device comprises a first body comprising one or more atomic force microscopy (AFM) tips protruding from a first surface of the first body. The device further comprises a second body comprising one or more electrical contacts on a second surface of the second body. The second surface faces the first surface. The one or more electrical contacts pierced by the AFM tips of the first surface to prevent a lateral motion between the first body and the second body.

Claims (25)

1. A method comprising:

positioning a first body relative to a second body to align one or more atomic force microscopy (AFM) tips protruding from a first surface of the first body with one or more electrical contacts on a second surface of the second body facing the first surface;

approaching the first body and the second body after positioning the first body;

piercing the one or more electrical contacts with a corresponding AFM tip of the one or more AFM tips to prevent a lateral movement between the first body and the second body, after approaching the first body and the second body; and

collapsing the one or more AFM tips in the one or more electrical contacts, after piercing the one or more electrical contacts.

2. The method of claim 1 , wherein electrical interconnects are formed by the one or more AFM tips and the one or more electrical contacts.

3. The method of claim 1 , wherein the one or more AFM tips comprise a top metal layer.

4. The method of claim 1 , wherein one of the first body and the second body comprises a light emitting diode (LED) having a size that is less than 100 micrometers (μm) and the other of the first body and the second body comprises a circuit to operate the LED.

5. The method of claim 1 , wherein the one or more electrical contacts comprise a porous conductive material.

6. The method of claim 1 , wherein the one or more AFM tips are positioned on the first surface in a grid pattern.

7. The method of claim 1 , wherein one of the one or more AFM tips is positioned on each corner of the first surface.

8. An electronic device comprising:

a first body comprising one or more atomic force microscopy (AFM) tips protruding from a first surface of the first body; and

a second body comprising one or more electrical contacts on a second surface of the second body facing the first surface, the one or more electrical contacts pierced by the one or more AFM tips of the first surface to prevent a lateral motion between the first body and the second body during approaching of the first body and the second body, and wherein the one or more AFM tips are collapsed in the one or more electrical contacts.

9. The electronic device of claim 8 , wherein the collapsed one or more AFM tips and the one or more electrical contacts form electrical interconnects.

10. The electronic device of claim 8 , wherein one of the first body and the second body comprises a light emitting diode (LED) with a size that is less than 100 micrometers (μm) and the other of the first body and the second body comprises a circuit to operate the LED.

11. The electronic device of claim 8 , wherein the one or more electrical contacts comprise a porous conductive material.

12. The electronic device of claim 8 , wherein the one or more AFM tips are positioned on the first surface in a grid pattern.

13. The electronic device of claim 8 , wherein one of the one or more AFM tips is positioned on each corner of the first surface.

14. An electronic device manufactured by a method comprising:

positioning a first body relative to a second body to align one or more atomic force microscopy (AFM) tips protruding from a first surface of the first body with one or more electrical contacts on a second surface of the second body facing the first surface;

approaching the first body and the second body after positioning the first body;

piercing the one or more electrical contacts with a corresponding AFM tip of the one or more AFM tips to prevent a lateral movement between the first body and the second body, after approaching the first body and the second body; and

collapsing the one or more AFM tips in the one or more electrical contacts, after piercing the one or more electrical contacts.

15. The electronic device of claim 14 , wherein electrical interconnects are formed by the one or more AFM tips and the one or more electrical contacts.
