Microelectronic Security Coatings

US Patent:

8211538, Jul 3, 2012

Filed:

Jun 15, 2010

Appl. No.:

12/815775

Inventors:

Kenneth H. Heffner - Largo FL, US

Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

B32B 3/24, B41M 3/14, B44F 1/12

US Classification:

4283066, 428901, 428916, 427 7, 324500

Abstract:

A security coating on an electronic circuit assembly comprises a mesh coating that may have a unique signature pattern and comprise materials that easily produce an image of the signature so that it is possible to determine if reverse engineering has been attempted. Spaces in the mesh may include electrical components to erase circuit codes to destroy the functionality and value of the protected die if the mesh coated is disturbed. The voids may include compositions to enhance the mesh signature and abrade the circuit if tampering takes place.

Diffuse Reflectance Method And Apparatus For Determining Thickness Of An Infrared Translucent Layer

US Patent:

6459488, Oct 1, 2002

Filed:

Feb 10, 2000

Appl. No.:

09/502059

Inventors:

Kenneth H. Heffner - Largo FL

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

G01B 902

US Classification:

356504

Abstract:

A method for producing an interferogram of an infrared translucent layer that is on a reflective substrate, comprising generating parallel infrared interferometer beams by means of an infrared interferometer, converging the parallel infrared interferometer beams into converging infrared interferometer beams, sending the converging infrared interferometer beams onto the infrared translucent layer to produce diffusely reflected infrared interferometer rays from above and below the infrared translucent layer, and making the diffusely reflected infrared interferometer rays into parallel reflected infrared interferometer rays.

Data Protection When A Monitor Device Fails Or Is Attacked

US Patent:

2012019, Aug 2, 2012

Filed:

Jan 31, 2011

Appl. No.:

13/017633

Inventors:

William J. Dalzell - Parrish FL, US
James L. Tucker - Clearwater FL, US
Kenneth Henry Heffner - Largo FL, US

Assignee:

HONEYWELL INTERNATIONAL INC. - Morristown NJ

International Classification:

G06F 12/14

US Classification:

713190, 711163, 711E12092

Abstract:

In some examples, a system includes a data storage device that stores data and a monitor device that monitors a physical domain in which the data storage device is located and conditions access to data stored by the data storage device based on communication between the monitor device and the data storage device. In some examples, the system is configured to impede access to the data when at least one of operation the monitor device fails or the monitor device is attacked. Additionally, in some examples, the monitor device is configured to restrict access to the data when the monitor device is engaged and an attacker attempts to access the data storage device directly.

Integrated Circuit Stack

US Patent:

2013023, Sep 12, 2013

Filed:

Mar 9, 2012

Appl. No.:

13/416404

Inventors:

James L. Tucker - Clearwater FL, US
Gary Roosevelt - Clearwater FL, US
Kenneth H. Heffner - Largo FL, US
James Hobbs - Plymouth MN, US

Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

H05K 1/18, H05K 3/36, H05K 1/11

US Classification:

361783, 174262, 29830

Abstract:

In some examples, an integrated circuit system includes a plurality of integrated circuit layers. At least one of the integrated circuit layers includes an integrated circuit die, which may not include any through-silicon vias that provide a pathway to an adjacent integrated circuit layer, and an interposer portion, which includes electrically conductive through-vias. The interposer portion may facilitate communication of the integrated circuit die with other integrated circuit layers of the integrated circuit system. In some examples, the stacked integrated circuit system may include more than one integrated circuit die, which may be in the same integrated circuit layer as at least one other integrated circuit die, or may be in a different integrated circuit layer.

Coating Integrated Circuits Using Thermal Spray

US Patent:

6110537, Aug 29, 2000

Filed:

Apr 18, 1998

Appl. No.:

9/061847

Inventors:

Kenneth H. Heffner - Largo FL
Curtis W. Anderson - Largo FL

Assignee:

Honeywell Inc. - Minneapolis MN

International Classification:

C23C 412

US Classification:

427448

Abstract:

Protective and security coatings are applied to an integrated circuit by periodically passing the integrated circuit through a flame spray containing molten particles of the coating composition. The integrated circuit is attached to a fixture that is cooled with a coolant that is applied to the integrated circuit. The distance between the flame spray gun and the integrated circuit is controlled so that the particles are molten when they strike the circuit but the circuit heating is minimized. A flame resistant mask retains the integrated circuit on the fixture. The mask is constructed of a low thermally conductive material and the fixture is constructed of a high thermally conducive material.

Process For Coating An Integrated Circuit Device With A Molten Spray

US Patent:

5877093, Mar 2, 1999

Filed:

Oct 27, 1995

Appl. No.:

8/549351

Inventors:

Kenneth H. Heffner - Largo FL
Curtis W. Anderson - Largo FL

Assignee:

Honeywell Inc. - Minneapolis MN

International Classification:

H01L 2156

US Classification:

438761

Abstract:

Disclosed is a method of forming a primer coating and an opaque coating on an integrated circuit or multichip module. First a primer coating composition is applied to a surface of the integrated circuit device or multichip module to form a primer coating that increases the resistance of the surface to thermal and mechanical damage that may occur as a result of the application of the opaque coating. An opaque coating composition is then heated to a molten state and the molten opaque coating composition is applied over the primer coating to form an opaque coating that overlies active circuitry on the surface, to prevent optical and radiation based inspection and reverse engineering of the active circuitry.

Wear-Resistant Electrically Conductive Body

US Patent:

7344760, Mar 18, 2008

Filed:

Sep 12, 2003

10/662162

Inventors:

Kenneth H. Heffner - Largo FL, US
Charles W. Reed - Blacksburg VA, US

C23C 14/48

US Classification:

427523, 427524, 4272497, 2041921

Abstract:

A method for making a wear-resistant electrically conductive body having an electrically conductive diamond-like carbon coating, by ion-accelerating copper ions from a copper ion source onto a negatively charged electrically conductive body, and simultaneously ion-accelerating diamond-like carbon ions from a separate carbon ion source onto the negatively charged electrically conductive body. Also a dual ion-beam process for depositing a wear-resistant diamond-like carbon coating on a negatively charged electrically conductive surface by using an ion-beam to stabilize ionized carbon atoms that have been ion-accelerated onto the negatively charged electrically conductive surface.
