Israel’s Prime Minister to offer US President Obama two nanoscale Declarations of Independence

President Barack Obama will receive his present of a nanoscale document containing the US and Israeli Declarations of Independence in Israel, according to a Mar. 19, 2013 news item by Kevin Hattori on phys.org,

In a ceremony to be held on Wednesday, March 20, [2013] in Jerusalem, Israeli Prime Minister Benjamin Netanyahu will present U.S. President Barack Obama with nano-sized inscribed replicas of the Declarations of Independence of the United States and the State of Israel. Created by scientists at the Technion’s Russell Berrie Nanotechnology Institute (RBNI), at the request of PM Netanyahu, the Declarations appear side-by-side on a gold-coated silicon chip smaller than a pinhead. The juxtaposition symbolizes the shared values of both countries.

Hattori’s Mar. 18, 2013 news release for the American Technion Society (ATS), and the origin for the phys.org news item, provides this technical detail,

The area of the etched inscriptions is 0.04 square millimeters, and 0.00002 millimeters (20 nanometers) deep. The chip is affixed to a Jerusalem Stone dating to the Second Temple Period (1st Century BCE to 1st Century CE).

“This unique application of cutting-edge technology is just one example of Israel’s remarkable leadership in high-tech,” said Technion President Peretz Lavie.

The text was written using a focused ion beam (FIB) generator that shot tiny particles called Gallium ions onto a gold surface covering a base layer of silicon.  In a process that can be likened to digging a hole in the earth using a water jet, the ion beam etched the surface of the gold layer, making the underlying silicon layer visible.

The original image was translated into etching instructions using a special program developed for this purpose by Dr. Ohad Zohar, who conducted his Ph.D. under Prof. Uri Sivan of the Technion Physics Department. The engraving was done by Dr. Tzipi Cohen-Hyams, head of the RBNI Focused Ion Beam Lab. Other members of the team were Prof. Wayne D. Kaplan, Prof. Nir Tessler, Mr. Yaacov Shneider, Dr. Orna Ternyak, and Ms. Svetlana Yoffis.  The work was conducted in the Technion’s Sara and Moshe Zisapel Nanoelectronics Center and the Wolfson Microelectronics Research and Teaching Center.

Here’s what the chip looks like,
