So, it's not the world's smallest

Finally got the right disclosure from Agence France-Presse

The Malaysia Microchip was released after more than two years of research
and development. The smallest version measures 0.7 millimeters by 0.7
millimeters, according to officials.
Costing six cents each, three versions of the chip were developed after the Malaysian government in 2003 bought the technology and the rights to design, manufacture and market the chip from Japan's FEC Inc.

So it's not the World's smallest, not even smaller than the original mu-chip from Hitachi
I'd like to see less feel good spin.
