Solutions bringing electronics within the reach of everyone

With its "Solutions for electronics" innovation platform, Arkema has positioned itself as a key player upstream of this sector, and so contributes to the United Nations Sustainable Development Goal (SDG9) "Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation".

The major societal challenge of this SDG is durable industrialization. Information technology and electronics are key elements of this by allowing industries in developed countries to optimize their manufacturing resources and their logistics.

The evolution of products in the electronics sector must also help provide access to information and communication technologies to all populations in developing countries which still lack them, i.e. over 4 billion people today.

Materials for sturdier devices

Electronics applications are characterized by the high frequency of new solutions being brought to market and their strong growth.

 

With its range of Technical Polymers, Arkema offers solutions for the smartphone and tablet segments which help extend their lifetime while lowering their manufacturing cost.

The Group has developed a PVDF Kynar® grade used in the batteries of smartphones and tablets to bind the various electrode components in order to optimize their power and durability.

Another of its polymers is the Rilsan Clear® polyamide used to manufacture particularly sturdy, lightweight and fine smartphone structures for tougher and more durable devices.

Nanolithography pushes the boundaries of optical lithography

Optical lithography is the current process for engraving the structures of microprocessors and memories by optical projection on silicon.

 

The process has now reached its limits given the minute size of the etchings, namely a few tens of nanometers.

Arkema has developed the Directed Self Assembly (DSA) technology which, on a nanometric scale, helps assemble the molecules of polymers to form patterns on the surface of the silicon, which will then become electronic contacts.

 

This innovation in improving the miniaturization and performances of silicon chips offers promising prospects in increasing the storage capacities of microprocessors – a key element in the development of information technology – and in reducing their production costs.
