Through microphase separation, block copolymers (BCPs) can self-assemble into highly uniform, chemically distinct, periodic domains with dimensions and periods at scales of 3–200 nm 1,2 that are ...

There are still some problems to work out, such as cutting defect rates, but directed self-assembly has the potential to reduce the total number of masks. The upcoming 7nm process node presents tough ...

For the iCVD topcoat, divinylbenzene (DVB) was selected as the monomer for its ability to form robust organic networks of exceptionally low roughness 30. The iCVD ...

Imec has demonstrated the capability of directed self-assembly (DSA) to pattern line/spaces with a pitch as small as 18nm, using a high-chi block copolymer (high-χ BCP) based process under high volume ...

As previous articles in this series have shown, directed self-assembly may be a promising alternative for manufacturers seeking to shrink feature sizes in the face of a stalled exposure tool roadmap.

The European Commission has taken a consequential step in the early enforcement of the Digital Services Act (DSA). On 5 December 2025, the Commission imposed a €120 million fine on X (formerly Twitter ...
