Directed self-assembly

{
  "id": "MLC-T-CHM-003265",
  "term": "Directed self-assembly",
  "field": "Chemistry",
  "definition": "A process where block copolymers or other self-assembling materials are guided by an external template to form ordered nanoscale patterns. The template provides a pre-pattern that directs the orientation and registration of the self-assembled structures. This technique is explored for creating high-resolution patterns in semiconductor manufacturing, exceeding the limits of conventional lithography.",
