Advanced Macromolecular Resists (A3)

Thrust A3 is the chemistry workbench for advanced resist design.
Possible avenues to overcome the challenge of printing conductive resist materials.

Advanced resist design is required for 3D laser lithography (also known as Direct Laser Writing (DLW)). In close alignment with Thrust B1, we will provide the chemical tools to tackle the challenges that will allow us to implement the next generation 3D Additive Manufacturing processes as recently described here: https://onlinelibrary.wiley.com/doi/full/10.1002/anie.201704695.

The Thrust is guided by our efforts of fusing four chemical challenges into one resist. We wish to code free-standing sub-diffraction structures (in the sub-20 nm range) with two different colors of light. Such structures will carry predetermined materials properties, reaching from insulating to highly conducting as well as (bio-orthogonally) degradable. In alignment with Thrust B1, which provides the 3D laser lithography machine tools, the ultimate aim of Thrust A3 can be subdivided into four individual aims:

1) development of effective sub-diffraction resists, 2) degradable resists, 3) conductive resists, and 4) resists that can be orthogonally written with different colors of light, affording disparate material properties (multi-material resists).

Close alignment with the molecular building blocks designed in Thrust A1 will ensure that we meet the molecular targets. Ultimately, the technologies developed in A3 in conjunction with B1 are critically required to achieve nanometer sized functional features that are essential for the constructs of Research Area C.
