  Fully internal and motional state controlled and individually manipulable
polar molecules are desirable for many quantum science applications leveraging
the rich state space and intrinsic interactions of molecules. While prior
efforts at assembling molecules from their constituent atoms individually
trapped in optical tweezers achieved such a goal for exactly one molecule, here
we extend the technique to an array of five molecules, unlocking the ability to
study molecular interactions. We detail the technical challenges and solutions
inherent in scaling this system up. With parallel preparation and control of
multiple molecules in hand, this platform now serves as a starting point to
harness the vast resources and long-range dipolar interactions of molecules.
