How about a letterpress photomask?

Toppan photomask is a key material used in the semiconductor manufacturing process, which is characterized by high precision and high resolution. The main advantage of this material is that the film allows for the replication and transfer of fine patterns, which is important in the manufacture of highly integrated semiconductor chips.

Another advantage of letterpress photomasks is the film's customizable nature. Because each piece of the letterpress photomask is designed for a specific chip circuit, the film ensures that every detail of the fabrication process can be matched exactly to the circuit design.
