Ultrasonic Spraying of Photoresist for Glass

Ultrasonic Spraying of Photoresist for Glass – Cheersonic

In the case of spray coating, the resist film is deposited from atomised photoresist with typical droplet sizes in the μm range. The droplets are formed via, for example, a ultrasonic atomisation and land on the substrate surface carried by an air or nitrogen flow where they combine to form a closed resist film.

Possible Advantages
In addition to a very high resist yield (at least theoretically), the spray coating offers the potential to coat arbitrarily shaped substrates in which ultrasonic coating is not technically feasible or does not provide the results required with respect to homogeneity and edge coverage of the resist film over textures. For example, it is theoretically possible, in the case of textured substrates, to provide the grooves, sidewalls and edges of the textures with a uniform resist film thickness.
