Applied Materials had six patents in connectivity during Q1 2024. The patent filed by Applied Materials Inc in Q1 2024 relates to introducing an encapsulation material into an optical device to achieve a consistent thickness distribution at eyepiece areas on a substrate. This helps reduce variation in substrate thickness from substrate to substrate. The use of maskless patterning techniques like gray-tone lithography and inkjet printing eliminates the need for additional processing steps. The encapsulation material also serves to protect the index-matched layer from damage.

Application: Method for integration of optical device fabrication with substrate thickness engineering (Patent ID: US20240094440A1)
The patent filed by Applied Materials Inc. relates to introducing an encapsulation material into an optical device to achieve a consistent thickness distribution at eyepiece areas across a substrate. This uniform distribution reduces thickness variation between substrates and eliminates the need for additional processing steps. The encapsulation material protects the index-matched layer from damage, ensuring the longevity of the optical device.
The optical device described in the patent includes a substrate with varying depth, an index-matched layer, optical device structures, and an encapsulation material. The encapsulation material has a refractive index matching that of the substrate and index-matched layer, ensuring optical consistency. The method of forming the optical device involves patterning the index-matched layer using techniques like gray-tone lithography and inkjet printing, followed by the deposition of the encapsulation material and optical device film. The process results in a device with consistent structure height and optimal performance characteristics.
