Fabrication Techniques:

Photolithography: A critical process in ultra-small pitch substrate fabrication, photolithography uses light to transfer intricate patterns onto the substrate. Advanced photomasks and optical systems enable the creation of sub-micron features with exceptional precision.

Electron-Beam Lithography: Offering sub-nanometer resolution, electron-beam lithography is invaluable for creating ultra-small features. A focused electron beam is used to expose the resist, allowing for the generation of complex patterns at an unprecedented scale.

Deposition and Etching: Thin-film deposition and etching processes are employed to build up the layers of the substrate. Techniques like chemical vapor deposition (CVD) and physical vapor deposition (PVD) deposit thin metal films and insulating layers. Etching processes, including reactive ion etching (RIE) and plasma etching, are used to selectively remove material and define patterns.

Electroplating: Electroplating is utilized to form metallic traces and interconnects. It enables the creation of fine and densely packed features by depositing metal onto a template, replicating the desired pattern.

Materials Selection:
BT Base Materials. High Base Materials.ABF Base Materials. and other High TG base materials. Or High speed and high frequency materials.
