Paper Abstract

Fabrication of 3D terahertz waveguide components is demonstrated using a novel x-ray micromachining process with integral and embedded x-ray masks. 1 nm x-rays generated by a laser-plasma source are used to expose chemically amplified resist. A repeated exposure and development technique shortens the total x-ray exposure time to 10 min to obtain the required 48 micrometers high structures. A 2.5 THz waveguide cavity is fabricated in gold by electroplating the above resist microstructure.
