Sw. Moon et al., TERAHERTZ WAVE-GUIDE COMPONENTS FABRICATED USING A 3D X-RAY MICROFABRICATION TECHNIQUE, Electronics Letters, 32(19), 1996, pp. 1794-1795
A novel process using embedded x-ray masks that allows the fabrication
of 3D terahertz waveguide components is demonstrated. X-rays produced
by a laser plasma source are used to expose a chenically amplified re
sist. To produce structures with the required depth (similar to 50 mu
m) a cyclic exposure and development technique is used. A representati
ve waveguide cavity intended for operation at 2.5THz is realised.
