Abstract
Precise measurement on the RF return loss was performed for a microfabricated slow-wave structure. The interaction circuit was designed to operate at 100 GHz of W-band frequency. A deep reactive ion etching (DRIE) showed a good side-wall profile but inaccurately curved bottom surface. The result represents that the etch rate was strongly dependent on the mask-opening area, which caused a frequency shift of about 5%.
