This paper is a study of three-dimensional (3D) micron/submicron fabrication with a continuous wave (CW) laser. The fabrication forms vertical and horizontal hollow tubes in a photoresist film with nonlinear optical properties. We controlled beam intensities and dose amounts to manipulate a reaction time constant of the photoresist; we fabricated the 3D hollows in high contrast.

Key words: CW laser, laser fabrication, photoresist, nonlinear optics, reaction time constant
