Non-textured laser modification of silica glass surface: Wettability control and flow channel formation
Autor: Yuko Aono, Atsushi Hirata, Hitoshi Tokura
Publikováno v: Applied Surface Science. 371:530-537
Local wettability of silica glass surface is modified by infrared laser irradiation. The silica glass surface exhibits hydrophobic property in the presence of CF3 or (CH3)2 terminal functional groups, which are decomposed by thermal treatment, and de

Laser Modification of Silicon and Borosilicate Glass Wettability for Micro-Fluidic Systems
Autor: Yuko Aono, Wataru Shinohara, Hitoshi Tokura
Publikováno v: International Journal of Automation Technology. 9:668-673
A laser modification method to control the surface wettability of a silicon and borosilicate glass substrate is proposed and demonstrated. The wettability of the silicon surface decreases after 2.5 W laser irradiation without a change in surface morp

Experimental and numerical study of mechanism of glass modification process by continuous-wave laser backside irradiation (CW-LBI)
Autor: Hitoshi Tokura, Hirofumi Hidai, Sho Itoh
Publikováno v: Applied Physics A. 112:1043-1049
The modification of transparent materials using a femtosecond laser has been studied. We previously proposed a new method of modifying glass using a continuous-wave laser, named continuous-wave laser backside irradiation (CW-LBI), in which CW laser i

High-aspect-ratio Microdrilling with UV Laser Ablation. I
Autor: Hirofumi HIDAI, Sho ITOH, Hitoshi TOKURA, Seido NAGASAWA, Shigeru TACHIKAWA
Publikováno v: Journal of the Japan Society for Precision Engineering. 76:1161-1165
High-aspect-ratio microdrilling of borosilicate glass has been demonstrated by the forth harmonic of nanosecond Nd : YVO4 laser. In this paper, we investigated about the influence of the beam profile on the hole profile. Beam profile was changed by u

Glass Modification by Continuous-Wave Laser Backside Irradiation (CW-LBI)
Autor: Kuniaki Hiromatsu, Hitoshi Tokura, Hirofumi Hidai, Masato Yoshioka
Publikováno v: Appl. Phys. A. 96(No. 4):869-872
We report on a permanent change in the physical properties inside glass that is rapidly heated and quenched with a continuous-wave (CW) laser beam. The absorption of the glass was enhanced by laser heating, and the heated spot moved by thermal radiat

Blasting of Affected Layer of Silicon Surface Sliced by Wire EDM
Autor: Hirofumi Hidai, Taro Sugita, Hitoshi Tokura
Publikováno v: Advanced Materials Research. :440-444
Polycrystalline ingot slicing by wire electric discharge machining (W-EDM) has been investigated to reduce kerf loss and wafer thickness. In order to use the sliced wafers for semiconductor devices, the modified surface layer induced by W-EDM must be
