Abstract

Near-field microprobes with high optical transmittance for optical recording and multi-probes with a metal wire as a heater for thermal recording were fabricated by silicon micromachining. Pyramidal etch pits were defined on Si(100) wafer by oxidation, lithography, SiO₂ patterning and Si etching with tetramethyl ammonium hydroxide (TMAH). The aperture showed a high optical transmittance due to a large opening angle in the SiO₂ tip. Micro-thermal probe array based on atomic force microscopy (AFM) were fabricated and evaluated. The total recording speed for the device was found to be 300 Mbits/sec.
