    摘要: An etching apparatus comprises a chamber; a substrate supporter in the chamber; a substrate disposed on the substrate and having one of a notch zone and a flat zone, the substrate having a rim of a circular shape except in the one of the notch zone and the flat zone, wherein the rim of the substrate has a dented shape in the notch zone and a chord shape in the flat zone; a substrate-screening unit having a substantially same shape as the substrate and disposed over the substrate, the substrate-screening unit having a portion corresponding to the one of the notch zone and the flat zone, wherein the substrate-screening unit has a first diameter smaller than or equal to a second diameter of the substrate; a gas injection means supplying gases onto a periphery of the substrate; and a power supply unit supplying an RF (radio frequency) power into the chamber.

    摘要: The present invention relates to a method of forming an etching mask. According to the present invention, there is provided a method of forming an etching mask, comprising the steps of: depositing a hard mask film containing silicon on a substrate; depositing a photoresist on the hard mask film; patterning the photoresist; and etching the hard mask film using the photoresist pattern as an mask and using an etching gas including a CHxFy(x, y=1, 2, 3) gas. At this time, an etch selectivity of the hard mask film to the photoresist pattern can be increased using a mixed gas including CH2F2 and H2 gases when etching the hard mask film under the photoresist pattern used in a wavelength of 193 nm or less.
