Definitions
- the temperature of the support for supporting the substrate in the processing container is 0 to 20 ° C.
- the substrate may have a surface layer to be etched under the lower film using the lower film as a mask.
- FIG. 5 is a cross-sectional view for explaining a remaining shoulder portion.
- the gate valve 38 is opened, and the wafer W is loaded into the processing container 2 and placed on the susceptor 3. Thereafter, the gate valve 38 is closed, the susceptor 3 is raised, and the distance between the wafer W surface on the susceptor 3 and the shear head 21 is adjusted to about 30 to 90 mm. Then, the inside of the processing container 2 is exhausted by the exhaust device 36 to reduce the pressure. Thereafter, a DC voltage is applied from the DC power supply 13 to the conductor 12 in the electrostatic chuck 11.
- the organic material film 64 is etched by the plasma of the generated etching gas. At this time, a high frequency power of a predetermined frequency is applied from the high frequency power supply 50 to the susceptor 3 as the lower electrode so that ions in the plasma are drawn into the susceptor 3 side.
- the flow rate ratio between NHs gas and O 2 gas is adjusted so that a desired CD shift value is obtained.
- the organic material film 64 can be etched with a high selectivity with respect to the photosensitive resist film 63 using only NH 3 gas. However, if only NH 3 gas is used, the etching tends to be insufficient, and the width of the etched portion tends to be narrow, so that a good CD shift value cannot be obtained. Also, etching residues tend to remain. In contrast, more adding an appropriate amount of 0 2 gas, etching is accelerated, it is possible to obtain a desired CD shift value. In addition, etching residues can be hardly generated.
- Etching is performed under the conditions above, and it is 10 to 3 with respect to the time J until the organic material film 64 is completely etched. The etching is terminated when the time of 0 ° / 0 over-etching has elapsed.
- the pressure inside the processing vessel was set to 2.7 Pa, and as an etching gas, O 2 gas: 0.05 L / min, (A) N 2 gas: 0.05 L / min and (B) C ⁇ gas : Etching was performed by adding any of 0.05 L / min and keeping all other conditions the same.
- the CD shift values were as large as (A): center: +132 nm, edge: +133 nm, (B): center: +79 nm, edge: +72 nm, both large. Poing had also occurred.
