PATTERN FORMING METHOD AND PLASMA PROCESSING METHOD
A pattern forming method includes forming a pattern film on a substrate. The pattern film includes a triptycene derivative having a triptycene skeleton. The triptycene skeleton includes a first plane in which position 1, position 8, and position 13 of the triptycene skeleton are arranged, and a second plane in which position 4, position 5, and position 16 of the triptycene skeleton are arranged. The triptycene derivative includes a first side chain on a one plane side, the one plane side being on a side of one plane from among the first plane and the second plane, and a second side chain on another plane side or on the one plane side, the another plane side being on a side of another plane from among the first plane and the second plane. The second side chain is different from the first side chain in an etching selectivity ratio.
