The resistance of poly(butene-1 sulfone) (PBS) to CF4 and oxygen reactive ion etching is greatly enhanced by low power nitrogen plasma pretreatment. The original thickness of PBS can be maintained.

In this paper, two new near one-pass packet-routing schemes are proposed to tolerate all single faults among the switching boxes or the connecting links respectively in a unique-path multistage Omega network. Working in an undirected network, our results can compete with the two-pass routing scheme, which works in a directed network, proposed by Varma.

Poly(butene-1 sulfone) (PBS), a sensitive e-beam and X-ray resist, is inert to UV light. We found that the addition of a small amount of photoacid, triphenylsulfonium hexafluoroarsenate (TPSHFA), to PBS can catalyze its main chain scission via C-S bond cleavage by 254 nm deep UV exposure and concurrent baking at 80-degrees-C. Therefore, PBS can be used as a deep UV positive resist. The chemistry and resist characteristics of the PBS + TPSHFA system are discussed.
