AMSTERDAM, May 27 (Reuters) - French semiconductor

materials supplier Soitec on Tuesday withdrew forecast

targets for its new fiscal year and the medium term, following a

multi-year slump in automotive and industrial chip demand.

The group will only guide on a quarterly basis, it said in a

statement, citing poor visibility and uncertainty across all of

its markets.

It expects first-quarter revenue to fall 20% year-on-year at

constant exchange rates, against the 121 million euros ($137.1

million) it reported last year.
