* Europe’s STOXX 600 flat
* Micron China chip sale ban hits semiconductor makers
* Money-laundering case weighs on Danske Bank (Adds closing prices)

LONDON, July 4 (Reuters) - European shares traded flat on Wednesday as worries over global trade persisted, with sentiment towards semiconductor stocks in particular souring after Micron Technology was banned from selling chips in China.
The pan-European STOXX 600 index closed flat with Germany’s exporter-heavy DAX and the UK’s FTSE 100 falling both 0.3 percent.
Trading has been choppy before a July 6 deadline when the United States is set to impose tariffs on $34 billion worth of goods from China.
The tit-for-tat saga has hit market sentiment in recent weeks. News a Chinese court temporarily banned Micron Technology from selling chips in China, the world’s biggest memory chip market, hit semiconductor stocks.
“The biggest risks to the technology sector are regulation and global semiconductor disruption from an escalating trade war,” Peter Garnry, head of equity strategy at Saxo Bank, said.
Europe’s tech sector fell 1.4 percent, the worst sectoral performance. Chipmaker STMicro was down 3 percent and Infineon 1.8 percent. Silicon wafer-maker Siltronic dropped 7 percent.
Recent guidance cuts from BE Semiconductor and Osram Licht have also weighed on sentiment around the sector, which has fallen more than 9 percent since June’s 17-year high.
Smaller Swiss stock Comet, whose business focuses on X-ray and radio frequency technology, issued a sales and profit warning for 2018 and saw its shares plunge nearly 20 percent.
Elsewhere, shares in Danske Bank were down about 2 percent. A report citing fresh data in the bank’s Estonian money-laundering case suggested its extent was greater than previously reported.
Danske Bank head of group compliance, Anders Meinert Jorgensen, said: “... we have indicated on several occasions that the extent appears to be somewhat bigger than what has previously been reported”.
More broadly, gains across defensive sectors limited losses on the STOXX. Telecoms rose 1.8 percent and utilities 0.6 percent. (Reporting by Kit Rees and Julien Ponthus Editing by Alison Williams)
