Akrion Inc., an Allentown, Pa.-based provider of batch-immersion and single-wafer wet cleaning systems for the semiconductor industry, has withdrawn registration for a proposed $50 million IPO. The company blamed “current market conditions,” even though the original S-1 form had been filed in 2004. The company lists Sunrise Capital Partners and Westar Capital Partners as significant shareholders. www.akrion.com< ?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
