The American Electronics Association (AeA) reported that about 560,000 jobs have been lost from the height of the dotcom era over the past two years.
The majority of those positions were lost in the manufacturing industry which shed 415,300 jobs between January 2001 and December 2002.
High-tech manufacturing companies included PC and server suppliers, semiconductor companies, consumer electronics companies and medical equipment makers, said William Archey, president and chief executive officer of the AeA.
The decline in manufacturing jobs was one of the biggest surprises of the survey, as the AeA did not expect such a steep decline in the manufacturing sector.
The number of workers in communications services positions, such as telecommunications workers, fell by 135,300.
"The telecom sector remains very moribund, with almost everything in wireless or telecommunications taking a big hit," Archey said.
However, the software services industry managed to add 5,300 jobs. Companies such as SAP and Oracle make up the software services industry, which reflects the increased importance of enterprise software to corporations, the report said.
The AeA is a trade association made up of more than 3,000 high-tech companies.
