The US Commerce Department said Tuesday a global survey of semiconductor chip producers and users shows a shortage will persist, sparked primarily by wafer production capacity constraints.

The voluntary survey of 150 companies last fall in the supply chain confirmed  "there is a significant, persistent mismatch in supply and demand for chips, and respondents did not see the problem going away in the next six months."

 Commerce Secretary Gina Raimondo told reporters that the department  "in a few instances didn't really get what we needed and we're going to go company by company and do personal engagement and get what we need."

Raimondo said in November that she had spoken to  "all of the CEOs in the supply chain - including Samsung, TSMC , SK - and all of the CEOs have pledged to me that they will be submitting robust and complete data flows to us."

 Some companies in Asia and governments had earlier expressed concern about the data request. Raimondo reiterated that the department could invoke its legal authority to get responses.

Taiwan's Economy Ministry, responding to the survey, reiterated that Taiwanese companies are working hard to produce chips and coordinating with  "important international business partners" to strengthen supply chains.
