Motorola is expected to announce a rash of further job cuts next week when it posts its financial results.
But the company is playing down rumours that it is looking to ST Microelectronics (formerly SGS Thomson) to help bale it out on the semiconductor side.
The job cuts, according to reports, will be in addition to the 150,000 the company announced last June as part of its restructuring scheme.
Motorola is expected to announce the additional layoffs because both its semiconductor and mobile business are still in the doldrums.
Rumours that Motorola and ST Microelectronics will form a joint venture - with ST performing management functions and Motorola offering engineering expertise - were denied by a representative of the European company today.
He said: "These rumours have been flying around for some months time now. STM has made no statement about this."
