NEW TAIPEI, Taiwan, April 27 (Reuters) - A Taiwan court

on Monday fined the local unit of Japan's Tokyo Electron

T$150 million ($4.78 million) and sentenced defendants

to up to 10 years in jail in a trade secrets case involving the

alleged theft of TSMC's sensitive chip technology.

The ruling marks one of Taiwan's most high-profile cases

involving alleged breaches of national core technologies, after

prosecutors charged Tokyo Electron's ( TOELF ) Taiwan unit under the

National Security Act.
