June 20 (Reuters) - SoftBank Group founder

Masayoshi Son is envisaging setting up a $1 trillion industrial

complex in Arizona that will build robots and artificial

intelligence, Bloomberg News reported on Friday, citing people

familiar with the matter.

Son is seeking to team up with Taiwan Semiconductor

Manufacturing Co ( TSM ) for the project, which is aimed at

bringing back high-end tech manufacturing to the U.S. and to

create a version of China's vast manufacturing hub of Shenzhen,

the report said.

SoftBank officials have spoken with U.S. federal and state

government officials to discuss possible tax breaks for

companies building factories or otherwise investing in the

industrial park, including talks with U.S. Secretary of Commerce

Howard Lutnick, the report said.

SoftBank is keen to have TSMC involved in the project,

codenamed Project Crystal Land, but it is not clear in what

capacity, the report said. It is also not clear the Taiwanese

company would be interested, it said.

TSMC is already building chipmaking factories in the U.S.

with a planned investment of $165 billion.

Son is also sounding out interest among tech companies

including Samsung Electronics ( SSNLF ), the report said.

The plans are preliminary and feasibility depends on support

from the Trump administration and state officials, it said.

A commitment of $1 trillion would be double that of the $500

billion "Stargate" project which seeks to build out data centre

capacity across the U.S., with funding from SoftBank, OpenAI and

Oracle.

SoftBank and TSMC declined to comment. The White House and

U.S. Department of Commerce did not immediately respond to

requests for comment.

The proposed scheme follows a series of big investment

announcements SoftBank has made this year.

In March it announced it would acquire U.S. semiconductor

design company Ampere for $6.5 billion and in April said it

would underwrite up to $40 billion of new investment in OpenAI,

of which up to $10 billion would be syndicated to other

investors.

This week SoftBank raised $4.8 billion from a sale of shares

in T-Mobile.
