                ON SEMICONDUCTOR APPOINTS CHIEF FINANCIAL OFFICER

         John T. Kurtzweil to lead company's global finance organization

PHOENIX, ARIZ. - MARCH 19, 2002 - ON Semiconductor (Nasdaq: ONNN) today
announced that it has appointed John T. Kurtzweil as senior vice president,
Chief Financial Officer (CFO) and Treasurer to lead the company's finance
organization as the company continues to execute on its strategy.

     Kurtzweil is a 23-year veteran of the high-tech industry and has held
numerous management positions of increasing responsibility in finance and
accounting during his career.

     Kurtzweil was most recently the senior vice president of finance and CFO at
Read-Rite Corporation, one of the world's largest independent suppliers of
magnetic recording heads for the hard disk drive (HDD) market. Prior to his
experience at Read-Rite, he held senior finance positions at Maxtor Corporation,
Miniscribe Corporation and Honeywell Incorporated.

     "John brings a wealth of experience in managing finance and accounting
operations for growing, global technology enterprises," said Steve Hanson, ON
Semiconductor president and CEO. "As the company continues to execute on its
long-range strategy, John's experience and proven leadership will play a key
role."

     ON Semiconductor's appointment of Kurtzweil is effective April 1. Kurtzweil
replaces Dario Sacomani, who was the company's CFO since it spun out of Motorola
in August 1999. Sacomani will assist in the leadership transition and will
announce his future plans at a later date.

     "We're tremendously grateful for Dario's contribution to ON Semiconductor,"
Hanson said. "Dario was instrumental in the successful start up of the company
and providing financial guidance during a time of great change and development
for the company."

     Kurtzweil earned his MBA at the University of St. Thomas and his bachelor's
degree in accounting from Arizona State University. He is a Certified Public
Accountant.
