                             OF SENIOR SECURED NOTES


PHOENIX, ARIZ. - APRIL 17, 2002 - ON Semiconductor Corporation (NASDAQ: ONNN)
today announced that it and its wholly-owned subsidiary, Semiconductor
Components Industries, LLC, intend to issue approximately $300 million principal
amount of senior secured notes due 2008 in a Rule 144A private offering.

     ON Semiconductor plans to use the net proceeds from the offering to prepay
a portion of Semiconductor Components' term loans under its senior bank
facilities. ON Semiconductor and Semiconductor Components have obtained an
amendment to their senior bank facilities to permit the issuance of the senior
secured notes. The sale of the senior secured notes is expected to close prior
to May 10, 2002.

     The senior secured notes will be offered to qualified institutional buyers
in reliance on Rule 144A of the Securities Act of 1933 and to non-U.S. persons
in reliance on Regulation S under the Securities Act of 1933. At the time of the
offering, the senior secured notes will not be registered under the Securities
Act of 1933. Therefore, the senior secured notes may not be offered or sold
absent registration under the Securities Act of 1933 or an exemption from the
registration requirements of the Securities Act of 1933 and applicable state
securities laws.

     This news release does not and will not constitute an offer to sell or the
solicitation of an offer to buy the senior secured notes, nor shall there be any
sale of the senior secured notes in any state in which any such offer,
solicitation or sale would be unlawful prior to the registration or
qualification under the securities laws of any such state. This news release is
being issued pursuant to and in accordance with Rule 135c under the Securities
Act of 1933.
