      ON SEMICONDUCTOR ANNOUNCES FIRST QUARTER RESULTS AND PROVIDES SECOND
                                QUARTER GUIDANCE

            -   Total Revenues Up From Prior Quarter, Exceeds Guidance

            -   Backlog Up 12% From Prior Quarter

            -   Gross Margin Improved From 14% to 22% Sequentially

            -   EBITDA Up By $18 Million From Prior Quarter

PHOENIX, ARIZ. - APRIL 17, 2002 - - ON Semiconductor Corporation (Nasdaq: ONNN)
today announced that total revenues in the first quarter of 2002 were $269
million, a sequential increase from the fourth quarter of 2001, exceeding
previous guidance of sequentially flat to slightly down. The Company had a pro
forma net loss, excluding restructuring charges, of $43 million, or $0.26 per
share, in the first quarter of 2002, ahead of First Call's consensus loss
estimate of $0.31 per share. During the first quarter of 2002, restructuring
charges of $7 million were incurred primarily associated with previously
announced workforce reductions in Europe. Including restructuring charges, the
Company reported a net loss of $50 million, or $0.30 per share, in the first
quarter of 2002. EBITDA (as defined below) was $29 million in the first quarter
of 2002 as compared to $11 million in the fourth quarter of 2001.

     Gross margin improved to 22 percent in the first quarter, up from 14
percent in the prior quarter, as further cost reductions were realized and
factory utilization improved to over 65 percent in the first quarter from
approximately 50 percent in the fourth quarter of 2001. The Company is on track
to complete actions by the end of 2002 that it currently expects to generate
approximately $360 million of annualized cost savings, as compared to its cost
structure as of the first quarter of 2001. As of the end of the first quarter of
2002, the Company completed actions to achieve an estimated $290 million of
these savings.

     Backlog at the end of the first quarter of 2002 was $223 million, an
increase of $24 million from the end of fourth quarter of 2001. "The market
continues to provide us with strong indications of


                                                                               5

stabilization," said Steve Hanson, ON Semiconductor president and CEO. "We have
capitalized on this trend with an initiative targeting the PC market that
provides our customers with advanced analog ICs as well as the critical MOS
power devices to complete the system-level solution. Customers such as Astec,
Legend QDI and Samsung are designing our parts into some of their most advanced
offerings. To demonstrate our commitment to this market, we introduced several
exciting new devices. Using our MicroIntegration(TM) process, we introduced a
USB compatible protection filter. Alcatel is using this part in its latest DSL
modem. The success of this initiative spilled over into other markets as well.
This quarter, we announced significant design wins at TCL, China's largest
television manufacturer, and Hi-Tech, China's largest producer of PDAs."

    "We have become a different company over the course of the previous year and
strengthened our leadership team that will chart the direction of our new
company," Hanson added. "Syrus Madavi is now our executive chairman and chairman
of the board. John Kurtzweil has joined us as senior vice president, CFO and
treasurer and Bill Bradford recently came aboard as senior vice president of
sales and marketing. Our ability to attract this high-level talent clearly
reflects the great potential of our company. All of this is happening at the
right time; backlog is up from the prior quarter and consumer confidence is
rising. We are preparing for the increase in demand that we expect to follow."

    "Regarding our second quarter outlook, we expect revenues and margins to
show sequential improvement again with the continued strength of orders,
particularly in Asia, and further execution on our cost saving activities. We
anticipate total revenues to be between $270-$275 million in the second quarter
with gross margins increasing to 25-27 percent and operating expenses remaining
flat to slightly down from the first quarter. At these revenue and expense
levels for the second quarter, we expect to reduce the loss per share to
$0.20-$0.24. EBITDA is expected to be in the range of $45-$50 million." EBITDA
represents net income (loss) before interest expense, provision for income
taxes, depreciation and amortization expense, restructuring and other charges
and minority interests.

    "With improving financials and our continued focus on providing power and
data management solutions, we are excited about strengthening our competitive
position as the market begins to recover," Hanson said.
