Intersil Celebrates Tenth Anniversary

MILPITAS, CA--(Marketwire - August 13, 2009) - Intersil
Corporation (NASDAQ: ISIL), a world leader in the design and
manufacture of high-performance analog and mixed-signal
semiconductors, today is celebrating the 10th anniversary of its
rebirth as an independent company. On Friday, August 13, 1999, Intersil
was officially spun-off from Harris Corporation and became a standalone
semiconductor enterprise. Just six months after the spin-out, Intersil
joined the NASDAQ and completed the largest semiconductor Initial Public
Offering (IPO) at that point in history.

"Thanks to their exceptional dedication and contributions, the people of
Intersil have propelled this company, in a very short period of time, to
become one of the most respected companies in the semiconductor industry,"
said David Bell, CEO. "Over the past several years our revenue growth has
consistently out-paced our peers, resulting in solid financial results, a
very strong balance sheet, and a long line of technology breakthroughs.
Intersil's future is very bright, and we look forward celebrating even
greater accomplishments ten years from today."

During the last decade, Intersil has established itself as one of the
premier high-performance analog companies in the semiconductor
industry. Today the company has approximately 1500 employees worldwide,
wafer fabrication facilities in Palm Bay, Florida, and regional offices in
every key market around the globe. The company also has 13 design centers,
approximately 50 highly differentiated product lines, and is the world's
leading supplier of power management solutions for personal computing. The
company creates products for four key end-user market segments:
communications, computing, industrial and consumer devices.

Intersil has a history of aggressive expansion through both organic growth
and strategic acquisitions. During the past year the company has made four
important acquisitions that have substantially expanded its portfolio of
audio, power, data conversion and networking products.
