Note 1: Unless otherwise stated, all financial figures discussed in this
announcement are prepared in accordance with ROC GAAP, which differ in some
material respects from generally accepted accounting principles in the United
States. They are un-audited, unconsolidated, and represent comparisons among
the three-month period ending March 31, 2009, the three-month period ending
December 31, 2008, and the equivalent three-month period that ended March 31,
2008. For all 1Q09 results, New Taiwan Dollar (NT$) amounts have been

United Microelectronics Corporation (NYSE: UMC; TSE: 2303) ("UMC" or "the
Company"), a leading global semiconductor foundry, today announced its
unconsolidated operating results for the first quarter of 2009. Revenue
decreased 41.5% quarter-over-quarter to NT$10.84 billion, from NT$18.54
billion in 4Q08, and decreased 54.8% year-over-year from NT$24 billion in
1Q08.
Gross margin for the quarter was -40%, operating margin was -67.5%. Net loss
in 1Q09 was NT$8.16 billion, with loss-per-share at NT$0.64.
Dr. Shih-Wei Sun, CEO of UMC said, "Q1 2009 was challenging for UMC, due
to a sharp drop in customer demand caused by the global economic downturn. As
a result, UMC's wafer shipments for the quarter dropped to 384 thousand 8-inch
equivalent wafers with utilization rate at 30%. UMC also reported higher
operating costs associated with the adoption of ROC SFAS No.10, resulting in
gross margin of -40%. Despite these factors, UMC remained financially solid in
Q1, maintaining positive free cash flow of NT$2.18 billion and cash
equivalents at NT$35.91 billion. However, recent orders indicate strong demand
for Q2, confirming our assessment from last quarter's conference that demand
had already bottomed out. UMC expects Q2 revenues to grow significantly with
loss turning to profit. Moreover, we are optimistic about the longer-term
prospect of the foundry industry and demand growth. As global economic
uncertainties continue, we will closely watch our customers' inventory
consumption, end market demands and the introduction of new applications so
that we can quickly respond to any status changes when necessary."
Dr. Sun continued, "With regard to UMC's recent rush orders, we will work
diligently to meet urgent order deliveries for these customers. However, our
mid- to long-term capacity plans, including capacity conversion to a more
favorable technology mix, 45/40nm ramp to 300mm volume production and
acquiring the most advanced R&D equipment, are all in progress and fully
capable of satisfying our customers' manufacturing requirements."
"UMC's advanced R&D efforts and equipment upgrades will proceed as planned
despite economic uncertainties to continuously bolster our long-term
competitiveness. For example, we have already delivered customer ICs
manufactured on UMC's independently developed high performance 40nm process.
The large die-size programmable logic chips are being produced with excellent
cycle time and yields. Many other customer 45/40nm designs will enter pilot
and verification stages later this year, further contributing to UMC's
financial performance when these designs enter volume production. With regard
to more advanced 28nm process technology, with several customers involved in
the current development stage, we are progressing smoothly at UMC's R&D center
in Tainan. For this technology node, UMC will provide low power and high
performance Poly/SiON and HK/MG process technologies to meet the performance
and power needs of various applications."
Recently, two global semiconductor companies, one from Taiwan and another
from the USA, awarded UMC with honors of "2008 Best Fab Award" and "2008
Supplier Excellence Award", respectively. This recognition underscores UMC's
strategy of delivering "Customer-Driven Foundry Solutions" to create a win-win
situation for UMC and its customers.

Revenue decreased 41.5% QoQ to NT$10.84 billion, from NT$18.54 billion in
4Q08, and decreased 54.8% YoY, from NT$24 billion in 1Q08. Weakening global
semiconductor demand was the key reason for the decrease in revenue. Gross
loss was NT$4.34 billion, or 40% of revenue, compared to NT$0.8 billion, or
4.3% of 4Q08 revenue. Operating loss for the quarter was NT$7.32 billion, or
67.5% of revenue, compared to NT$3.88 billion, or 20.9% of 4Q08 revenue.
Except for weakening demand, the weaker gross margin and operating margin in
the first quarter also attributed to the adoption of ROC SFAS No.10, which
requires fixed production costs allocated to idle capacity to be accounted for
in COGS if actual loading is lower than normal capacity and "Loss on decline
in market value and obsolescence of inventories" (LCM) to be accounted for in
COGS instead of Non-operating expenses. Net loss in 1Q09 was NT$8.16 billion,
compared to NT$23.51 billion in 4Q08.
Loss per ordinary share for the quarter was NT$0.64. Loss per ADS was
US$0.094. One ADS represents five Taiwan-listed ordinary shares. The basic
weighted average number of outstanding shares in 1Q09 was 12,767,114,132,
compared with 12,971,740,926 shares in 4Q08 and 13,171,692,578 shares in 1Q08.
The diluted weighted average number of outstanding shares was 12,767,114,132
in 1Q09, compared with 12,971,740,926 shares in 4Q08 and 13,418,161,562 shares
in 1Q08. The fully diluted share count on March 31, 2009 was 13,576,836
thousand. On March 31, 2009, UMC held 300,000 thousand treasury shares
acquired from the 13th share buy-back program. UMC completed the 13th share
buy-back program on February 16, 2009.

Depreciation and amortization expenses totaled NT$8.64 billion in 1Q09,
compared to NT$9.15 billion in 4Q08. Depreciation within CoGS decreased by
9.2% to NT$6.97 billion. Following the adoption of ROC SFAS No. 10 in 1Q09,
CoGS was higher than if the new rule had not been adopted. General and
administration expenses increased to NT$529 million, mainly due to the
increase in professional fees. Sales & marketing expenses dropped to NT$632
million in connection with the decrease in IP amortization. R&D expenses
decreased to NT$1,821 million due to the expense control activities in 1Q09.
As a result, total operating expenses decreased 2.9% to NT$2.98 billion. The
total R&D expense was 16.8% of revenue in 1Q09.

Net non-operating losses during 1Q09 were NT$843 million. Net investment
losses were NT$1.08 billion, including NT$599 million of investment losses
accounted for under the equity method and a NT$523 million loss from valuation
of ProMos shares. The exchange gain of NT$255 million was partially offset by
the valuation loss of forward contract. Therefore, the net exchange gain was
NT$78 million.

The investing cash outflow primarily reflects the CAPEX in 1Q09 of NT$1.57
billion. The NT$2.39 billion of financing cash outflow was from the purchase
of treasury stock in the 13th share buy-back program. Free cash flow (Note 2)
for 1Q09 was NT$2.18 billion. Over the next 12 months, UMC will not need to
repay any term loans.

The percentage of revenue from the communication segment decreased to 57%
of total revenue in 1Q09 due to decreasing demand for communication chips,
especially in wireline products.
Note 3: Revenue in this section represents wafer sales.

Blended Average Selling Price Trend
The blended average selling price (ASP) decreased by 10% in US dollar
terms during 1Q09, due to a larger portion of the process technology mix
coming from older process generations as well as short-term volume discounts
to customers.

capacity remained the same as from Q408. The total estimated installed
capacity in 2Q09 also remains unchanged, although 65nm capacity is increasing
due to internal capacity conversion and 8-inch wafer capacity moving to more
advanced nodes.
