Taiwan semiconductor companies in the field of back-end packaging and testing are under double pressure in maintaining their world's leading position in the industry, facing a growing demand for improved technology while China threatens to seize global market share.
The packaging and testing industry plays a key role in back-end semiconductor manufacture. With improving technologies pushing the front-end silicon wafer manufacturing process from 0.25 micrometers to 90 nanometers and even to 60nm and 45nm, the sector in Taiwan is also faced with the challenge of technological improvement.
It is essential for companies that do not want to be knocked out of the business to overcome their technological barriers and take advantage of the demand for "fine pitch" packaging services from leading wafer fabricators.
The existence and market prospects of the packaging and test sector -- an indispensable back-end semiconductor manufacture process -- is closely bound up with integrated circuit (IC) production.
According to statistics compiled in the Industrial Technology Intelligence Services (ITIS) program under the Ministry of Economic Affairs, the output value of Taiwan's IC industry broke the NT$1 trillion (US$30.09 billion) mark to reach NT$1.99 trillion in 2004, representing growth of 34.2 percent over the previous year.
Some NT$156.5 billion of that amount was the output value of the IC assembly industry, while NT$57.7 billion was from the test sector. The two figures recorded year-on-year growth of 33 percent and 41 percent, respectively.
It has been assessed that the output value of Taiwan's IC manufacturing industry will surge to NT$1.279 trillion in 2005, while that of the packaging sector will rise to NT$178.1 billion at an expected annual growth rate of 13.8 percent, and that of the test sector will increase to NT$67 billion at a growth rate of 16 percent.
Historically, semiconductor companies designed, manufactured, packaged and tested IC chips in their own integrated device manufacture (IDM) facilities. As the industry expands under strong market demand, a trend is also growing for these companies to outsource stages of the manufacturing process, enabling them to focus on their core competencies such as design and integration, and meet increasing demand.

After development of nearly two decades, a complete up-mid-down stream of supply chain system was formed in Taiwan's semiconductor manufacturing industry. But in the economic recession between 2000 and 2001, a large-scale company reshuffle occurred in the back-end packaging and test market. Weak companies were either integrated or bought out by foreign or domestic enterprises.
Thus, professional and international IC assembly and test service providers emerged. The Kaohsiung-headquartered Advanced Semiconductor Engineering Inc (ASE,

Meanwhile, thanks to fast expansion of the industry in the manufacture of thin film transistor-liquid crystal displays (TFT-LCDs), the demand for driver ICs has surged in the past few years, leading to a boom in orders for driver IC packaging and test services. Driver ICs are one of basic key components of LCD displays.

With international IDM giants and semiconductor makers forced to outsource back-end lines to preserve their core competitiveness due to the evolution of the semiconductor manufacturing process toward the more sophisticated and delicate "nano" level, a market worth billions of US dollars exists for Taiwanese providers of packaging and test services.
TARIFF TRADE-OFF: Machinery exports to China dropped after Beijing ended its tariff reductions in June, while potential new tariffs fueled ‘front-loaded’ orders to the US The nation’s machinery exports to the US amounted to US$7.19 billion last year, surpassing the US$6.86 billion to China to become the largest export destination for the local machinery industry, the Taiwan Association of Machinery Industry (TAMI, 台灣機械公會) said in a report on Jan. 10. It came as some manufacturers brought forward or “front-loaded” US-bound shipments as required by customers ahead of potential tariffs imposed by the new US administration, the association said. During his campaign, US president-elect Donald Trump threatened tariffs of as high as 60 percent on Chinese goods and 10 percent to 20 percent on imports from other countries.
Taiwanese manufacturers have a chance to play a key role in the humanoid robot supply chain, Tongtai Machine and Tool Co (東台精機) chairman Yen Jui-hsiung (嚴瑞雄) said yesterday. That is because Taiwanese companies are capable of making key parts needed for humanoid robots to move, such as harmonic drives and planetary gearboxes, Yen said. This ability to produce these key elements could help Taiwanese manufacturers “become part of the US supply chain,” he added. Yen made the remarks a day after Nvidia Corp cofounder and chief executive officer Jensen Huang (黃仁勳) said his company and Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) are jointly
United Microelectronics Corp (UMC, 聯電) expects its addressable market to grow by a low single-digit percentage this year, lower than the overall foundry industry’s 15 percent expansion and the global semiconductor industry’s 10 percent growth, the contract chipmaker said yesterday after reporting the worst profit in four-and-a-half years in the fourth quarter of last year. Growth would be fueled by demand for artificial intelligence (AI) servers, a moderate recovery in consumer electronics and an increase in semiconductor content, UMC said. “UMC’s goal is to outgrow our addressable market while maintaining our structural profitability,” UMC copresident Jason Wang (王石) told an online earnings
MARKET SHIFTS: Exports to the US soared more than 120 percent to almost one quarter, while ASEAN has steadily increased to 18.5 percent on rising tech sales The proportion of Taiwan’s exports directed to China, including Hong Kong, declined by more than 12 percentage points last year compared with its peak in 2020, the Ministry of Finance said on Thursday last week. The decrease reflects the ongoing restructuring of global supply chains, driven by escalating trade tensions between Beijing and Washington. Data compiled by the ministry showed China and Hong Kong accounted for 31.7 percent of Taiwan’s total outbound sales last year, a drop of 12.2 percentage points from a high of 43.9 percent in 2020. In addition to increasing trade conflicts between China and the US, the ministry said
