【NIKKEI ASAIN REVIEW】 Silicon wafer recycler goes public with high hopes for electric car boom

 Silicon wafer recycler goes public with high hopes for electric car boom

Taiwan's Phoenix Silicon raises over $12m on IPO

CHENG TING-FANG, Nikkei staff writerJuly 10, 2018 13:41 JST

TAIPEI -- Phoenix Silicon International, a niche provider of services for chipmakers, made its Taiwanese stock market debut on Tuesday with high hopes for demand related to electric cars and mainland China's growing semiconductor industry.

The company's shares surged more 60% from their offer price of 24.60 New Taiwan dollars after trading began Tuesday morning, hitting NT$39.8 at one point. That puts the market value of the Hsinchu-based company at more than NT$5.26 billion ($173.89 million), vastly exceeding the NT$383 million it would have raised at the offer price.

Though little known outside the semiconductor industry, Phoenix Silicon plays an essential role in the chip supply chain. The company provides wafer recycling services to top global contract chipmakers such as Taiwan Semiconductor Manufacturing Co. and United Microelectronics Corp., while its growing wafer thinning business counts automotive chip leaders like Infineon Technologies, Texas Instruments and ON Semiconductor as clients.

The high cost of silicon wafers -- the substrates on which chips are manufactured -- spurs chipmakers to use reclaimed wafers for tests to optimize and monitor production processes. Such wafers can be reused several times, reducing costs.

Wafer thinning is crucial to improving the efficiency of all kinds of power management chips, said Mike Yang, chairman of Phoenix Silicon.

"We see strong growth momentum from power-management-related chips for future connected and electric cars and various industrial applications for years to come," Yang told reporters.

As for wafer reclaiming, Phoenix looks to China "as foreign and local chipmakers are all expanding production there to catch the rapidly growing market," Yang said.


Phoenix Silicon International sees plenty of growth potential in China's semiconductor industry, says Chairman Mike Yang.


The Taiwanese company is also keen to expand its manufacturing of specialized sensors and bio-sensing chips.

Industry sources say Phoenix Silicon is working with key Apple supplier Cirrus Logic to produce microelectromechanical system microphone chips after 2019, aiming to supply Apple Watch, AirPods and other Apple product lines. Cirrus Logic already supplies audio chips to Apple.

Sources also suggest that Phoenix Silicon teams with Illumina, the world's leading provider of DNA sequencing technology, to help produce chips for genetic research.

Benson Wu, Phoenix Silicon's general manager, confirmed a MEMS microphone chip project that could generate revenue for the company by the end of 2019. But he declined to provide customer details.

Phoenix Silicon draws about 45% of its revenue from wafer reclaim services and 30% to 40% from wafer thinning, Wu said, while the sensor business yields roughly 15%.

The company reported revenue of NT$1.85 billion for 2017, with net profit of NT$167 million. Revenue for the first half of 2018 rose 5% on the year to NT$984 million, and Phoenix Silicon expects a stronger second half. U.S.-based Applied Materials, the world's biggest semiconductor equipment maker, is the leading shareholder of Phoenix Silicon, controlling a 13% stake
