An iPhone order brings up the advanced packaging market

These 5 companies grab the spot and TSMC’s advanced packaging team, which also brings opportunities for PCB industry players

In the past four years, TSMC has used advanced packaging to compete for business opportunities that are far more than just iPhone processors. For example, AMD (Super Micro), which has soaring stock prices in 2020, uses advanced packaging technology for the latest version of its chips. Open AMD’s latest processor, you can see the core chip made of 7nm, the peripheral unit is made of 14nm, and then use advanced packaging to form a chip; through this method, AMD only needs to increase the core on the chip The number of chips can quickly improve the performance of the chips, and the market share is therefore continuously increasing.

In addition, the supercomputer chip developed by Fujitsu, the Tesla graphics chip of Nvidia, the next-generation AI chip of Broadcom, and the FPGA chip of Xilinx are all customers of TSMC’s advanced packaging.

TSMC’s latest SoIC is even more powerful. According to TSMC’s public information, this technology can arbitrarily combine chips of various processes. In addition to memory, it can even directly package the sensors together in the same chip. In the future, when you take a picture, from receiving and storing the image to recognizing the image, things that can only be done by a computer system in the past may be done with a single chip. According to the information released by TSMC, the circuit density of TSMC’s SoIC+ packaging technology will be 1,000 times that of 2.5D wafer packaging.

According to industry sources, Apple will use more advanced packaging services in the future. Apple’s M1 chip will be packaged in traditional BGA in 2020 and will be switched to wafer-level packaging in 2021; therefore, although TSMC now has 4 advanced packaging plants, However, it is actively building a new factory in Miaoli. With the rise of advanced packaging, a new industry chain has emerged. The following companies will be members of TSMC’s advanced packaging team.

Fine Materials Receives TSMC’s Wafer Level Test Business

Player 1: Fine materials. The Jingcai team has been researching advanced packaging for many years. In the past, one of the main businesses of Jingcai was to use wafer-level packaging to make image sensors and logic ICs into a single IC. However, starting from the second half of 2020, Fine Materials will play the role of TSMC’s wafer-level test plant. The original image sensing advanced packaging business will gradually shrink. It is reported from the outside that TSMC will conduct wafer-level testing with lower gross profit. The business is handed over to Jingcai, and the third party transfers the equipment to Jingcai, who is responsible for operation and management.

“Apple wants to reduce costs, and TSMC wants to increase gross margins, making fine materials the best choice.” According to industry sources, fine materials have recently fluctuated because the market has different views on whether there will be new orders for fine materials in 2021. In the first 11 months of 2020, Jingcai’s revenue has reached a record high in the 17 years since its establishment.

Player 2: China Southern Power. The industrial changes brought about by advanced packaging not only affect the packaging and testing industry, but also have an important impact on PCB (printed circuit board) factories. Nandian is the best representative.

An packaging and testing industry observed that when TSMC first introduced advanced packaging, because this technology can directly integrate several chips distributed on the PCB board into one chip, “Nandian has an entire PCB production line. Up!”

However, advanced packaging is also an opportunity for PCB manufacturers, because in advanced packaging technology, the chip must be placed on a high-precision carrier board to connect the chip to the physical circuit. “If the PCB circuit used to be a flat road, the carrier board is a three-dimensional elevated road.” According to industry analysts, the manufacturing requirements of the carrier board are getting closer and closer to the semiconductor. On the most sophisticated carrier board, the circuit width is only a few microns. , On a carrier board the size of a nail, it must be able to hold thousands of circuits.

Therefore, one of the evidences of the popularity of advanced packaging is that ABF carrier boards are in short supply. This material meets the current needs for high-frequency communication and high-speed computing, and can only undertake the task of connecting expensive chips. “The high-end ABF carrier board has a yield rate of almost zero.” According to industry sources, TSMC and Licheng are closely watching the production progress of the carrier board factory. An executive of a packaging and testing plant said: “The supply of carrier boards now directly affects the production capacity of advanced packaging.”

Nandian and Xinxing carrier boards are the big winners under the tide of stock-out

ABF is out of stock, and Nandian’s profitability is also taking off. In the third quarter of 2019, the gross profit margin of Nandian was only 3%, but in the third quarter of 2020, it rose to 14%. During the law meeting, Nandian also said that in the past, Japan had more advantages in carrier boards, but now the ABF carrier board industry chain is shifting. Taiwan has the world’s largest market share in wafer manufacturing and packaging. Naturally, it has an advantage.

Three-quarters of Nandian’s 2020 capital expenditure will be used for ABF and other carrier boards. By the end of 2020, Nandian Kunshan Plant will complete the expansion of the ABF production line. In addition, the increase in system-in-package (SiP) application levels, such as AirPods wireless headsets, and 5G-driven antenna module packaging requirements, also increase the demand for BT carrier boards.

Player 3: Xinxing. Xinxing is the world’s largest supplier of ABF carrier boards. A few years ago, the industry had different views on the development of ABF substrates. The production of such substrates not only requires a lot of investment, but also has certain difficulties in technology. However, Xinxing actively expanded ABF production capacity at the request of its chairman Zeng Zizhang, so it became this wave of shortages. Victor in the tide.

Now Xinxing has long been an important strategic partner of Intel and TSMC. Large manufacturers such as Intel will cooperate with suppliers such as Xinxing to produce. Special carrier boards can only be used exclusively for their products. When production capacity is tight, this approach can ensure supply. The importance of carrier board manufacturers can be seen.

Player 4: Hongsu. Taiwan’s development in advanced packaging has also given local equipment and material plants new development opportunities. In the past, the equipment and materials in the semiconductor manufacturing process required higher requirements than the general electronic manufacturing process, and most of them were foreign companies. However, this time when TSMC and other companies develop advanced packaging, they will also give local manufacturers opportunities in order to accelerate the development of the R&D process. Since TSMC’s process research and development mostly adopts the A and B two sets of competition, finding a manufacturer willing to cooperate fully is also very helpful to the research and development schedule.

Player 5: Changxing Chemical. Since materials account for more than 30% of the cost of advanced packaging, and the trade war has increased the demand for local supply in the semiconductor industry chain, TSMC intends to strengthen cooperation with Taiwan’s local specialty chemical manufacturers. For many years, Changxing Chemical has important materials such as photoresist for PCB. It has also developed Mold Under Fill, a material for 3D IC packaging. In the past, this market has always been dominated by American and Japanese manufacturers. There are only a handful of manufacturers that can provide them. However, Changxing has developed high-fluidity packaging materials and has entered TSMC packaging. supply chain.
