Sai Microelectronics: the production capacity of MEMS process and wafer foundry has been tight, and the order waiting time is long.

On July 13, Saiwei Electronics accepted a survey of institutions, according to which it said that the company will actively grasp the market demand and strive to become a well-known semiconductor enterprise group based on local and international development.

According to Sai Microelectronics, in recent years, facing the era of the Internet of everything and artificial intelligence, Sai Microelectronics has formed a business pattern with semiconductors as the core, and MEMS and GaN have become strategic businesses at different stages of development and focusing on development. At the same time, the company carries out investment layout around related industries and serves the main business. Based on the advanced 8-inch production capacity of the industry's top expert engineers, mature processes and the continuous expansion of the MEMS field.

Sai Wei Electronics actively grasps the market demand and provides global customers with high-standard MEMS process development and wafer manufacturing services; at the same time, based on the industry's top technical team and excellent product performance, actively and rapidly layout GaN industry chain, and provide GaN (gallium nitride) epitaxial materials, GaN devices and supporting application solutions for new power supply, intelligent home appliances, communication equipment, data center and other fields. Sai Microelectronics implements the long-term development strategy and is committed to becoming a well-known semiconductor technology enterprise group based on local and international development.

Sai Microelectronics said: "since the completion of the merger and acquisition, the company has actively supported the upgrading of the Swedish production line and continued production expansion. The Swedish production line made a capital investment of more than 300 million yuan from 2017 to 2020. in September 2020, the original 6-inch production line (FAB1) was upgraded to an 8-inch production line, and the original 8-inch production line (FAB2) has also completed production expansion, increasing the total MEMS wafer production capacity to the level of 7000 wafers per month. The production capacity has continued to increase by 30% from the end of 2019, and capital investment is still continuing due to the needs of key customers.

According to the introduction, the comprehensive gross profit margin of the company's Swedish production line MEMES business in 2020 is close to 50%, and the net profit rate is close to 30%, which is expected to remain at a high level now and in the future. Because Beijing MEMS production line is a new production line, there is a great pressure of depreciation and amortization, and it is expected that wafer manufacturing business will account for a large proportion of the income structure, and the product structure of income will also be different from that of Sweden, so the gross profit margin and net profit margin of Beijing FAB3 production line at the initial stage of operation will be lower than that of Sweden production line. As the volume grows, the overall gross margin of the company's MEMS business is expected to decline (but can still maintain the normal level of the chip contract manufacturing industry).

The company also said that in recent years, the company's MEMS process development and wafer foundry production capacity has been relatively tight, and the order waiting time is longer. From the calculation results of the wafer unit price, the increase in the wafer price in recent years is sustained and rapid. The average selling price of the company's MEMS wafers from 2017 to 2020 is about $1700 / chip, $1800 / chip, $2200 / chip and $2700 / chip, respectively. Among them, the unit price of process development wafers is much higher than that of wafer manufacturing, with an average price of about US $5500 per piece in 2020, and some products can exceed US $10, 000 per piece.

According to the product category, the average selling price of consumer electronics MEMS wafers is lower, while that of biomedical MEMS wafers is higher, but there are different distributions among different types of wafers. Like the Swedish production line, the Wafer price of the Beijing production line varies greatly from category to category. At the same time, the price of the product in the wafer manufacturing (mass production) stage is generally lower than that in the process development (pilot) stage.
