Sun's semi-master wafer recycling, wafer thinning and foundry services for micro-electromechanical (MEMS) mid-range processes. Terminal products are mainly used in semiconductor wafer foundries, industrial and automotive power electronics, and bio-detection related. The company's main customers are semiconductor foundries with global market share of about 60%, such as TSMC and power semiconductor maker Infineon (Infineon).
Last year began to warm up demand for power semiconductors for industrial use, automotive use, etc., driving demand for power semiconductor separation devices such as MOSFETs (metal oxide semiconductor field-effect transistors). Demand has soared. Demand has soared. Revenue for the first half of May was 186 million yuan. , Monthly increase of 11.32%, annual increase of 15.68%, single-month revenue hit a record high.
Looking at the revenue growth of this year's semi-income semi-annual, compared with the same period in 2017, except that the revenue was the second highest in March of last year, it was worse in March this year and the rest of the month has grown compared to 2017. The main reason is that The demand for MOSFET thinning foundry products has increased. As a result, the thinning capacity of MOSFETs invested by Shengyang last year and a half last year has been gradually released since May, and its revenue contribution has increased significantly.
