On May 27, the A-share market saw a surge in sentiment in the storage sector due to the strong performance of overnight U.S. storage giants, with semiconductor packaging and testing and post-processing service-related concepts becoming active. Taking TJ as an example, as of the noon close, the company's stock closed at 14.27 yuan per share, up 7.54%; at one point during the trading session, it hit the daily limit, rising 1.33 yuan from the previous trading day's closing price, with a total market value of 30.537 billion yuan. According to the World Semiconductor Trade Statistics (WSTS) forecast, the global semiconductor market size is expected to further grow to $975 billion by 2026, with memory and logic chips remaining among the fastest-growing core areas. Industry insiders believe that this round of semiconductor recovery differs from previous consumer electronics cycles, as it is driven more by long-term demand changes brought about by AI computing infrastructure construction. Against this backdrop, the importance of advanced packaging and post-processing service segments is being reassessed by the market. In 2009, TJ established a joint venture, Haita Semiconductor, with SK Hynix through a major asset restructuring, with TJ holding 55% and SK Hynix holding 45%. As the world's second-largest DRAM manufacturer, SK Hynix occupies an important position in the global storage chip industry chain, primarily producing DRAM, NAND Flash, and CIS products. Haita Semiconductor serves as the core entity of TJ's semiconductor business, focusing on post-processing services for storage chips, mainly engaging in IC chip packaging, packaging testing, module assembly, and testing. Since the cooperation began, the two parties have signed four phases of post-processing service contracts consecutively. On the evening of June 18, 2025, TJ announced that Haita Semiconductor plans to sign the "Fourth Phase Post-Processing Service Contract" with SK Hynix, with a contract period from July 1, 2025, to June 30, 2030, extending their cooperative relationship for another five years. According to the announcement, the cooperation will continue under the "all costs + agreed returns" model, which means that on the basis of covering all costs, an agreed return of 10% of the total investment amount will be charged annually, with additional rewards based on cost control performance. This model helps enhance business stability and cash flow certainty, reflecting the international storage leader's recognition of Haita Semiconductor's long-term delivery capability and post-processing service system. According to the 2025 annual report, TJ's semiconductor business achieved operating revenue of 4.65 billion yuan, accounting for over 15% of the company's total revenue, with Haita Semiconductor achieving operating revenue of 3.939 billion yuan, making it one of the company's important business segments. Meanwhile, Haita Semiconductor also maintains a high level of production capacity. In 2025, the company's maximum packaging and packaging testing output reached 2.696 billion Gb capacity/month and 3.042 billion Gb capacity/month, respectively, representing year-on-year increases of 16.62% and 34.60% in maximum monthly output From the perspective of industry development trends, as the demand for high-performance storage increases and the prosperity of the storage industry chain shows signs of recovery, the focus of the semiconductor industry chain is gradually shifting from single price fluctuations to dimensions such as capacity collaboration, delivery stability, and long-term customer relationships. Post-processing service companies with stable customer cooperation relationships and a foundation of scalable capacity are gradually increasing in importance within the industry chain ### Related Stocks - [600667.CN](https://longbridge.com/en/quote/600667.CN.md) ## Related News & Research - [4 undervalued semiconductor stocks investors can buy now](https://longbridge.com/en/news/290338575.md) - [Cross-Border Capital Navigates Hong Kong's Diverging ETF and REIT Landscape](https://longbridge.com/en/news/290538803.md) - [The best semiconductor ETF to buy with $1,000 right now](https://longbridge.com/en/news/290332243.md) - [REG - Janus Henderson NAV - Monthly Factsheet as at 31 May 2026](https://longbridge.com/en/news/290563693.md) - [Shurgard signs deal to buy freehold plot for self-storage project in Dusseldorf for EUR 16.3 million](https://longbridge.com/en/news/290438989.md)
