Why are Sumitomo Chemical India shares up today?
The sharp surge in Sumitomo Chemical India shares comes after its Japanese parent, Sumitomo Chemical, said that its Korean subsidiary, Dongwoo Fine-Chem, has signed a joint venture agreement with Samsung Electro-Mechanics to establish a joint venture company to engage in the business of glass core substrates for advanced semiconductor packages.“In recent years, driven by the growing adoption of generative AI, expanding data centre investments, and rising demand for high-performance computing, semiconductors have been required to achieve even greater integration and lower power consumption. As a result, semiconductor package substrates are also needed to support further increases in size and density. This has led to glass core substrates garnering attention as a technology that supports next-generation semiconductor packages,” the company said in a press release.

Glass core substrates are next-generation semiconductor package substrates which are characterised by excellent rigidity, dimensional stability, low warpage and low thermal expansion, which contribute to larger package sizes, improved reliability and higher-density wiring, the company said. “In particular, AI-related semiconductors are expected to see even greater package enlargement and higher density going forward, and glass core substrates, which are a promising option well suited to these requirements, are expected to experience a full-scale market launch,” it added.
Sumitomo Chemical said that the new company to be developed as part of the joint venture is scheduled to establish a supply system by the second half of the fiscal year 2027 with a share capital of KRW 482,100 million.
