Malaysia is developing a 2,300-acre artificial island off Penang to strengthen its semiconductor industry amid rising demand for chips used in artificial intelligence infrastructure.
Known as Silicon Island, the development is being built through land reclamation south of Penang Island. The state has been a major electronics manufacturing centre for more than five decades, but limited industrial land is creating pressure for expansion.
The project aims to attract higher-value activities, including semiconductor design and advanced packaging, beyond traditional chip assembly and testing.
It is projected to create around 220,000 jobs by 2050. A Deloitte study cited by the developers estimates that it could contribute RM1.1 trillion to Malaysia’s economic output cumulatively by then and attract about RM74.7 billion in investment. These figures are projections, not realised gains.
A proposed 720-acre Green Tech Park will focus on semiconductor design, advanced packaging and automated testing. According to the developers, its first phase is planned to run entirely on renewable energy.
Gamuda holds a 70 % stake in Silicon Island Development, the project’s developer, while the Penang state government owns the remaining 30 per cent. The state government will retain ownership of the reclaimed land.
Industrial operations are expected to begin in early 2028. Full reclamation could take another three to four years, while construction across the wider site may continue for up to 15 years.
The project’s economic impact will depend on its ability to attract manufacturers and convert planned investment into operational facilities. For Malaysia, Silicon Island represents an effort to expand Penang’s established semiconductor base as competition for global chip investment intensifies.
