China’s first listed IC-design company became an IDM: the unusual path of Silan Microelectronics
Hangzhou Silan Electronics was established in September 1997 and evolved into Hangzhou Silan Microelectronics.
The company began with chip design but chose to add its own manufacturing capacity, creating an integrated-device-manufacturer model unusual among many Chinese fabless start-ups.
What followed was not a straight expansion into every adjacent market. Silan Microelectronics moved through specific technical and commercial turning points that gradually changed what customers expected from it.
The first internal fab changed Silan from designer to manufacturer
Silan established a manufacturing subsidiary in 2001, beginning the integration of design and wafer production.
In semiconductor and electronics markets, this kind of capability compounds over time. Manufacturing know-how, yields, supplier relationships and process experience are difficult to recreate quickly, so each generation can strengthen the next.
The 2003 Shanghai listing broke new ground for a Chinese IC designer
Silan became the first integrated-circuit chip-design enterprise listed on a mainland Chinese stock exchange.
For Silan Microelectronics, access to public markets was more than a branding milestone. It increased financial transparency and created another route to fund expansion, acquisitions or long-term product development.
Consumer and power products broadened the catalogue
The company developed chips for audio, appliances, motor control, LED lighting and other high-volume applications.
In semiconductor and electronics markets, this kind of capability compounds over time. Manufacturing know-how, yields, supplier relationships and process experience are difficult to recreate quickly, so each generation can strengthen the next.
Larger wafers moved the IDM model up the manufacturing curve
Silan expanded from smaller wafer lines towards 8-inch and 12-inch production while adding compound-semiconductor capacity.
In semiconductor and electronics markets, this kind of capability compounds over time. Manufacturing know-how, yields, supplier relationships and process experience are difficult to recreate quickly, so each generation can strengthen the next.
Electric vehicles turned power devices into a strategic growth market
Silan increased investment in IGBTs, power modules and other components used in vehicle and industrial energy systems.
This was an important turning point because it expanded what Silan Microelectronics could offer or the markets it could address. The effect becomes clearer when viewed as part of the longer sequence of changes that followed.
Why Silan chose fabs when many designers were giving them up
As of 18 September 2026, silan now integrates semiconductor design, wafer manufacturing and packaging across analogue, power and mixed-signal products.
For readers following the brand today, the history explains why newer announcements often connect back to technology or business decisions made much earlier.
