TDSEMIC was founded in 2011 and focuses on the production and sales of integrated circuits, operating in dual self-developed-brand and agency modes, covering wafer design and tape-out, IC packaging and test, and IC solution development and sales.
Industry-chain collaboration
A coordinated "Chengdu wafer design + Suining packaging & manufacturing" setup connects the full chain from chip design to volume delivery:
Chengdu wafer design
Takes custom IC development and packaging/test service orders, and delivers system solutions with independent intellectual property.
Suining packaging & test plant
A packaging & test foundry and alloy-wire material plant established in 2010, handling IC and discrete packaging, testing and volume delivery.
Product coverage
Packages span SOT / SOD / QFN / DFN / TO / SOP and other mainstream formats, widely used across consumer electronics, communications, power electronics and industrial control.
Compliance & responsibility
We operate with integrity and ethical sourcing, comply with product quality, environmental, health & safety and business-ethics regulations, and treat corporate social responsibility as a long-term goal to drive sustainable development of the industrial chain.
