What Unimicron works on
Interconnect & Networking
Interconnect is the set of links that move data between chips, between boards and between racks. It includes wires on a package, cables inside a server, and the network switches and optical fibre across a data center. A processor is only as useful as the speed at which it can get data in and out.
Custom Silicon
Custom silicon means a company designs its own chips for its own products or data centers instead of buying standard parts. The chip is made by a foundry such as TSMC, but the design belongs to the customer.
