TSMC: 7nm Now Biggest Share of Revenue
 

As process node technology gets ever more complex, it costs big dollars to develop and then building chips on the process is also a very costly process. The big foundries often have many process nodes running in parallel across a wide range of price brackets in order to both diversify the revenue streams but also offer multiple competitive options for the market.
