Recently DigiTimes revealed, TSMC has begun mass production of 7nm N7 + chips. The new chip has 10% better performance compared to the current 7nm. The company is said to have started mass production of 7nm chips and will produce 150% more this year.
The new chip series uses ultraviolet photolithography (EUV) technology to fundamentally design chips and place components on more precise silicon wafers. The transistor density of N7 + is also 20% higher than N7 and save 15% more electricity.
The 7nm process also means TSMC can put more transistors on the same space of the chipset. As a result, SoC is not only faster but also consumes less power.
Thus, the technology community can expect the emergence of 7nm N7 + smartphones in this year with outstanding performance and better battery saving. Probably 2019 will be the hinge year of the 7nm chip before we move on to further processes.
If you remember, the early iPhone launched in 2007 using 45nm process chips, it can be seen just how much the chip industry has evolved over the past 12-13 years.
TSMC is said to have started planning mass production of 5nm chips by 2020. The company has now shipped the equipment needed to produce 5nm chips at a new facility called Fab 18. The 5nm chip is expected to work conversion rate is 15% higher than 7nm.
Former Intel co-founder Gordon Moore once made a remark in 1965 that the number of transistors per square inch inside a circuit board will double every year. Since then the technology community has believed that Moore's law will only die when we reach the 7nm process.
And indeed, chip makers have done that and even want to break the record as they progress to lower processes like 5nm and the future will be 3nm. Recently, there are reports that TSMC is preparing to open Fab 18 facility to produce 3nm chips in the next few years.
So far most industry experts believe that 5nm will be the limit and mark the end of Moore's law.
But this does not mean the chip will not continue to improve performance after the limit has been reached. Just as the process is getting smaller, the process of performance improvement will take longer, no longer a year, but can last up to 2 years or more.
TSMC is currently one of the largest chip manufacturers in the world. The company specializes in producing multiple chips for partners such as Apple A-series for Apple, Kirin for Huawei and Qualcomm's Snapdragon chip line.
