That is the truth, the chip development in China falls behind some developed countries like America, Japan and Korea because of accumulation of technology at an early stage. Decades of barrier in developing chips, it seems hard to catch up in a skyrocketing speed for China. China is awaking in a rapidly developing time, and it has greatly changed in chips.
Take a look at this group of data, Hisilicon and UNIS are two Chinese enterprises on the list of TOP10 Fabless in 2017. Both of them quickly developed last two years and respectively promoted 21% and 9%. Relatively, both chip makers in R & D and production shows that there are position and discourse for China. But wafer fabrication is very important to make good chips in addition to research and development.
It depends on the chip developing environment in China. For example, SIMC implements 14nm technologies of wafer fabrication with a yield over 95%. Though 7nm technologies haven’t been archived, it is widespread,”The most profitable isn’t technology but mature technology.” In other words, the 14nm technologies can be adequately used to maximize profits by Chinese foundries, when Samsung and TSMC are stick to 7nm technologies they will gain more clients. After all, it isn’t sure how long will be cost by Samsung and TSMC.
