7nm EUV 这回还是-10%功耗+提密度 性能么既然没说那大家都知道别指望啥惊喜了hoho 不过重申了生产周期会变短
关键是这回只说了"A few customers ....in their 2019 products" 明年基本上还是7而不是7+
N7+ is in risk production now. Since the N7+ has 15% to 20% better density and more than 10% lower power consumption, we are working with many customers for their second wave product designs in N7+. Although the number of tape-outs today account for a small portion of the total 7-nanometer tape-outs, we expect the activity to pick up at a rapid pace in 2020 and beyond. Because the N7+ is using a few layers of EUV photolithography to have better cycle time and patent control, we have made steady progress on EUV technology development towards high-volume production. Tool availability, EUV power, productivity, defect reduction, mask improvement, material and process optimization are all on schedule. A few customers have already made plans to adopt our N7+ in their 2019 products.
We're using the EUV, we have a shorter cycle time and I just say that it's kind of
better pattern control, so that means your critical dimension has been tightly controlled that help the performance also.
Next year is still 7-nanometer because 7 plus, we're working with customers and some of the customer moving a little bit faster, some of them -- and for those customers already in the 7-nanometer, they are planning on the second wave products in the 7 plus. Okay. So next year, I can say most of them are still in 7. But then activity will start to rapidly grow in the second half and then 2020 that will be even grow faster.

If I can forecast well, I mean, that 1 tapeout, especially for some of the application, it takes about 1 year to -- for ramp-up. So 7+ will be increasing, but the revenue I would expect 2020, '21 start to see the big number. But not 2019, not the first half of 2020.
