Chapter 983 The Lithography Machine Tape-Out Is Successful
For a while.......
Lin Mo's expression was full of excitement!
after all......
The Blood Bodhi thing...
If you get it yourself.
So......
If you step into the level of a martial arts master...
That is to have full confidence! !
"Blood Bodhi..."
After taking a deep breath.
A smile appeared on Lin Mo's face at this time.
Then, the phone was turned off.
time flies.
Three days later.
Parents are also back, after having a meal with them.
Lin Mo arranged for his own private jet.
Then, he drove and took a few old people to the plane.
When I saw this private jet of Lin Mo.
The few old people here are also one after another, shocked! !
after all......
This private jet is really shocking! !
Huge private jet, the interior is even more luxurious.
Comparable to the decoration of a five-star hotel!
When looking at this luxurious plane, the few old people here were completely shocked!
after all......
This scene is really shocking.
I feel even more confused...
To know......
This is a private jet!
They used to be...
I dare not even think about it...
after all......
This is really, too scary!
Existence far beyond their cognition......
After boarding a private jet...
A few old people are complicated in their hearts.
Soon, the private jet took off.
As for after getting off the plane, Lin Mo also arranged a nanny car for pick-up.
time flies......
A day passed.
The next day, early in the morning.
Lin Mo was woken up by the ringtone of the mobile phone.
Pick it up and take a look, it's Meng Qingzhou's call.
Looking at Meng Qingzhou's news, Lin Mo paused slightly.
Then, connect the phone.
"Hey, what's the matter?"
Listening to Lin Mo's words, Meng Qingzhou's voice sounded.
The whole person is very excited!
At this time, Meng Qingzhou couldn't help saying: "Boss! Our chip tape-out has been successful! The yield rate of shipments has reached 98%! And we have already started to try multiple exposure technology, trying to use 28nm lithography machine, and produce 7nm chips.”
"Oh? Got an idea?"
Lin Mo is a little excited!
"Now we have a direction." Meng Qingzhou said excitedly, "We still have to give Xiao Huang credit for this matter. Originally, we didn't have much clue and direction for the multiple exposure technology. As a result, Xiao Huang proposed A very interesting direction, so that we successfully made the multiple exposure technology."
Listen to what Meng Qingzhou said.
Lin Mo here, is just a nod.
"Yes, Not Bad."
Lin Mo looked calm.
"Okay, keep going, I will inform Mayor Li about the success of 28nm tape-out.
It's time for these things to be publicized. In addition, the factory construction... also needs to be carefully considered...
Your words give me a breakthrough, multiple exposure technology, and realize 7nm chip tape-out as soon as possible! "
As he spoke, Lin Mo just hung up the phone.
The look of the whole person is full of excitement! !
28nm chip, tape-out yield rate reaches 98%!
This can be said to be the first of its kind!
Most lithography machines, 28nm chips, have a yield rate of 80% or 90%, which is very awesome...
And my own lithography machine, the current yield rate can actually reach 98%!
This is not the first of its kind, is it?
The other thing is...
Multiple exposure technique.
Chip multiple exposure technology.
This technology is the core technology of most lithography machine manufacturers.
After the lithography machine enters the fourth generation, the smallest process node is 28nm.
As for the fifth-generation lithography machine, the world is currently monopolized by one company.
As for the sixth generation lithography machine.......
This thing is still in the legend.
The fourth-generation lithography machine, after the node reaches 28nm.
If you want to zoom out further, relying on a single exposure is already powerless...
Therefore, the industry has begun to use multiple exposures or etching to realize the shrinking process.
Among them, the two most critical processes are double exposure technology and self-alignment double imaging technology.
The so-called double exposure technology adopts the superposition of different graphics before and after exposure to achieve a smaller and finer process.
The advantage of this method is that it can achieve higher precision, but the disadvantage is that it increases the cost and process, and requires higher accuracy of superposition.
In contrast, the self-aligned dual imaging technique is much easier and can achieve twice the accuracy.
But this approach also has a very obvious disadvantage.
That is the design engineer, and the designed layout must conform to certain rules.
In other words...
Only designs that meet certain rules are suitable for the use of self-aligned dual imaging technology. …
It is for this reason...
All over the world, every lithography machine factory will have such a headache...
For this technology, I can only sigh...
after all......
There are two ways, each with pros and cons....
However, the fourth-generation lithography machine has indeed come to an end...
But the fifth-generation lithography machine is completely monopolized...
If you want to break the monopoly, you can only find a way to achieve a technological breakthrough.
Created...
Own extreme ultraviolet lithography machine.......
However, the difficulty inside is so easy that it can be broken through? ?
If it is really that simple, this technology will not trouble the global lithography machine market for so many years...
heart sigh...
The next thing Lin Mo did was to call Mayor Li.
After the phone was dialed, the voice of City Chief Li sounded.
"Haha! Mr. Lin, what can you do?"
"Well, Mayor Li, I'm here to inform you of something."
Lin Mo said indifferently.
"The lithography machine in my research institute has successfully taped out, and the manufactured chips have a yield rate of 98%..."
"How much...how much?!!"
At this moment, Chief Li shouted directly.
His expression was even more shocking!
I can't believe it at all!
"98%??!!"
