Military Industry of Great Powers: Build the Strongest Flanker

AMD knows what they need, and Zhongxun, no, it is Teacher Xiao Zhao who knows what he needs.

Of course, General Muhu also knows what he needs?

On New Year's Day, General Muhu came to No. 102.

"Congratulations, General Manager Zhao, the 193nm lithography machine has made us proud!"

Zhao Guoqing said: "I am also relieved, finally I didn't spend money in vain!"

Without taking a sip of tea, Mr. Mu went straight to the point and said, "Mr. Zhao, now that the lithography machine has been upgraded to a generation, this chip...?"

Zhao Guoqing understood instantly that Mr. Mu was thinking about the radar he was thinking about.

"45 nanometers, but it will take some time before it is suitable for military use!"

There is a big difference between military chips and civilian chips. The most direct difference is that military chips require high reliability and can still work normally in strong electromagnetic environments, ultra-low and high temperatures.

You must know that the radar emits electromagnetic waves when it is working, and also receives interference from the electromagnetic waves emitted by the other party.

Electromagnetic waves are energy, which will be converted into current when encountering a circuit. Strong pulsed electromagnetic waves will be converted into current pulses. The voltage of ordinary civilian chip designs is generally within 5V, and a current pulse can even be directly eliminated.

Although Teacher Xiao Zhao is also an expert in this area and has many ways to deal with it, he is worried that it is too abrupt to just take it out like this.

Of course, the biggest reason is that this matter is not that urgent.

The two existing phased array radars are already outstanding enough, and can even compete with American radars.

"General Master Zhao, are there any difficulties?"

Teacher Xiao Zhao nodded and said: "A lot of basic research is still needed, and the cost of tape-out is not cheap. How much money can Mr. Mu apply for?"

"..." When it came to money, Mr. Mu said hesitantly: "You should be able to apply for 200 million!"

Zhao Guoqing asked: "US dollars?"

Mr. Mu shook his head and said: "RMB!"

Teacher Xiao Zhao stopped talking...

Mr. Mu is a bit joking. Even if there is no need for basic research, Teacher Xiao Zhao will pour out all the inventory in his belly. This little money is not even enough!

Mr. Mu said: "Mr. Zhao, isn't two hundred million enough?"

"Mr. Mu, apart from other things, the higher the process, the higher the mask requirements for chip production. A one-micron mask is directly exposed on the glass, and the cost is only 100,000 yuan. At 45 nanometers, 193 The penetration of nano laser is different from that of 246 nanometer. It requires depositing a metal layer on the glass, then applying the exposure layer and etching..."

Mu Hu was confused when he heard this, and hurriedly said: "General Master Zhao, I don't understand if it goes too deep. Please tell me clearly!"

"..." Zhao Guoqing said helplessly: "A 1-micron chip mask only costs 100,000 yuan, and one million yuan can be used for tape-out. The cost of a 45-nanometer mask is 500,000 US dollars, and a tape-out requires at least 60 yuan. The mask version requires at least 30 million US dollars to tape out..."

"Thirty million dollars?"

Zhao Guoqing nodded. This is only 45 nanometers. If it is 14 nanometers, one taping will cost 100 million. One taping of 7 nanometer process will cost 300 million. By the way, it is US dollars.

Either it can only use civilian money to support the military, or if there is no civilian money for continuous blood transfusion, no country has the financial resources to develop high-performance military chips!

Zhao Guoqing nodded and said: "This is just a tape-out. If you are lucky, it will pass once. If you are not lucky, it will need to be modified. Just manufacturing this piece will take at least three tape-outs... And the demand for military chips is not high, at most. Hundreds of pieces to the top!”

"So much? Is 200 million yuan enough for one tape-out?" Mr. Mu shook his head, in disbelief, feeling that a radar chip could wipe out all the air force's assets.

Well, there’s nothing I can say!

"Mr. Zhao, this is the cost price. Institute 102 has not made a penny. If it is provided to the military alone, it will look like this, but if it can be sold outside, that is another matter!"

Although there are no active phased array radars shipped in the international market, or even passive phased arrays, the export price of the American ag66 has reached 6 million U.S. dollars, and the active phased array starts at least 20 million U.S. dollars. Bar!

Of course the state will definitely not sell it!

Sure enough, Mr. Mu shook his head and said: "Not to mention the active phased array, the exit of the passive phased array is also an interview!"

Pakistan has been begging for it for three or four years, but the passive phased array type 1 radar has not yet received export approval.

The second type is equipped with a 500-nanometer process brain, which can effectively resist electromagnetic interference and has more powerful performance, but its ability to detect invisible objects is basically non-existent.

There's nothing we can do about it.

The power of radar lies in the processing of echo signals.

The power of phased array radar is that it can concentrate the electromagnetic wave beam in one direction and increase the electromagnetic wave energy in the scanning direction.

Just like an ordinary Doppler radar is like a torch, the light is scattered in all directions and the distance it can illuminate is very short. Most of them are within 70 or 80 kilometers, and most can only see 30 or 40 kilometers.

Regardless of whether it is active or passive, phased array radar emits electromagnetic waves the same way. It is like a spotlight, concentrating energy on a certain place and naturally seeing farther. Most of them have a detection range of more than 200 kilometers.

Active phased array radar and passive phased array radar focus on the processing of echo signals.

The active phased array array antenna can receive echo signals more clearly, and a powerful processor is the basis for processing large amounts of echo data.

The power of the active phased array lies in its powerful calculations, which can use calculations to determine whether the tiny signals that were directly filtered out before are targets.

By calculating the echo characteristic values, it is possible to identify what kind of aircraft the target is.

Even the tiny targets that were directly filtered out on the radar screen in the past can be determined by calculating the altitude, speed, and echo characteristic values ​​to determine whether the tiny target is a sparrow or a stealth aircraft...

It can be said that the mature active phased array radar, combined with the meter wave array antenna, can make the stealth performance of the F22 and F35 a joke, and of course the Nighthawk is no exception.

Powerful is really powerful!

"General Master Zhao, is there really no other way?"

Zhao Guoqing said: "Mr. Mu, military use actually does not require a very high process. 130 nanometers is enough, and the tape-out is about 10 million US dollars. Also, the computing chips of array radars are not only used in fighter-borne radars, but also in shore radars." Both base array radar and vehicle-mounted array radar can be used, and the air finger can be jointly funded by the Army and the Air Defense Force Equipment Department!"

"What a great idea!" Mr. Mu's eyes lit up. The air force's budget plus the air defense force's budget could be combined, wouldn't it be enough?

“What kind of performance can be achieved, and how far can the active phased array detect?”

"..." Zhao Guoqing said helplessly: "Mr. Mu, the detection distances of passive phased arrays and active phased arrays are about the same. The only difference is..."

How to explain it?
