you officially knew nothing
designing the chip is the hard part, designing a new node is the hard part , building a fab is the easy part
Who says this? On what basis do you claim this? Architecture is hard but even ten it is simulated on computers and hence made easier. But making the actual chip is hard because it involves shaping the silicon wafers to the precision of at least 100nm (for 1um chip) to 1nm (for 14nm chip). There is where the difficulty arises. The chemical reaction of silicon fabrication to be controlled to such precision is where difficulty arises.
people build their chips in TSMC or Samsung because they have the production capacity and invested in the cutting edge node .
today every body can build a 32nm node but for military nobody use lower than 90nm because of reliability .
People make chips in TSMC because they don't have the technology to make them. Otherwise, it hardly makes sense to manufacture one's military items in another country.
None can make 32nm excepting USA, China and USA vassals (like Taiwan, S.Korea). It is not a choice to not make the items. It is capability deficit or lack of technology.
and if you guys willing to dish some money you easily can buy devices to build your own 22nm FAB , you just don't want to spend that money as your needs are not that high that economically made the decision justifiable
We are more than willing to dish out money, even $20 billion for plant to manufacture the wafers. But none sells. India couldn't even get USA (IBM) to give 180nm technology and India had to upgrade it indigenously with Israeli consultancy.
Each chip of intel i5 costs $100 and one chip of Snapdragon processor costs $30-40 dollar for middle level chipset. Considering that India spends several tens of billion dollars each year, it makes economic sense to have at least 22nm technology. But none sells
wrong , older generation lithography devices can be bought easily
Who sells that? Do you know of anyone who will sell even 1um technology? The machines which is used for lithography is sold by NATO country in international market. Other countries which have it are China, India and Russia. No other country has the ability to make lithography machines even of 1um.
the lithography device is not important , the science to design the chip is the key point . its take china 20 years to design an architecture good enough to be used in competitive products
The lithography is the most important science. China took that many years to et the lithography, not design. Design is just about making logic gates design and is mathematics. It is done even by simulation as mathematics can be algorithmised. The chemical reaction of lithography is the key
you can only talk about poor accuracy of Iranian missile when you managed to hit a boat with your ballistic missiles or point camera to a tent and say we fired a longer than 2000km range missile and it gonna hot that tent and then hit that tent . till India show that capabilities let not talk about precision of Iranian missiles
Ballistic missile hitting a boat? Where? This is a new thing as ballistic missile can't hit moving target. India has CEP of 10metre for its Agni-5 missile. Iran can make missiles like Styx missile of 1960-70 which were used as anti-ship missile using simple radars or 1960-70 type ballistic missiles with CEP of 500m to 1km but making a precision missile using semiconductor is another thing.
