People should understand that when you say you 'manufacture smartphone', it doesn't mean just producing it. There are so many steps before it and manufacturing is the last step. Most of the designing stuffs (which is the main thing) happens in US. Menial jobs are outsourced to India, China and production is sent to Taiwan (most of the times). Hope this answers kiddo's post. 

Another point to note is that Nepal produces the more no. of Electronics, Computer and Civil Engineers than any other branches. So obviously Electronics and Computer Engineers are in maximum number. If we see their careers, they either enter into Software jobs or NTC or very few big companies. My point is they never get to work on real semiconductor jobs while in Nepal. So if we can atleast start some sort of companies or invite some of them, we can train our manpower nicely. Then smartphone won't be far away, atleast designing them. Fabrication and production should be outsourced because that is more than a million dollar investement in itself.
