I am sorry if I touched a raw nerve somewhere. By backend do you mean A&T? If so I cannot list more than SPEL Semi in Chennai which is doing some volume packaging. So there are no 80-90 units in India. And if you meant design services as backend, IC design engineer do not qualify as a process engg in a wafer fab. I say that because I worked for 17 years as a fab process engg. I commented with a full and thorough understanding!
I do agree about the poor infrastructure, but when it comes to lack of skilled manpower, I disagree with you. If you look around you will find most of the backend operations for semiconductor cos are outsourced to India. You have atleast 80-90 semiconductor start ups with projects for the Top notch Semicons. This is just a start. Try not be a pessimist without knowing the actual picture around you.
With a poor infrastructure, lack of skilled manpower and the cream of engineering manpower with a lack of interest in anything other than software and financial services, India has a mountain to climb. If a cement manufacturer is able to see a future with all the odds stacked against such a venture, I can only smell a scam of humongous proportions!
Jaypee is the money and the Indian company with a strategic interest (a bit like Formosa Plastic in Taiwan).
Tower's contract to build and operate the fab would be with Jaypee, if the bid is successful.
