if you wanna to study in sg, ntu is better than nus
nus is much better in the microe process, has many professors, but few in ic design. i think hch is only one who specialize in ic design. u can know this by the module offered. only a few modules regarding ic design
for ntu, ic design is a department, not like nus(ic design is just one division of microe)

but i suggest u to study the pdh in us. but it takes at least 5 yrs n hard to graduate. but return is high
