Hi all ,

What does DIE in reference to integrated circuits means ?
What are the differnt types of DIE and does an IC with with two diffferent DIE (Generations ) behave differently ??

during ic manufacturing they fabricate wafers consisting of individual chips.

a wafer contains many individual chips , which is called as 'die'.

after fabricating , each individual die is tested and cut .
then they are packaged in a plastic or some carrier.
for eg, if you see a 20pin ic , inside you will have the die connected to external ic pins through wires.

Hi ,

Does it mean that if an IC with similar packaging is manufactured using two different DIEs will have same electrical and physical characteristics.

Please Correct me if i am wrong .

Also what are the different types of DIEs ?

cannot get what you exactly mean by 'two different die'.

a wafer will have 1000s of dies .
assuming that all are going to be of same ic ,
then each die is the unbonded form of the final ic.

if you get the two ics from the same batch , then their 'main' characteristics are same.

but a given ic is guaranteed for the parameters irrespective of the batch or wafer , by the manufacturer , thro quality control.
