this should have read -
'IMO It needs their expertise when it is set to the physical silicon, the substratum as you say, on which it resides because the technology pings naturally occurring defects which are introduced in the semiconductor fabrication process. . . and look at the many complex ways there are out there to just find and delimite the defects; plus they do it initially at the fab plat to structure around them - this would be the opportune time to set up the signiture IMO.''
