Geez. Don't Write About Things You Don't Understand
SEMI has *nothing* to do with chip sales. It is only about Semiconductor Capital Equipment sales.
Besides which, a book to bill ratio is completely meaningless: the *only* thing that matters about SEMI's book to bill is the bookings trend. Because a book to bill is a ratio, a ratio > 1 just means the number on top is bigger than the number on the bottom. So, if shipments (billings) are collapsing at a slightly faster pace than orders (bookings), then book to bill is > 1.
As it happens, demand for Semiconductor Capital Equipment *is* collapsing, and thats all that matters.
The editors should pull this piece and replace it with a comment written by somebody who at least knows something about these data. This is an embarassment.
