Silicon Investigations I.C. manufacturer logos reference.
This is a partial list of semiconductor integrated circuit manufacturer's
logos, as pictured on the top of the chip packages. The logos may differ
from the web site logos and may change periodically, particularly with shrinking
package sizes. Where there are multiple logos used, we try to list
all of them here. Some variants are used as the foundry marks on the
actual integrated circuit die. This information can be very useful
when searching for the manufacturer of an unknown chip, particularly in the
case of counterfeit chips from China and India, as the logos my look authentic,
but are actually copies.
The list is updated as time permits, so newer
manufacturers may not be listed yet. The semiconductor industry
is constantly changing as manufacturers merge, spin off product lines
to new companies, and, unfortunately, cease operations. If you
don't see a logo listed, please send us an email with a jpg or
gif attachment of the logo, and we will
research it and add it to this page as time permits.
