IC manufacturers with a name starting with 'U'

Notes:

• Beware that a company may be listed under it's abbreviation ('IBM') but alsounder it's full name ('International Business Machines') so when you wantto make sure, check both places.
• These listings usually cover about 99.9% of all chip manufacturersso it will be very appreciated by me and currently about 250,000 ofyour colleagues (monthly) all over the world when you would emailme about anything that should be changed or added.
• For foundries see also the foundry andchip making pages.
