IC manufacturers with a name starting with 'U'

Notes:

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