I have several different ICs laying around with the same manufacturer icon marked on top of the ICs. I searched on several IC-logo web sites, but so far, I couldn't identify the manufacturer.

Do you know who is the manufacturer of this IC?IC

Thank you !

Most probably manufactured by Beijing Estek Electronics, here's the datasheet.

Next time, if you look for component manufacturer, go to site like datasheetarchive.com, and put component name in the search. It will list all datasheets available for the component, and if there's no logo displayed which you will match, you can guess from supplier's name, or just open PDFs until you find document with logo needed.
