content: Hello everyone! I have several chips with logos that I can't identify. Could someone please identify the manufacturer of these chips based on the logos?Logo 07 is very similar to National Semiconductor, but it's not it.According to some websites Logo 06 should be Seiko Epson, but I haven't been able to confirm this anywhere. Neither on the Epson website nor on any Datasheet.Thanks,

content: #3 -- ADD Microtech Corp.#4 -- Ericsson.#6 -- Seiko-Epson, and formerly it was the logo of SMOS Systems.#8 -- Siliconix.Why don't you make it easy for us and show us the whole IC? Or is this a test?

Not sure it's them or one of the fifteen million small Chinese outfits, who like to make very close copies of well known ones if not outright clones, hence #7 which is an obvious Nat Semi "copy".Would be nice if the image quality was a bit better, too

content: KHIC is weird, apparently it's Macronix's "low grade" brand just like Micron's SpecTek (and the logo amusingly looks like Micron's old one.)

content: Quote from: fzabkar on July 01, 2025, 11:30:00 pmI only had photos of the logotypes. But I took photos of the entire IC, where it might be relevant, from the bottom or the side.I apologize for any unnecessary complications I may have caused.

content: I have a few more questions about the identified logotypes:#8 Siliconix - everything is clear#6 Seiko Epson - some websites mention it, but I haven't been able to confirm it anywhere. Is there a datasheet or document that would confirm it? Epson simply uses the EPSON inscription everywhere instead of the logo.#4 Ericsson - that would be a strange Ericsson. Ericsson would be rotated 90°#3 ADD Microtech Corp. - I couldn't find anything about this company's logo anywhere. Could I find a document to confirm the logo, please?#2 KHIC - after some help here on the forum, I found the elnec.com website. But from there it refers to the aforementioned Macronix. So what about the KHIC brand, please?#7 Made in Japan - it won't be some Chinese minibrand. But it wasn't visible in the first photo, I apologize for that.

content: With your permission, I would like to ask for the identification of two other logos. In both cases, these are N-E-MOS transistors.

content: That would be"Jiangsu Dongguang Micro-electronics"and"Wuxi China Resources Huajing Microelectronics", respectively.Incidentally here's a useful page with tons of Chinese semiconductor company logos:https://www.csemigroup.com/
