Kathy hat Dr. Neuhaus eine mail mit Fragen zum wafer level packaging Verfahren einer Japanischen Firma: http://ragingbull.lycos.com/mboard/boards.cgi?board=NPCT&rea… From Kathy: I sent an email to Dr. Neuhaus and Dr. Wernle asking what they could tell me about the new wafer level packaging that was announced by a Japanese company recently and I have received a response from Dr. Neuhaus: Subj: RE: New wafer level packaging technology Date: 10/22/01 10:35:39 AM Eastern Daylight Time From: herb@nanopierce.com (Dr. Herbert J. Neuhaus) Reply-to: herb@nanopierce.com To: KKnightmcc@aol.com CC: michael@nanopierce.com (Michael E Wernle) Hi Kathy: There are literally thousands of variations of flip-chip packaging in existence. Don`t let the alphabet soup confuse you. The site you sent refers to a type of flip chip where the underfill is applied to the wafer. This usually called (as it is here) wafer level packaging. Other than that it pretty much standard flip chip. Remember that we do not compete with flip chip but instead depend on the broad acceptance of flip chip by the industry. We offer a type of flip chip that is extremely simple and low cost. Ours is, therefore, particularly attractive to low-cost, consumable electronic applications such as Smart Labels and many, many others. You are correct: the type of flip chip you ask about requires a lot more processing steps. A Smart label application could never afford it. The key our market advantage is to match up the unmet needs (technical, cost, reliability, etc) of large, rapidly growing market segments with the cost & performance of our technology. NanoPierce has no interest in criticizing other packaging technologies. You never know who we may partner with in the future.

I looked at it and is appears to have more steps in processing: http://www.iep.co.jp/english/tech/index.html Thank you for your anticipated response, Kathy >>>>>>>> Hold NPCT and prosper Jetsia |
