Chip with information identification and preparation method of chip

Abstract

The invention provides a chip with information identification, wherein the chip comprises a label circuit, a chip antenna, a chip core and a pad ring; the label circuit comprises a radio frequency analogue circuit, a digital circuit module and a memory; the chip antenna is connected to the radio frequency analogue circuit, the radio frequency analogue circuit is connected to the digital circuit module, the digital circuit module is connected to the memory, the chip core is arranged on the centre of the pad ring and is connected to the pad of the pad ring; the preparation method comprises the following steps of: forming a FRID (Radio Frequency Identification) label circuit into a module which is the same with the width of the chip pad, then directly placing the layout of a FRID module in the position of the chip pad, placing a FRID chip antenna inside or outside the pad ring in the chip layout, and then making plate and processing to produce a chip with embedded electric identificationinformation, wherein the identification information in the chip is written into or read from the chip through a card reader. The chip with information identification and the preparation method of thechip have the advantages that the reliability for the method of embedding the identification information of the chip is high, the cost is prevented from increasing, and the chip has great applicationvalues in anti-fake, management and identification field of the chip.

Description

technical field [0001] The invention belongs to the technical field of RFID identification, and in particular relates to a chip with information identification and a preparation method thereof. Background technique [0002] The identification information of the chip mainly includes the chip model, function, technical parameters, design manufacturer, batch, etc. The identification information of traditional chips in the market is mainly concentrated in three places, the outer packaging of the chip, the package of the chip and the core of the chip. The logo on the chip package is easy to copy, and it is not easy to save for a long time; the logo information of the chip package shell and core can be erased by means of chip text correction fluid, polishing, etc., and it is easy to re-mark, which makes the chip counterfeit. In the market, CPU chips and video card chips are used as good ones, old ones are replaced with new ones, and fake ones happen from time to time. At the same ...

[0002] The identification information of the chip mainly includes the chip model, function, technical parameters, design manufacturer, batch, etc. The identification information of traditional chips in the market is mainly concentrated in three places, the outer packaging of the chip, the package of the chip and the core of the chip. The logo on the chip package is easy to copy, and it is not easy to save for a long time; the logo information of the chip package shell and core can be erased by means of chip text correction fluid, polishing, etc., and it is easy to re-mark, which makes the chip counterfeit. In the market, CPU chips and video card chips are used as good ones, old ones are replaced with new ones, and fake ones happen from time to time. At the same time, there are many organizations and companies that polish and change chips designed by others. In exchange for relevant benefits, the traditional chip identification method uses text or graphic identification, which has less information and is inconvenient for intelligent management
