Abstract

A microelectronic die include a die body, the die body is composed of an active surface and a substrate, the active surface is arranged on the top of the substrate, The active surface and the substrate are fixedly connected with the magnetic shielding cover, the outer side of the magnetic shielding cover is filled with a filling material, and the inside of the magnetic shielding cover is respectively provided with a first magnet, a second magnet and a third magnet arranged in a slotted manner. According to the invention, A magnetic field of a plurality of magnetic inductance line with oppositepolarity is generated by a plurality of magnet, and according to the difference of the magnetic conductivity of the magnetic fields, that magnetic inductance lines of external magnetic interference are refracted on an intersection surface between the magnetic inductance lines, thus, the magnetic interference between the die arrangement can be reduced, and the microelectronic die has significant practical advantages, and has broad market prospects and application prospects.

Description

technical field [0001] The invention relates to the technical field of dies, in particular to a microelectronic die. Background technique [0002] The so-called die refers to the chip used to manufacture integrated blocks in integrated circuits. The circuit composed of tens to tens of thousands to N number of electronic components is called an integrated circuit. The chip of this integrated component is the die of the integrated circuit. [0003] After retrieval, the patent No. CN104465568B discloses a stacked microelectronic die embedded in a microelectronic substrate, which is achieved by including at least one first microelectronic die attached to a second microelectronic die, wherein An underfill material is provided between the second microelectronic die and the at least one first microelectronic die. A microelectronic substrate is then formed by laminating the first microelectronic die and the second microelectronic die in the base material. [0004] The analysis fo...
