MRAM DEVICE AND METHOD OF ASSEMBLING SAME |
摘要 |
A method of assembling a magnetoresistive random access memory (MRAM) device includes providing a substrate having an opening. A tape is applied to a surface of the substrate and a first magnetic shield is placed onto the tape and within the substrate opening. An adhesive is applied between the first magnetic shield and the substrate to attach the first magnetic shield to the substrate. An MRAM die is attached to the first magnetic shield and bond pads of the MRAM die are connected to pads on the substrate with wires. A second magnetic shield is attached to a top surface of the MRAM die. An encapsulating material is dispensed onto the substrate, the MRAM die, the second magnetic shield and part of the first magnetic shield, cured, and then the tape is removed. Solder balls then may be attached to the substrate.
