Title: The Innovations of Wanming Yu
Introduction
Wanming Yu is a notable inventor based in Tianjin, China. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of Wanming Yu's latest patents is for an MRAM device and method of assembling the same. This invention involves a method of assembling a magnetoresistive random access memory (MRAM) device, which includes providing a substrate with an opening, applying a tape to the substrate's surface, and placing a first magnetic shield within the opening. The process continues with the attachment of an MRAM die to the first magnetic shield and connecting bond pads with wires. A second magnetic shield is then added, followed by the application of an encapsulating material. The method concludes with the attachment of solder balls to the substrate.
Another significant patent is for a thin semiconductor package and method for manufacturing the same. This method involves providing a lead frame with a removable substrate, mounting a semiconductor die on the substrate, and encapsulating the lead frame and die with a first encapsulant. The removable substrate is then taken off to expose the lead frame, allowing for electrical connections to be made. The die and lead frame are encapsulated again with a second encapsulant, and part of the first encapsulant is removed to reduce the package's thickness.
