Latest Patents

One of Wang's latest patents is the "Method for testing a semiconductor device and semiconductor device." This patent describes a test substrate that includes multiple solder bumps, which are employed to test a semiconductor die. The die can be used in two configurations: as a wire-bonded device or a flip-chip device. The design includes test pads that facilitate redundant electrical connections and simplify the testing process. Notably, upon separation from the test substrate, the solder bumps either remain on the substrate or transfer to the die, depending on the desired mounting method. This advancement enables manufacturers to utilize common process flows and die layouts for both device types, resulting in cost savings in both manufacturing and design.

Another important patent is the "Substrate for transferring bumps and method of use." In this invention, Wang outlines a substrate that features two distinct patterns of bumps. During the transfer process, the bumps from the first pattern are transferred to a device, while the second pattern remains intact for future use. This innovative technique enhances the efficiency of the bump transfer process, allowing for more versatile applications in semiconductor packaging.
