Latest Patents
One of his latest patents is titled "Method for forming pad in wafer with three-dimensional stacking structure." This patent discloses a method that includes bonding a device wafer with an Si substrate and a handling wafer, thinning the back side of the Si substrate, and depositing an anti-reflective layer on the thinned back side. The process further involves defining a space for a pad in the back side dielectric layer, forming vias that contact the back sides of super contacts on the Si substrate, and filling these vias with metals. The method concludes with a planarization step using chemical mechanical polishing (CMP) to remove any remnant metal.
Another notable patent is "Image sensor having wave guide and method for manufacturing the same." This invention features a semiconductor substrate with a photodiode and a peripheral circuit region, along with an anti-reflective layer and an insulation layer. The design includes a wiring layer connected to the semiconductor substrate and at least one interlayer dielectric stacked on top. A wave guide is integrated into the structure, passing through the interlayer dielectric and wiring layer above the photodiode.
