Latest Patents

One of Daisuke Oka's latest patents is titled "Wafer dicing employing edge region underfill removal." This invention involves a method where a dielectric material layer embedding metal structures is ablated from the chip-containing substrate using laser grooving. This process is performed on the dicing channels of the substrate. An underfill layer is then formed over the dielectric material layer, excluding the peripheral areas of the substrate. The exposed dicing channels at the periphery allow for precise alignment of a blade to dice the substrate. In another embodiment, the underfill layer is formed before any laser grooving, followed by mechanical cutting and laser ablation to achieve the desired dicing.

Another notable patent is the "Epoxy resin composition for encapsulating semiconductor and semiconductor device." This invention provides an epoxy resin composition that includes a crystalline epoxy resin with a melting point between 50°C and 150°C, along with other specific epoxy resins. This composition is designed to enhance the encapsulation of semiconductors, ensuring better performance and reliability.
