Latest Patents

Yen-Shih Ho's latest patents include a semiconductor device and fabrication method. This method involves providing a substrate that consists of a handle substrate, a bottom cladding layer, and a semiconductor layer stacked in sequence. The substrate features an electronic integrated circuit (EIC) region and a photonic integrated circuit (PIC) region. A thermal oxidation process is performed on the semiconductor layer in the PIC region to form an oxide layer. The first thickness of the semiconductor layer in the EIC region is greater than the second thickness of the semiconductor layer below the oxide layer. After the oxide layer is removed, a PIC structure is formed on the bottom cladding layer in the PIC region, while an EIC structure is formed on the bottom cladding layer in the EIC region. An interconnect structure is then created to electrically connect the PIC and EIC structures.

Another notable patent is the structure of transferring dies for use in a mass transferring process. This structure includes an oxide layer supporting feature, multiple dies, a bonding feature, a supporting wafer, and a spacer. The oxide layer supporting feature consists of multiple repeating units, each with a die setting region and a peripheral region. The die is placed on the die setting region, while the bonding feature is positioned on the peripheral region of the oxide layer supporting feature. The supporting wafer is located beneath the oxide layer supporting feature, separated from the die and bonding feature by a gap. The spacer is situated between the bonding feature and the supporting wafer, bonded to the bonding feature.
