  • Patent number: 11973027
    Abstract: A semiconductor device and a method of forming the same are provided. The semiconductor device includes a substrate, a gate structure, a dielectric structure and a contact structure. The substrate has source/drain (S/D) regions. The gate structure is on the substrate and between the S/D regions. The dielectric structure covers the gate structure. The contact structure penetrates through the dielectric structure to connect to the S/D region. A lower portion of a sidewall of the contact structure is spaced apart from the dielectric structure by an air gap therebetween, while an upper portion of the sidewall of the contact structure is in contact with the dielectric structure.

  • Publication number: 20240128231
    Abstract: Semiconductor devices and methods of manufacturing the semiconductor devices are presented. In embodiments the methods of manufacturing include depositing a first bonding layer on a first substrate, wherein the first substrate comprises a semiconductor substrate and a metallization layer. The first bonding layer and the semiconductor substrate are patterned to form first openings. A second substrate is bonded to the first substrate. After the bonding the second substrate, the second substrate is patterned to form second openings, at least one of the second openings exposing at least one of the first openings. After the patterning the second substrate, a third substrate is bonded to the second substrate, and after the bonding the third substrate, the third substrate is patterned to form third openings, at least one of the third openings exposing at least one of the second openings.

  • Patent number: 8048599
    Abstract: A color filter fabricated by an ink jet process is disclosed. The color filter includes a substrate, a plurality of pixel regions positioned on the surface of the substrate, and a plurality of colored photoresists. Each pixel region includes a plurality of sub-pixel regions, and each colored photoresist is positioned in each sub-pixel region. The colored photoresists include a plurality of hydrophile photoresists and a plurality of hydrophobic photoresists. The hydrophile photoresists and the hydrophobic photoresists are alternately arranged to prevent an overflow of the colored photoresists.
