  • Porogen bonded gap filling material in semiconductor manufacturing
    Patent number: 11984316
    Abstract: A device includes a substrate; a first layer over the substrate, the first layer containing a plurality of fin features and a trench between two adjacent fin features. The device also includes a porous material layer having a first portion and a second portion. The first portion is disposed in the trench. The second portion is disposed on a top surface of the first layer. The first and the second portions contain substantially same percentage of Si, substantially same percentage of O, and substantially same percentage of C.

  • SEMICONDUCTOR STRUCTURE AND METHOD MAKING THE SAME
    Publication number: 20240088025
    Abstract: The present disclosure provides a method for forming an integrated circuit (IC) structure. The method comprises providing a substrate including a conductive feature; forming aluminum (Al)-containing dielectric layer on the conductive feature; forming a low-k dielectric layer on the Al-containing dielectric layer; and etching the low-k dielectric layer to form a contact trench aligned with the conductive feature. A bottom of the contact trench is on a surface of the Al-containing dielectric layer.

  • Pneumatic steel bar binding machine mechanism
    Patent number: 6488055
    Abstract: A pneumatic steel bar binding machine mechanism to bind two or more column-shaped steel bars together, or specifically, a machine to bind the steel frames inside the concrete framework in construction works, characterized in a pneumatic mechanism and a spiral twister that press steel staples in the shape of reversed-U onto the steel bars to be bound, before the spiral twister is driven to twist the two ends of the steel staple into a twisted rope, to secure the steel bars.
