    摘要: A method of forming a high aspect ratio via opening through multiple dielectric layers, a high aspect ratio electrically conductive via, methods of forming three-dimension integrated circuits, and three-dimensional integrated circuits. The methods include forming a stack of at least four dielectric layers and etching the first and third dielectric layers with processes selective to the second and fourth dielectric layers, etching the second and third dielectric layers with processes selective to the first and second dielectric layers. Advantageously the process used to etch the third dielectric layer is not substantially selective to the first dielectric layer.

    摘要: A method of edge protecting bonded semiconductor wafers. A second semiconductor wafer and a first semiconductor wafer are attached by a bonding layer/interface and the second semiconductor wafer undergoes a thinning process. As a part of the thinning process, a first protective layer is applied to the edges of the second and first semiconductor wafers. A third semiconductor wafer is attached to the second semiconductor wafer by a bonding layer/interface and the third semiconductor wafer undergoes a thinning process. As a part of the thinning process, a second protective layer is applied to the edges of the third semiconductor wafer and over the first protective layer. The first, second and third semiconductor wafers form a wafer stack. The wafer stack is diced into a plurality of 3D chips while maintaining the first and second protective layers.

    摘要: A method, system and program product for bonding two circuitry-including semiconductor substrates, and a related stage, are disclosed. In one embodiment, a method of bonding two circuitry-including substrates includes: providing a first stage for holding a first circuitry-including substrate and a second stage for holding a second circuitry-including substrate; identifying an alignment mark on each substrate; determining a location and a topography of each alignment mark using laser diffraction; creating an alignment model for each substrate based on the location and topography the alignment mark thereon; and bonding the first and second circuitry-including substrates together while aligning the first and second substrate based on the alignment model.
