  • Publication number: 20140008763
    Abstract: Capacitor device structures can be fabricated on a substrate including multiple separate first electrodes and a common distributed second electrode. The second electrode can be common to the multiple first electrodes and can be distributed in a shape of a grid interdigitating the multiple first electrodes. The distributed nature of the second electrode can replace the substrate backside as the bottom electrode and can reduce the device parasitic characteristics. In some embodiments, the capacitor device structures can be used in a high productivity combinatorial process, wherein the distributed nature of the second electrode can make the test structures more tolerant to misalignment.

In this manner, in the present invention, the through wiring board formed of only a core layer is used, so that it is not required to consider a difference in thermal expansion coefficient between a build-up layer and the core layer, and besides, it is not required either to consider the electrical disconnection of a fine via formed in the build-up layer because the build-up layer does not exist. As a result, according to the present invention, the reliability of the semiconductor device can be improved while a cost is reduced.

A first dielectric layer is formed over the first barrier layer. An opening is formed in the first dielectric layer, wherein the opening runs through the first dielectric layer, so that the first barrier layer is exposed to the opening. A metal deposition process is performed to form a metal line over the exposed first barrier layer at a bottom of the opening. The first dielectric layer and the first barrier layer underlying the first dielectric layer are removed, but the metal line and the first barrier layer underlying the metal line are remained. Afterwards, a second dielectric layer is formed over the substrate which is provided with the metal line and the first barrier layer.

    Abstract: A submicron connection layer and a method for using the same to connect wafers is disclosed. The connection layer comprises a bottom metal layer formed on a connection surface of a wafer, an intermediary diffusion-buffer metal layer formed on the bottom metal layer, and a top metal layer formed on the intermediary diffusion-buffer metal layer. The melting point of the intermediary diffusion-buffer metal layer is higher than the melting points of the top and bottom metal layers. The top and bottom metal layers may form a eutectic phase. During bonding wafers, two top metal layers are joined in a liquid state; next the intermediary diffusion-buffer metal layers are distributed uniformly in the molten top metal layers; then the top and bottom metal layers diffuse to each other to form a low-resistivity eutectic intermetallic compound until the top metal layers are completely exhausted by the bottom metal layers.

    Abstract: Methods of forming a conductive metal layer over a dielectric layer using plasma enhanced atomic layer deposition (PEALD) are provided, along with related compositions and structures. A plasma barrier layer is deposited over the dielectric layer by a non-plasma atomic layer deposition (ALD) process prior to depositing the conductive layer by PEALD. The plasma barrier layer reduces or prevents deleterious effects of the plasma reactant in the PEALD process on the dielectric layer and can enhance adhesion. The same metal reactant can be used in both the non-plasma ALD process and the PEALD process.
