Example embodiments of a structure and method for forming a copper interconnect having a doped region near a top surface. The doped region has implanted alloying elements that block grain boundaries and reduce stress and electro migration. In a first example embodiment, the barrier layer is left over the inter metal dielectric layer during the alloying element implant. The barrier layer is later removed with a planarization process. In a second example embodiment the barrier layer is removed before the alloying element implant and a hard mask blocks the alloying element from being implanted in the inter metal dielectric layer.

A structure and method of a semiconductor device with liner air gaps next to interconnects and dielectric layers. A dielectric layer is formed over a lower dielectric layer and a lower interconnect over a substrate. We form an interconnect opening in the dielectric layer. The opening has sidewalls of the dielectric layer. A sacrificial liner is formed over the sidewalls of the interconnect opening. An upper interconnect is formed that fills the opening. We remove the sacrificial liner/spacers to form (air) liner gaps.

A method of manufacturing an integrated circuit provides a substrate having a semiconductor device, and includes forming an intermetal dielectric layer over the substrate and the semiconductor device. A metal wire is formed above the semiconductor device and in contact therewith and a passivation layer is formed over the intermetal dielectric layer. A bond pad is formed connected to the metal wire. A protective moat, with sidewall passivation layer, is formed through the passivation layer and the intermetal dielectric layer, and is located between the metal wire and an outside edge of the integrated circuit.

A method and structure for slots in wide lines to reduce stress. An example embodiment method and structure for is an interconnect structure comprising: interconnect comprising a wide line. The wide line has a first slot. The first slot is spaced a first distance from a via plug so that the first slot relieves stress on the wide line and the via plug. The via plug can contact the wide line from above or below. Another example embodiment is a dual damascene interconnect structure comprising: an dual damascene shaped interconnect comprising a via plug, a first slot and a wide line. The wide line has the first slot. The first slot is spaced a first distance from the via plug so that the first slot relieves stress on the wide line and the via plug.

In accordance with the objectives of the invention a new design and method for the implementation thereof is provided in the form of an “oxide ring”. A conventional die is provided with a guard ring or sealing ring, which surrounds and isolates the active surface area of an individual semiconductor die. The “oxide ring” of the invention surrounds the guard ring or sealing ring and forms in this manner a mechanical stress release buffer between the sawing paths of the die and the active surface area of the singulated individual semiconductor die.

An interconnect structure and method thereof comprising: a interconnect and a compound cap layer. The interconnect has a compound cap layer thereover. The interconnect is preferably comprised of copper. The compound cap layer is preferably comprised of a copper-metal (Cu-Me) compound or a metal; and is more preferably comprised of a Cu—Sn compound or Ni metal. A dielectric cap layer is formed over the compound cap layer. The compound cap layer can provide a barrier capping effect to the Cu to minimize the out-diffusion of Cu and therefore improve the electro-migration performance of Cu. The compound cap layer has excellent adhesion to dielectric cap layers, especially SiN and SiC dielectric cap layers.

Disclosed herein is a gold nanoparticle (AuNP)-based peptide chip prepared by forming a monolayer of AuNPs onto a self-assembled monolayer constructed on a solid support, and then immobilizing a peptide on the AuNPs. The AuNPs can effectively amplify the mass signal of the peptide, thus making it possible to measure the mass change of the peptide in a simple and accurate manner. Also, when secondary ion mass spectrometric analysis (spectrum or imaging) is performed on the AuNP-based peptide chip, the activities of enzymes and related inhibitors can be effectively quantified. The disclosed invention enables various enzyme activities to be analyzed rapidly and accurately, and thus can provide an important method for disease diagnosis and new drug development through the elucidation of signaling and interaction mechanisms.

A drive unit for dish washing machines includes a flow channel housing, a filter housing and an arm holder, which are thermally fused to one another to form an integral unit. Consequently, assembly of the drive unit is simplified, leakage of wash water is prevented, and pumping performance is increased. Also, the flow channel housing, the filter housing and the arm holder are concurrently fixed to a pump housing of the drive unit by fixing members. Consequently, the assembly process of the drive unit is simplified, and the coupling force between the components of the drive unit is increased.
