A novel passivation structure and its method of fabrication. According to the present invention a first dielectric layer is formed upon a conductive layer formed over a substrate. The first dielectric layer and the conductive layer are then patterned into a first dielectric capped interconnect and a dielectric capped bond pad. Next, a second dielectric layer is formed over and between the dielectric capped interconnect and the dielectric capped bond pad. The top portion of the second dielectric layer is removed so as to expose the dielectric capped bond pad and the dielectric capped interconnect. A third dielectric layer is then formed over the exposed dielectric capped bond pad and the exposed dielectric capped interconnect and over the second dielectric.
The present invention provides a method of forming a bonding pad on a semiconductor chip such that peeling of bonding pads during interconnection in the packaging process is avoided. The bonding pad is used to electrically connect an integrated circuit in the semiconductor chip with an external circuit. The method comprises forming a first dielectric layer at a predetermined area on the surface of the semiconductor chip, forming a second dielectric layer on the surface of the semiconductor chip outside the predetermined area wherein the first dielectric layer is harder than the second dielectric layer, and forming the bonding pad on the first dielectric layer.
A semiconductor device has: a semiconductor substrate having a surface which has a predetermined pattern, in which an insulating layer is embedded; an interlayer insulator film formed on the substrate, the interlayer insulator film having a protective coat for protecting the substrate; and an electrode formed on the interlayer insulator film. In addition, a method for manufacturing a semiconductor device comprises the steps of: forming a semiconductor substrate having a surface which has a groove in which an insulating layer is embedded; forming a protective coat for protecting the surface of the semiconductor substrate, on the upper surface of the insulating layer embedded in the groove; and forming an electrode on the protective coat. According to the semiconductor device and the method for manufacturing the same, it is possible to more sufficiently planarize the surface of the insulating layer by the rotary polishing method, and it is possible to decrease the bonding damage applied to a underlayer portion serving as a bed of the semiconductor device when carrying out the wire bonding.

The invention includes a semiconductor construction having a wire bonding region associated with a metal-containing layer, and having radiation-imageable material over the metal-containing layer. The radiation-imageable material can be configured as a multi-level pattern having a first topographical region with a first elevational height and a second topographical region with a second elevational height above the first elevational height. The second topographical region can be laterally displaced from the bonding region by at least a lateral width of the first topographical region, with said lateral width being at least about 10 microns. Additionally, or alternatively, the elevational height of the second topographical region can be at least about 2 microns above the elevational height of the first topographical region. The invention also includes a method of forming wire bonds for semiconductor constructions in which a multi-level pattern is photolithographically formed in a radiation-imageable material (such as, for example, polyimide).
A metal-containing layer is formed on a substrate. A mask layer is formed on the metal-containing layer. The mask layer is patterned by way of a lithographically fabricated mask. The metal-containing layer is patterned with the patterned mask layer, to thereby form an electrode out of the metal-containing layer. A protective layer is deposited on the mask layer and on the substrate. The protective layer undergoes chemical mechanical polishing, during which the protective layer is removed and the electrode is uncovered.
