A method for forming a semiconductor device with a bonding pad is disclosed. A first substrate having a device area and a bonding area is provided, wherein the first substrate has an upper surface and a bottom surface. Semiconductor elements are formed on the upper surface of the first substrate in the device area. A first inter-metal dielectric layer is formed on the upper surface of the substrate in the bonding area.

摘要:
A method includes forming an amorphous carbon layer over a first dielectric layer formed over a substrate, forming a second dielectric layer over the amorphous carbon layer; and forming an opening within the amorphous carbon layer and second dielectric layer by a first etch process to partially expose a top surface of the first dielectric layer. A substantially conformal metal-containing layer is formed over the second dielectric layer and within the opening. The second dielectric layer and a portion of the metal-containing layer are removed. The amorphous carbon layer is removed by an oxygen-containing plasma process to expose a top surface of the first dielectric layer. An insulating layer is formed over the metal-containing layer, and a second metal-containing layer is formed over the insulating layer to form a capacitor.

摘要:
A method includes the steps of: (a) forming a conductive layer within a dielectric layer formed over a substrate; (b) forming a material layer over the conductive layer and the dielectric layer; (c) forming an opening within the material layer by an etch process to expose a portion of the dielectric layer and a top surface of the conductive layer; (d) forming a first metal-containing layer within the opening substantially covering sidewalls of the material layer and the exposed portion of the second dielectric layer; and (e) removing the material layer by an oxygen-containing plasma process to expose a portion of outer sidewalls of the first metal-containing layer.

摘要:
An image sensor includes a double-microlens structure with an outer microlens aligned over an inner microlens, both microlenses aligned over a corresponding photosensor. The inner or outer microlens may be formed by a silylation process in which a reactive portion of a photoresist material reacts with a silicon-containing agent. The inner or outer microlens may be formed by step etching of a dielectric material, the step etching process including a series of alternating etch steps including an anisotropic etching step and an etching step that causes patterned photoresist to laterally recede. Subsequent isotropic etching processes may be used to smooth the etched step structure and form a smooth lens. A thermally stable and photosensitive polymeric/organic material may also be used to form permanent inner or outer lenses. The photosensitive material is coated then patterned using photolithography, reflowed, then cured to form a permanent lens structure.
