摘要:
A method of manufacturing a microelectronic device including, in one embodiment, providing a substrate having a plurality of partially completed microelectronic devices including at least one partially completed memory device and at least one partially completed transistor. At least a portion of the partially completed transistor is protected by forming a first layer over the portion of the partially completed transistor to be protected during a subsequent material removal step. A second layer is formed substantially covering the partially completed memory device and the partially completed transistor. Portions of the second layer are removed leaving a portion of the second layer over the partially completed memory device. At least a substantial portion of the first layer is removed from the partially completed transistor after the portions of the second layer are removed.

An image sensor device and fabrication method thereof. An image sensing array is formed in a substrate, wherein the image sensing array comprises a plurality of photosensors with spaces therebetween. A first dielectric layer with a first refractive index is formed overlying the spaces but not the photosensors. A conformal second dielectric layer with a second refractive index is formed on a sidewall of the first dielectric layer. A third dielectric layer with a third refractive index is formed overlying the photosensors but not the spaces. The third refractive index is greater than the second refractive index. A light guide constructed by the second and third dielectric layers is formed overlying each photosensor, thereby preventing incident light from striking other photosensors.

A novel method for forming electrodes in the fabrication of an MIM (metal-insulator-metal) capacitor, is disclosed. The method improves MIM capacitor performance by preventing plasma-induced damage to a dielectric layer during deposition of a top electrode on the dielectric layer, as well as by reducing or preventing the formation of an interfacial layer between the dielectric layer and the electrode or electrodes, in fabrication of the MIM capacitor. The method typically includes the patterning of crown-type capacitor openings in a substrate; depositing a bottom electrode in each of the crown openings; subjecting the bottom electrode to a rapid thermal processing (RTP) or furnace anneal step; depositing a dielectric layer on the annealed bottom electrode; depositing a top electrode on the dielectric layer using a plasma-free CVD (chemical vapor deposition) or ALD (atomic layer deposition) process; and patterning the top electrode of each MIM capacitor.

Provided is a method of fabricating a semiconductor device. The method includes forming a first III-V family layer over a substrate. The first III-V family layer includes a surface having a first surface morphology. The method includes performing an ion implantation process to the first III-V family layer through the surface. The ion implantation process changes the first surface morphology into a second surface morphology. After the ion implantation process is performed, the method includes forming a second III-V family layer over the first III-V family layer. The second III-V family layer has a material composition different from that of the first III-V family layer.

A phase change memory and a method of manufacture are provided. The phase change memory includes a layer of phase change material treated to increase the hydrophobic nature of the phase change material. The hydrophobic nature of the phase change material improves adhesion between the phase change material and an overlying mask layer. The phase change material may be treated, for example, with a plasma comprising N2, NH3, Ar, He, O2, H2, or the like.

A method for reducing leakage current in a semiconductor structure is disclosed. One or more dielectric layers are formed on a semiconductor substrate, on which at least one device is constructed. A hydrogen-containing layer is formed over the dielectric layers. A silicon nitride passivation layer covers the dielectric layers and the hydrogen-containing layer. The hydrogen atoms of the hydrogen-containing layer are introduced into the dielectric layers without being blocked by the silicon nitride layer, thereby reducing leakage current therein.
