Disclosed is a polishing slurry, particularly, a slurry for chemical mechanical polishing, which is used in a chemical mechanical polishing process for flattening a semiconductor laminate. More particularly, the present invention provides a method of producing a slurry which has high removal selectivity to a nitride layer used as a barrier film in a shallow trench isolation CMP process needed to fabricate ultra highly integrated semiconductors of 256 mega D-RAM or more (Design rule of 0.13 μm or less) and which decreases the occurrence of scratches on a flattened surface, and a method of polishing a substrate using the same.

Provided is an electron beam lens for a micro-column electron beam apparatus and a method of manufacturing the same. A photosensitive glass substrate is used as a base isolation substrate and a thin metal film is grown by a plating method. Holes through which electron beam passes are formed by a lift off method after forming a resist pattern shaped as a hole on a seed metal layer and plating the thin metal film.

Disclosed herein is a polishing slurry for chemical mechanical polishing. The polishing slurry comprises polishing particles, which have a particle size distribution including separated fine and large polishing particle peaks. The polishing slurry also comprises polishing particles, which have a median size of 50-150 nm. The present invention provides the slurry having an optimum polishing particle size, in which the polishing particle size is controlled and which is useful to produce semiconductors having fine design rules by changing the production conditions of the slurry. The present invention also provides the polishing slurry and a method of producing the same, in which a desirable CMP removal rate is assured and scratches are suppressed by controlling a polishing particle size distribution, and a method of polishing a substrate.
摘要:
A method of fabricating a transistor in a semiconductor device. A gate oxide layer and a gate are formed on a semiconductor substrate. An oxide layer and a silicon nitride layer are stacked on the substrate. The stacked oxide and silicon nitride layers are etched back to expose a surface of the substrate. The silicon nitride layer is removed to form a gate sidewall spacer. Impurity ions are implanted into the substrate through the exposed surface of the substrate.

A latch type optical communication module, designed to9 be easily mounted and detached to a system port having a cage by means of a latch. The optical communication module is provided with a latch: The latch may be rotated around a hinge shaft fixed to both sides of a receptacle while being inserted into latch holes penetrating both ends of the latch. When the latch is rotated and then allows latch drivers to force a slider upward, the slider raises a fixing tap of the optical communication module inserted into the system port, thereby allowing the optical communication module to be detached from the system port. With the construction of the optical communication module, the plurality of additional components are not required for the optical communication module, thereby lowering manufacturing costs, and the optical communication module can be detached from the system port without any tool and any influence against adjacent optical communication module.

A color reproduction correcting system and method, and a video display device and method can reproduce original color by considering signal source and display device. Each signal source information and each display device information can be stored. The signal source and the display device, which are currently used (e.g., corrected), can be determined, for example, by a user selection. In one embodiment, the signal provided from a transmission side can be inverse gamma-corrected based on a corresponding signal source, and a colorimetric error of the inverse gamma-corrected signal is preferably corrected using corresponding signal source information and display device information. The corrected colorimetric error signal can be gamma-corrected based on a corresponding display device and then can be displayed on the corresponding display device.
