Inventor: SHIBAZAKI YUICHI
IPC: G03F9/00
Filed: 2008-08-25
Abstract: Positional information of a wafer stage (WST) in a Z-axis direction and a tilt direction with respect to the XY plane (for example, a Θy direction) is measured, using a surface position measurement system, such as, for example, a Z head (72b, 72d) and the like, and the wafer stage is driven based on the measurement results. At the same time, positional information of the wafer stage is measured using an interferometer system such as, for example, a Z interferometer (43A, 43B). When abnormality of the surface position measurement system is detected or when the wafer stage moves off from a measurement area of the surface position measurement system, drive control is switched to a drive control based on the measurement results of the interferometer system. Accordingly, the wafer stage can be driven continuously even at the time of abnormality generation in the surface position measurement system.

The coupling bolt is connected to a vertical panel which is orthogonal with the horizontal panel. A head unit(21) of the coupling bolt is inserted into a cam groove(12) which is eccentric to the fastening ring. If the fastening ring is rotated, the head unit is pulled and the horizontal panel and vertical panel are combined. The protrusions(13) are formed around a fixed point in the inner circumference of the cam groove. When a recess unit(23) formed at the lower end of the head unit goes over the protrusions, the rotation of the fastening ring is stopped. A cut-out part(14) is formed right on top of the protrusions on the outer circumference of the fastening ring.

Title: Metal-oxide semiconductor gas sensor with nanostructure and manufacturing method thereof
IPC: B82B3/00
Filed: 2011-04-27
Abstract: PURPOSE: A metal oxide semiconductor gas sensor having a nano structure and a manufacturing method thereof are provided to enhance the sensitivity of a gas sensor by allowing each contact between a target gas and a gas sensing layer because a metal oxide semiconductor having a nano structure, formed by using an oblique angle deposition method, is used as the gas sensing layer. CONSTITUTION: A metal oxide semiconductor gas sensor having a nano structure comprises a substrate(100), a first electrode(200), a gas sensing layer(300), a second electrode(400), and a controlling unit(500). The first electrode is formed on the top of the substrate. The gas sensing layer has a nano structure and is composed of a metal semiconductor. The gas sensing unit reacts with a target gas so that the electrical conductivity is changed. The gas sensing layer is formed by an oblique angle deposition method. The second electrode is formed on the top of the metal oxide semiconductor. The controlling unit measures the electrical conductivity of the gas sensing layer by letting predetermined current flow through the first and second electrodes, thereby sensing the target gas.

Title: Semiconductor device and method for fabricating the same
IPC: H01L21/8242
Filed: 2011-04-29
Abstract: PURPOSE: A semiconductor device and a manufacturing method thereof are provided to prevent the reduction of a dielectric layer due to hydrogen in a carbon metal nitride layer by inserting a reduction preventing layer between a carbonized metal nitride layer and a dielectric layer. CONSTITUTION: A capping layer(42) is formed. A carbonized metal nitride layer is formed on the capping layer. A reduction preventing layer is formed on the carbonized metal nitride layer. A dielectric layer(302) made of metal oxide layer is formed on the reduction preventing layer. The capping layer, the carbonized metal nitride layer, and the reduction preventing layer are formed with in-situ in the same chamber.
