摘要:
According to the present invention, in making alignment between a semiconductor integrated circuit wafer and a mask or a reticle in light exposure of the wafer with a monochromatic light such as g-, i- or h- line of a mercury lamp, using a reduced stepping exposure system, light from a predetermined pattern on the wafer is taken out to an off-axis position and observed according to a through-the-lens method; in this case as a characteristic feature of the invention, the observation light is taken out from below the reticle and is passed through chromatic aberration correcting lenses, thereby permitting the use of a polychromatic or continuous spectrum light.

The invention deals with an exposure apparatus which detects environmental conditions such as atmospheric pressure, temperature and humidity in which the exposure apparatus is placed, and which maintains the projected magnification constant at all times based upon the detected values, so that the pattern can be reproduced precisely. Concretely, the apparatus comprises a detector to detect at least one of the tube temperature of the optical projecting system, humidity or atmospheric pressure near the optical system, and a control unit which controls optical characteristics based upon the signals detected by the detector. Namely, the control unit adjusts the optical characteristics depending upon the environmental conditions thereby to adjust variation in the projecting magnification and/or variation in the focal position. Thus, variation in the optical characteristics is adjusted to transfer the pattern maintaining high precision.

The independencies of a plurality of layers executing dividingly a transaction can be easily enhanced. Anode (30) assigns to a transaction to anode (30) of a lower layer through a distributed transaction management section. The node (30) shares a predetermined transaction with the node (30) of the lower layer along with other nodes (30). The node (30) shared by the nodes (30) is a read-only node or a node to which data can be written by the characteristic of a function. Thus the node (30) searches for an unused node (30) in lower layers through the distributed transaction management section (34) when the node starts a new transaction. First, second, and third node hosts (3,4,5) check if each node (30) is used for which transaction or if each node (30) is used or not and store the results.

Data and/or services associated with a given object are easily searched by using a search system having a global unique object identifier, a metadata store, an input for entering the global unique identifier, a metadata reader for reading a set of metadata including the input global unique identifier from the metadata store, and a metadata search engine for searching for specific metadata by searching for a specific description sentence included in each metadata of the read set of metadata.
摘要:
A film deposition apparatus and a method thereof for accurately forming a film of a given thickness on the surface of a wafer is described. The film deposition apparatus includes a laser beam to perform a precise in-situ monitoring of a change in thickness of the film being deposited on the surface of the wafer. An optical guide is provided in an attachment coupled to the quartz furnace of a chemical vapor deposition apparatus. A laser beam is introduced into the quartz furnace through the optical guide, and is projected onto the wafer. The laser beam reflected by the wafer is channeled through the same optical guide to be discharged to the outside of the quartz furnace. A change in thickness of the film is monitored based on the strength of the reflected laser beam. In this manner, the laser beam can be transmitted without passing through the wall of the quartz furnace, and the thickness of the film can be accurately monitored without the process being affected by the thin film deposited on the internal wall of the quartz furnace.
