Abstract: Provided are methods for manufacturing improved cerium oxide abrasives suitable for forming slurry compositions suitable for CMP processes. The cerium oxide abrasives are produced by the heat treatment of a mixture of a cerium precursor compound under conditions that produce primary cerium oxide particles that are incorporated in larger secondary abrasive particles. The structure of the primary cerium oxide particles and/or the presence of incompletely oxidized cerium within the secondary abrasive particle tend to reduce its mechanical strength, thereby reducing the likelihood of damaging a substrate surface during a CMP process utilizing such abrasives.

Abstract: Disclosed herein are an apparatus and method for testing open and short circuits of conductive lines. A probe is brought into contact with one end of each of the conductive lines, AC power is applied, and the conductive lines are tested using electrical variations measured in the probe. By using a single-side probe device, it is possible to remarkably reduce the number of probes when the open or short circuit of a PCB pattern, a data transmission line or an electrical cable is tested and to remarkably reduce time or labor necessary for testing the open or short circuit. Since the measurement is performed only at one end of the conductive line to test the open or short circuit of the conductive line, it is possible to self-diagnose the open or short circuit when a single-side probe device is mounted in an input/output port of an electrical device.

Abstract: A terminal location estimation method in a wireless communication system in which an access point (AP) provides an access service to a plurality of terminals includes defining a plurality of beam spaces around the AP through space multiplexing; scheduling the beam spaces according to a predetermined pattern; simultaneously forming a beam in at least one beam space; and detecting the existence and location of a terminal according to whether a response message in response to the formed beam is received. Accordingly, an AP forms beams in a predetermined scheduling pattern, and each of the terminals detecting the beams registers its location by informing the AP that each of the terminals exists in a relevant beam area, and thus, a location of each of the terminals can be estimated without using a complex DOA algorithm.
