Abstract: The present invention relates to a material having various functions such as antimicrobial function or waterproof function, as well as a method and an apparatus for manufacturing the same. The method for manufacturing a functional material according to the present invention includes coating a surface of conductive or non-conductive material with an electrically charged microfine material having a size of nano- or micro-units, thereby imparting functionality to the material simultaneously with maintaining intrinsic properties thereof.

Abstract: An apparatus and a method for interlocking power to ion implantation equipment. The apparatus may include a positive and a negative power supply which generates a positive voltage and a negative voltage respectively, a comparator which compares the positive voltage and the negative voltage, and a signal generating unit which generates an interlocking signal which interlocks the positive and negative power supplies when a sum of a first relative value of the positive voltage and a second relative value of the negative voltage does not equal zero. The apparatus may further include a switching unit which changes a mode of the positive and negative power supplies from a remote mode to a local mode when the sum of the relative values does not equal zero. The switching unit may be a relay switch. Power output lines may connect the positive and negative power sources to a lens assembly unit.

Abstract: An apparatus for aligning a wafer is provided, which normally senses a flat zone of the wafer by sensors regardless of an external light so that the wafer is aligned in a set mode, in order to increase or maximize production yield. A body has all kinds of drivers. An orient chuck is provided to protrude to an upper portion of the body for rotating the wafer; a guide plate ascending and descending to slide a circumference surface of the wafer so that a center of the wafer is located on the orient chuck. A plurality of sensors sense a flat zone of the wafer being rotated on the orient chuck. A wafer carrier cassette is formed at an upper portion of the orient chuck in order to load the wafer aligned in one direction by the sensors and the orient chuck, and is supported by a plurality of frames formed at respective corners of the body.

Abstract: A high-energy ion implanter monitors the recycling of a charge exchanging gas that is supplied to a stripper of a tandem accelerator. When the charge exchanging gas leaks out from the stripper and then flows into both energy boxes adjacent the tandem accelerator, gas sensors in the energy boxes measure the amount of the charge exchanging gas and send corresponding data to a controller. The controller compares the measured data with a standard data on the charge exchanging gas. When the measured data is different from the standard data, a pre-established interlocking system breaks off the operation of the implanter.

Abstract: An ion implantation apparatus for use in manufacturing semiconductors includes a loopback device connected to a bias ring for a Faraday cup. The loopback device detects whether a current flows through the bias ring and generates an interlock signal to be supplied through an interface to a controller. In response to the interlock signal, the controller stops an implantation operation of the apparatus, and a driver circuit drives a warning device in response to the interlock signal.
