Abstract:
PURPOSE: A method for controlling a copper layer etching process and a method for regenerating the etchant composition of a copper layer are provided to effectively control a copper layer etching process by using a near infrared spectrometer. CONSTITUTION: A near infrared spectrometer analyzes the density of copper ions of the etchant composition of a copper layer. The lifetime of the etchant composition is determined by comparing the analysis result to a reference value. The reference value is a near infrared ray absorbance rate at a specific wavelength which is in the range of 4,000-12,000cm^-1. The etchant composition includes acid, salt of acid, ammonium salt and water. The light source of the near infrared spectrometer uses the wavelength of 4,000-12,000cm^-1.

Near-IR rays are used to be able to measure calorie, thereby measuring the calorie of an object easily and in a short time by a non-destructive method. A calorie measuring device comprising an object holding unit (1) having a table (2) on which to mount an object (M) to be examined, a light source unit (20) irradiating the object (M) on the table (2) with a near-IR-region ray, a light reception unit (30) receiving a reflection light or transmitted light from the object (M), and a control unit (40) calculating the calorie of the object (M) based on the absorbance of light received by the reception unit (30), wherein the control unit (40) computes the calorie of the object (M) from a regression expression calculated by a quadratic differential spectrum multiple regression analysis at the absorbance of a near-IR ray applied in advance to and reflected off or passed through a calorie-known sample object (M) and from the absorbance of light received by the reception unit (30).

Abstract:
PURPOSE: An infrared sensor is provided to detect infrared rays emitted by an additional projector or a projector installed in a different boundary area by detecting the infrared rays emitted by an additional projector as well as a main projector. CONSTITUTION: An infrared sensor consists of a projector(100) and a receiver(200) sharing specific ID(Identification) data. If infrared rays including ID data are emitted from the projector, the receiver receives the infrared rays and compares the ID data with the received amount of rays to detect interference by approaching of an individual or object, or by a projector of a different boundary area. The projector includes a pulse oscillator(110) generating a carrier for producing infrared rays and ID data, an ID data generator(120) generating ID data periodically to identify projector signals according to the carrier, and a projection unit(130) emitting infrared rays including the ID data to outside. The ID data generator outputs ID data periodically. Herein, the period of generating the ID data is larger than one of the carrier generated from the pulse oscillator. The receiver has a receiving unit(210) receiving infrared rays, an amplifier(220) amplifying the signals of the receiving unit, an isolation decision unit(230) deciding isolation of rays according to the amount of rays included in the output signals of the amplifier, a comparator(240) outputting an alarm signal if the isolation time is longer than predetermined value, an error waveform decision unit(260) outputting an alarm signal if error waveform is interpolated into the received waveform, and an alarming device(250) operated according to the alarm signals. The interference between near infrared sensors is prevented.
