    • The present invention pertains to a device and a method for measuring a via hole of a silicon wafer, wherein it is possible to precisely measure the depth of the via hole without damaging the wafer. Broadband infrared light is radiated to a silicon wafer which has a superior light transmission property, so that the depth of the via hole may be measured from the light which is reflected from each boundary surface of the wafer and the interference signal of reference light. The via hole measuring device according to the present invention includes: a light source unit for generating broadband infrared light; and an interferometer for radiating the light generated from the light source unit to a silicon wafer, so as to measure the depth of a via hole formed on the wafer according to the spectrum period of the interference signal of the light, which is reflected from the silicon wafer.

    • A frequency-stabilized laser apparatus and a method for stabilizing the frequency of a laser are disclosed. A semiconductor laser emits a beam. An external reflector has a resonance frequency and feeds back the emitted beam to the semiconductor laser if the frequency of the emitted beam is equal to the resonance frequency. An interference signal generator generates an interference signal for detecting the wavelength of the emitted beam and a controller detects the wavelength of the beam from the generated interference signal. According to the frequency-stabilized laser apparatus and the method for stabilizing the frequency of the laser, it is possible to stabilize the frequency of the beam emitted from the semiconductor laser and output the beam having the stable frequency for a long period of time.
    • 公开了一种频率稳定的激光装置和用于稳定激光器的频率的方法。 半导体激光器发射光束。 如果发射光束的频率等于谐振频率,则外部反射器具有谐振频率并将发射的光束反馈到半导体激光器。 干扰信号发生器产生用于检测发射波束的波长的干扰信号,并且控制器根据所产生的干扰信号来检测波束的波长。 根据频率稳定的激光装置和稳定激光的频率的方法,可以使从半导体激光器发射的光束的频率稳定并输出长时间具有稳定频率的光束。
