Title: Method and apparatus for alignment of substrate
Inventor: IWANAGA TAKEHIKO
IPC: H01L21/68
Filed: 1992-01-17
Abstract: PURPOSE:To perform a high-accuracy alignment operation by a method wherein the dislocation of a substrate is detected by using a video signal, for alignment use, which is clear without containing any speckle. CONSTITUTION:An alignment mark on a wafer is reflected by a beam of pulsed light, for alignment use, which exposed the wafer 5 and which is emitted from an irradiation system 1; a beam of reflected light is made incident on a CCD camera 9 by using a mirror 8; the dislocation of the wafer 5 is detected by using an obtained video signal; a stage drive system is driven; and the wafer 3 is aligned. The exposure time of the CCD camera 9 is set to be sufficiently long so as to eliminate the speckle of the video signal. When the light quantity for the video signal is insufficient, the exposure time is set to be longer. When the light quantity is excessive, the light-emitting quantity of a light source for the beam of pulsed light for alignment use is reduced.

Title: Method for operating double pipe-type ozonizer
Inventor: ISHIOKA HISAMICHI
IPC: C01B13/11
Filed: 1995-02-15
Abstract: PURPOSE: To provide the method for operating double pipe-type ozonizer, capable of preventing failure of an ozonizer due to streamer development and stably feeding ozone by keeping the peak voltage during discharge constant and stopping output at a point when the output of a high-frequency source is dropped below the lower limit of set value range. CONSTITUTION: During the operation of a double pipe-type ozonizer designed to ozonize a stock gas by applying an alternating voltage between a cylindrical ground electrode 2 with a dielectric layer 3 adhered to the inner surface and a cylindrical high-voltage electrode 4 set concentrically apart from the electrode 2 via a discharge space 5, a high-voltage probe 14 monitors the peak of the alternating voltage, and the resultant information is put to feedback to a high- frequency source 7. For example, in the case where the peak voltage exceeds 10KV, the output of the high frequency source 7 is cut while retaining a specified frequency for the source 7, thereby the peak voltage during discharge is kept at 10KV at all times.  Electric power decrease due to decline in the output affects the process; therefore, the output for the maintenance and inspection of the ozonizer is stopped at a point when the output of the source 7 is lowered below its lower limit.

IPC: H01L21/265
Filed: 1984-02-17
Abstract: PURPOSE:To provide a method of measuring an ion beam diameter in maskless ion implantation in which the diameter of an ion beam also can be measured precisely while the surface of a semiconductor substrate is scanned with that ion beam to detect and record the position of a marker on the substrate. CONSTITUTION:A marker 3 is formed in an edge of a semiconductor substrate 1 of GaAs or the like where no device is to be integrated or formed, by irradiating ions in a high density of 1X10<15>/cm<3> or more with focussing ion beams. After completion of the marker 3, a single crystal layer 4 of GaAs, GaAl:As or the like is grown to a predetermined thickness on the substrate 1 by a molecular beam epitaxy or vapor-phase epipaxy process, while a polycrystalline layer 5 instead of the single crystal layer 4 is grown on the marker 3. Subsequently, focussing ion beams 2 are caused to scan across the boundary 8 between the single crystal layer 4 and the polycrystalline layer 5 in the epitaxial growth layer. Since the single crystal and polycrystalline layers have different semiconductor characteristics, they discharge secondary electrons of different strengths. The discharged secondary electrons 6 are measured by a secondary electron strength measuring amplifier tube. Thus, the position of the marker can be detected.
