Title: Manufacture of semiconductor device
Inventor: FUJIMORI TAKASHI
IPC: H01L29/43
Filed: 1989-05-10
Abstract: PURPOSE:To enhance the adhesion between a silicide alloy and a wiring layer thereby enabling an electrode in high reliability to be formed by a method wherein a formed silicide film is laser-annealed to form a wiring alloy on the annealed silicide film. CONSTITUTION:After forming the first layer wiring 1 comprising a polycide structure, an interlayer film 2 is deposited to make a contact hole 5. Next, a part of the first layer wiring 1 as the lower layer exposed to the contact hole 5 is laser-annealed. Then, an Al alloy film 6 to be the second layer wiring is deposited. At this time, the surface of a silicide alloy 3 is flattened so that the junction area with the Al alloy 1 in interface may be reduced to minimize the compound reaction in the interface. Through these procedures, the adhesion between the silicide alloy 3 and the wiring layer 1 can be enhanced thereby enabling an electrode in high reliability to be formed.

Abstract: PURPOSE:To obtain a metal or semiconductor flat thin film, which is dense and has a large adhesive strength even at low temperatures and has a good crystallizability, by a method wherein, while an evaporating material is being evaporated on the sample substrate, the laser beams to be emitted from the laser are projected on the sample substrate from the reverse side to the evaporating surface and surface plasmon is caused on the vacuum side of the evaporated film. CONSTITUTION:Laser beams 12 to be emitted from a laser 11 are made incident in a prism 15 to be installed in the interior of a vacuum chamber 13 through the window 14 of the vacuum chamber 13. An evaporating material 20 to be put in an evaporation boat 19 is heated in a vacuum and is turned into vapor and the vapor is evaporated on a sample substrate 16 through a mask 21. The evaporation is executed in a state that the laser beams 12 are being projected on the sample substrate 16 and when an evaporated film 25 begins to be formed, surface plasmon can be excited on the vacuum side of the evaporated film 25 by ready-selecting the wavelength of the laser beams 12 and an incident angle 17 at a proper value each. The excitation of the surface plasmon can be judged by monitoring the attenuation of a reflected light 26.

Title: Temperature detector
Inventor: TABUCHI SADATOSHI
IPC: G01K7/24
Filed: 1988-05-13
Abstract: PURPOSE:To improve the accuracy on the high-temperature side of a measured temperature range and to accurately detect temperature by signal to the time when a capacitor reaches a charging and voltage, and detecting the temperature of a temperature detecting element. CONSTITUTION:When the temperature of a thermistor 5 is below the upper limit of a detection range, the output of a comparator 16 is low in the turned on state of a transistor TR12 and a TR 11 turns on to charge the capacitor 2. When the voltage of the capacitor 2 exceeds the output voltage of a charging end voltage generation part 13, the output of the comparator 16 becomes high. Namely, a control means 17 holds a terminal at high level to turn on the TR 12 and then the time up to when the output of the comparator 16 goes to high, namely, when a terminal (i) of the means 17 goes to high is measured, so that the temperature of the thermistor 5 can be measured and displayed on a display means 18. Consequently, the variance of a charging circuit exerts no influence upon the high-temperature side and the temperature detection is accurately performed.

Title: Defect inspection method
Inventor: NAKANISHI MINORU
IPC: G06T7/00
Filed: 1994-05-09
Abstract: PURPOSE:To provide an inspection method which enhances selectivity of a defective shape without complicating a hardware, and can conduct a process at a boundary part at a high speed even when a contrast between an uninspected area and an inspected area is large. CONSTITUTION:Image data in which a neighbourhood averaging process is convolution integration processed by a space filter in relation to picked up image data is division-processed in each corresponding picture element by image data in which masking image data expressed by a binarized image wherein every picture element in an inspected area is defined as 1 while every picture element in an uninspected area is defined as 0 is convolution integration processed. Accordingly, inspection including the outer peripheral part can be conducted at a high speed without changing a process for every change of an outer peripheral shape. Particularly, in the case where a brightness difference between the inspected area and the uninspected area of a sample is small, by applying a division-process with a specified constant for each picture element to neighbourhood averaging processed picked up image data, further simplification of a process can be achieved.
