Title: Chemical vapor growth apparatus and semiconductor growth method by means of said apparatus
Inventor: YAMAZAKI TATSUYA
IPC: H01L21/205
Filed: 1990-08-02
Abstract: PURPOSE:To prevent the transmission factor of a light-transmitting window from being lowered at a chemical vapor growth operation which utilizes a growth temperature reduction effect by irradiation with ultraviolet rays by providing a light source from which a wavelength component in a range capable of decomposing a semiconductor compound has been removed and which is installed so as to face one surface of a substrate. CONSTITUTION:To an apparatus which pyrolyzes a raw-material gas containing a semiconductor compound and which grows a semiconductor layer on a substrate 3, the following are provided: a reaction container 1 which houses the substrate 3 and into which the raw-material gas is introduced; a light source 4 from which a wavelength component in a range capable of decomposing the semiconductor compound is removed and which is arranged so as to face one surface of the substrate 3; and a means 21 to heat the substrate 3 up to a temperature at which the semiconductor compound can be decomposed on the surface of the substrate 3. For example, when a raw-material gas which is introduced into a reaction container 1 is Si2H6, an optical filter 7 which cuts off UV at 200nm or less is installed between a UV light source 4 and a UV irradiation window 6. Thereby, Si2H6 is not decomposed when it is irradiated with UV and it is decomposed only by a pyrolytic reaction on the surface of the substrate 3.

Abstract: PURPOSE:To prevent the penetration of dust into a cover, by respectively covering the upper and lower parts of a member to be vapor deposited with upper and lower covers and supplying air having pressure higher than that of air in the outside of the covers into the covers when air is supplied to and exhausted from the apparatus. CONSTITUTION:The member 19 to be vapor deposited in a vacuum container 11 is covered with upper and lower covers 22, 23. When a container 11 is evacuated by an exhaust port 13, clean air of a bomb 27 is supplied into the upper cover 23 by an air supply means 26. At this time, the variable fluid throttle valve 30 of a control means 29 is gradually throttled with the elapse of an exhaution time to gradually enhance the resistance of a flowline and the pressure of clean air to be supplied is always kept higher than that in the container 11. When the container 11 is returned to atmospheric pressure from vacuum by supplying air to said container 11 from an air supply port 12, the variable fluid throttle valve 30 is gradually loosened to gradually reduce the resistance of the flowline and the pressure of clean air is always kept so as to be made higher than that in the container 11. By this method, dust in the container 11 is prevented from adhering to the surface of the member 19 in a thin film form.

IPC: H05K3/34
Filed: 1992-08-03
Abstract: PURPOSE:To secure a soldering area on a pad without increasing the accuracy necessary for printing a solder resist and prevent a solder from bridging the pads, by so printing the solder resist that both its ends overlap with the pads respectively. CONSTITUTION:Pads 5a, 5b are formed on a printed-circuit board 3, and a solder resist 4 is so printed between the pads 5a, 5b that both the ends of the solder resist 4 overlap with the pads 5a, 5b respectively. A pad width m1 is made larger than a soldering width m0, and the spacing pitch of the pads and the printing width of the solder resist 4 are so designed as to be (p) and (n) respectively. Thereby, such effects are obtained that without increasing the accuracy necessary for printing the solder resist 4 it is printed easily k between the pads provided at the fine spacing pitch and that a soldering area on the pad is secured and a solder is prevented from bridging the pads. Further, since the height of the bank of the solder resist 4, whose two ends overlap with the pads respectively, is raised more highly than the surfaces of the pads, the effect of cutting off the solder is made large and the effect of preventing the solder from bridging the pads is further improved.
