Title: Complementary type field effect transistor
Inventor: MAEDA ATSUSHI
IPC: H01L27/08
Filed: 1987-08-27
Abstract: PURPOSE:To increase the driving capability of drain currents by forming an LDD structure using an oxide film as a mask in an NMOS, and forming a full gate structure wherein the oxide film is not used as a mask in a PMOS but an impurity diffusion layer is diffused right below a gate electrode. CONSTITUTION:Spacers 14a aud 14b, consisting of silicon oxide films which cover the slant surfaces of trapezoidal gate electrodes 11a and 11b, are formed. By ion-implanting an Ntype impurity such as using the Oxide film spacer 14a as a mask, an N<+> layer 15 of high concentration is formed. By this operation, an LDD structure wherein the N<+> layer 15 and an N<-> layer 12 have an offset area where respective diffusion areas are offset by the thickness of the oxide film spacer 14a. Then an impurity such as boron is ion-implanted to form a P<+> layer 16 within a substrate 1. At this point, the oxide film spacer 14b does not serve as a mask with respect to a boron ion, and therefore, the P<+> layer 16 is formed in such a way as pinching the gate electrode 11b from both sides as well as extending under the oxide film spacer 14b, whereby a so-called full gate type PMOS structure is formed.

Title: Array type angle beam probe
Inventor: HAGIWARA AKIRA
IPC: G01N29/24
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To surely detect a flaw inclined in any direction by aligning multiple vibrators with a convex curvature in the longitudinal and horizontal directions, independently controlling the delay time of transmission and reception of the vibrators, and deflecting ultrasonic waves in the desired direction. SOLUTION: When the delay time of the transmission pulses of vibrators 1 is linearly controlled by a longitudinal line direction delay time control device and a horizontal line direction delay time control device, the ultrasonic waves transmitted from the vibrators 1 are synthesized and can be deflected in the plate thickness direction and the welding line direction. Since the vibrators 1 are formed into a convex shape, the cylindrical sound field is formed, and the ultrasonic waves are spread in a wider range than in the past. The convex- shaped vibrators 1 are aligned in the longitudinal and horizontal directions, and the delay time of the transmission and reception of the vibrators 1 is independently controlled.  The ultrasonic waves can be freely deflected in a wide range in the plate thickness direction and in the welding line direction, and a flaw inclined in any direction can be accurately detected.

Title: Underwater plasma torch
Inventor: KATOU YOSHIHISA
IPC: B23K9/29
Filed: 1982-12-06
Abstract: PURPOSE:To eliminate the need for supplying separately cooling water from the other place without requiring a pump, etc. for feeding the cooling water by sucking the peripheral water by the negative pressure generated during ejection of gas for plasma, and discharging the same from the tip. CONSTITUTION:A plasma arc 18 is generated when gas for plasma is supplied in an arrow A direction in a gas feed member 12 and electricity is supplied to an electrode 16. The gas fed into the member has a larger flow rate hence higher dynamic pressure is generated as the sectional area of the passage is narrowed and throttled by an ejection port 26. The static pressure around the gap 27 near the ejection port decreases accordingly, thus generating a negative pressure. Since an underwater plasma torch is kept immersed in water, the water around the suction hole 28 is sucked therein and arrives at the gap 27 part, from which the water is carried by the ejection flow of the gas emitting from the port 26 and is ejected through a hole 22, then it is returned into the original water. The member 12, a ceramic plate 24 and a body 10 are thus cooled and the overheating thereof is prevented.

Filed: 1990-08-14
Abstract: PURPOSE:To improve the workability and the compatibility by providing a delay circuit adjusting a timing of A/D converter or the like and a monitor monitoring a picture synchronously with a delay picture element frequency signal to the processing unit, controlling a delay time while monitoring the picture and matching the timing to an optimum timing. CONSTITUTION:A pixel clock generating circuit 11 generates a pixel clock signal corresponding to a period of a vertical synchronizing signal VD and a horizontal synchronizing signal HD. Each delay circuit 12 gives a pixel clock signal delayed by 1nS each with a delay line 13 to a selector 14. An A/D converter 1 implements A/D conversion synchronously with the pixel clock signal delayed by 1nS. Then a digital color signal whose synchronization is delayed by 1nS is transmitted to the monitor system III. D/A conversion is implemented similarly in the monitor system III and a picture is displayed on a display device 24. Thus, the presence of picture disturbance is monitored and a selector 14 is switchingly driven by a controller 6 when any disturbance is in existence.

Title: Manufacture of semiconductor device
Inventor: WATABE KIYOSHI
IPC: H01L21/28
Filed: 1984-10-13
Abstract: PURPOSE:To prevent the deformation of a pattern, by dividing the forming process of an Al layer, which is provided on an insulating layer wherein a window is provided, into two stages. CONSTITUTION:An Al layer, which is formed on an insulating layer 2 wherein a window part 7 is formed, requires a thickness of about 1mum. The first Al layer 9 is formed so as to have a very thin thickness, e.g., a thickness of 1,000Angstrom . Under this state, heat treatment is performed under the same conditions, which will be applied in a later insulation coating process. By this heat treatment, a platinum silicide layer 3 and the first Al layer 9 are reacted and an alloy layer 5 is formed. The second Al layer 10 is formed on the entire surface of the layer 9. At this time, the thickness of the second Al layer 10 is made to be the remaining value of the thickness of the Al layer that is to be formed on the insulating layer 2, e.g., 9,000Angstrom . The alloy layer 5, which is formed in the insulation coating process, is provided by the heat treatment beforehand. Then the alloy layer is not grown furthermore. Therefore, deformation and wire breakdown of a conductor pattern, which is formed by selective etching, do not occur. Thus reliability of the semiconductor devices can be improved.
