Title: Method for formation of interconnection channel on semiconductor substrate and semiconductor device
Inventor: KUSHIYAOOCHIYAN MU
IPC: H01L23/522
Filed: 1993-06-29
Abstract: PURPOSE: To selectively deposit a second dielectric layer by permitting part of an interconnection channel to be located on a conductive plug, and making a first dielectric layer to stop etching. CONSTITUTION: First dielectric layers 22, 23 are deposited on a substrate and are patterned to form a contact opening 30. The opening 30 is filled with contact plugs 40, 41. A second dielectric layer 50 is deposited thereon and is patterned to form an interconnection channel 51. Therein, the first dielectric layers 22, 23 act as etching stopper for preventing the substrate from being etched. The dielectric layers are deposited on the substrate in such a manner, and are patterned to form the interconnection channel 51. Further, an interconnection part 61 is formed on the patterned dielectric 50 and in the interconnection channel 51. The interconnection part 61 may include a barrier layer 60 and a metal layer 61. Hereby, an interconnection part can be formed in a predetermined channel.

Title: Laser beam machine
Inventor: HAMADA SHIRO
IPC: B23K26/00
Filed: 1994-08-03
Abstract: PURPOSE:To prevent deviation of mask position resulting from change of a mask by giving mask alignment mark to a mask and correcting mask position while monitoring a mask through a dichroic mirror. CONSTITUTION:When a mask 43 is changed, the rear face of mask 43 is irradiated with an illuminating lamp 16. Reflecting light transmits a dichroic mirror 44 and makes the monitored picture of mask 43 on a camera 11-2. A mask alignment picture processor 12 calculates deviations in X axis, Y axis, theta direction based on the position of mark picture. The calculated values are received by a mask stage control part 13, which moves XY stage 15, theta stage 14 so as to correct deviations. A work 46 is irradiated with the laser beam from a laser oscillator 40 through the mask 43, laser beam machining is executed in high precision, thus a machined position precision of <=1mum is obtained.

Title: Burner for reducing nitrogen oxide
Inventor: MASAI TADAHISA
IPC: F23C99/00
Filed: 1986-08-05
Abstract: PURPOSE:To excellently constantly mixing after air with a waste gas thereby to accomplish reduction of NoX in a wide load range of the burner by dividing the supply of after-air into at least two parts, and supplying air independently to each after.air supply part. CONSTITUTION:Air whose pressure is raised by a force blower is heated by an air preheater, and is supplied to respective stages of window boxes of a front wall and a rear wall as combustion air components A3 and A4 to burn the fuel. In this case, the amount of combustion air supplied is made a theoretical air amount or less to carry out a low NOX operation. Residual air is supplied to an after-air supply part as after-air. In this case, the supply amount is adjusted on the basis of the load condition and the like of the boiler. In a case where the supply amount of after-air is large, both a first after-air supply part 14 and a second after-air supply part 15 are opened to supply air. When the amount of after.air supplied is small, after-air is supplied only from one cf the after-air supply parts, whereby lowering of draft of after-air is prevented, aud after-air is excellently mixed in the waste gas.

Title: Mos type transistor
Inventor: KURIYAMA HIROKO
IPC: H01L29/78
Filed: 1989-07-14
Abstract: PURPOSE:To suppress hot carriers by forming a partial well region by partly implanting impurity without forming a well region on a whole surface. CONSTITUTION:A P-type well region 2 is formed on a P-type silicon substrate 1 except a region formed with a channel. The surface of the substrate 1 is oxidized, a gate oxide film 3 is formed, and a gate electrode 4 is then formed. With the electrode 4 as a mask an N-type low concentration impurity diffused layer 5 is formed, and sidewalls are formed on the sidewalls of the electrode 4 and the film 3. In this case, since the low concentration impurity diffused layer under the sidewall is formed in the lower impurity concentration substrate than that of the well region, a depletion layer is extended larger to reduce an electric field smaller. Thus, generation of hot carriers can be suppressed.

IPC: B41J2/30
Filed: 1990-07-11
Abstract: PURPOSE:To prevent burnings of a switching element and a load coil by comparing a voltage to be applied to the load coil with an input signal. CONSTITUTION:An input IN1 and an input IN2 are both at 1 at non-driving time and are made to be at 0 at driving time, so that transistors TR1 and TR2 are both turned on and a coil L is energized. When the input IN1 is at 1, a collector of the transistor TR1 is almost an earth voltage so that 1 is given to one input of an exclusive-OR circuit EOR and 0 is given to other input and its output is at 1. Further, when the input IN1 is at 0, the collector of the transistor TR1 becomes almost a power +VD and a connecting point of a resistance R1 and a Zener diode ZD becomes a voltage which corresponds to 1, and the output of the exclusive-OR circuit EOR becomes 1 also at this time.
