Inventor: KIN YONKAN
IPC: H01L21/28
Filed: 1998-11-05
Abstract: PROBLEM TO BE SOLVED: To minimize the deterioration of the electrical characteristic, by forming impurity regions which are located at the upper portion of a first region and on both side portions of a gate on the first region before reoxidizing a gate insulating film formed on the upper surface of each region. SOLUTION: A photoresist layer 47 is formed only on a second gate 45b and a gate insulating film 43, and by implanting nitrogen ions into a first region 41a by an inclined ion implantation method using the layer 47 as a mask, impurity regions 49 are formed on both side portions of a first gate 45a. Here, the nitrogen ion regions reoxidize the gate insulating film. As a result, a gate insulating film 43a present on both sides of the gate 45a is formed thinner than a gate insulating film 43b present on both sides of the gate 45b. This thickness difference contributes to minimizing the deterioration of the electrical characteristic of the film 43a present on both sides of the gate 45a.

Title: Magnetic recording medium
Inventor: ISHIGURO SHU
IPC: H01F1/06
Filed: 1986-12-30
Abstract: PURPOSE:To obtain a magnetic recording medium which can realize high-density recording and has excellent corrosion resistance and dispersibility by incorporating specific iron-aluminum magnetic powder and carbon black into a magnetic layer. CONSTITUTION:The iron-aluminum magnetic powder and the carbon black are incorporated into the magnetic layer. The Fe-Al magnetic powder in which the content of Al is specified to 0.5wt.%-20% with respect to Fe is used as the magnetic powder in this case. The magnetic powder, therefore, exhibits the high corrosion resistance intrinsic to the Fe-Al powder and has good dispersibility. The corrosion resistance and dispersibility are extremely poor if the content of Al is below 0.5% and the electromagnetic conversion characteristic is deteriorated if the content exceeds 20%. Since the carbon black having over 900m<2>/g BET and >=110ml/100g oil absorption is used, the specific surface resistance of the magnetic layer can be lowered and drop-out is decreased. The magnetic coating compd. has high stability and maintains the coatability without being deteriorated when a coating speed is increased. The high electromagnetic conversion characteristic is thus maintained.

Title: Manufacture of semiconductor device
Inventor: ISOBE AKIRA
IPC: H01L21/28
Filed: 1990-11-20
Abstract: PURPOSE:To prevent the generation of cracks in an alloy film for wiring, by instantaneously fusing an alloy film for wiring, after the alloy film for wiring on a scribe line part is previously eliminated. CONSTITUTION:After a poly silicon film 13 and a layer insulating film 12 are formed on a semiconductor substrate 11 on the surface of which an element is formed, a contact hole is opened, and a scribe line part is exposed by etching the film 12. An Al-Si alloy film 15 is stuck on the whole surface. The film 15 on the scribe line part 14 is eliminated, and an Al-Si alloy film 15a is left only on an LSI chip part. Lamp annealing is performed for several seconds at a temperature higher than the melting point of Al. As the result of this treatment, the film 15a reflows and turns to an Al-Si allay film 15b. The contact hole is filled with the film 15b, and a step-difference is formed between the LSI chip part and the scribe line part. Thereby contraction force generated in a cooling process is released by the scribe line part 14, and the generation of cracks can be prevented.

Title: Cleaning device for ink jet printer
Inventor: HANAOKA YUKIHIRO
IPC: B41J2/165
Filed: 1990-11-20
Abstract: PURPOSE:To eliminate re-adhesion of ink and alien substances to a nozzle by providing a cleaning roller made of foamed body that touches against the nozzle of an ink jet head. CONSTITUTION:As a carriage body 6 is moved to the nozzle cleaning position, a nozzle plate 5 of a head 4 comes in contact with a cleaning roller 1 and then the cleaning roller 1 starts the rolling over the surface of the nozzle plate 5. With the contact kept in the state as mentioned above, the carriage 6 is moved several times in reciprocation in the directions indicated with arrows A, and thereby alien substances such as paper dusts are removed while the ink adherent to the surface of the nozzle plate 5 is absorbed. The cleaning roller 1 is made of elastic foamed body, and is made capable of sticking fast constantly in stability to the nozzle plate 5 even though the amount of overlapping between the head 4 and the nozzle plate 5 varies. Therefore the ink is absorbed while the alien substances over the surface of the nozzle plate are collected with cells, each of which is in small diameter and is strong in capillary attraction because of being compressed as the roller is pressed against the nozzle plate 5.

Title: Method and apparatus for evaluating insulation property
Inventor: INOUE KAZUYUKI
IPC: G01N23/225
Filed: 1986-12-29
Abstract: PURPOSE:To enable evaluation of insulating property in the submicron order, by making a positively charged particle irradiate a sample contacting an electrode to which a negative voltage is applied to detect the amount of particles generated. CONSTITUTION:Positive ions released from an ion gun 1 are converged with a lens section 2 to irradiate a measuring part of an insulating sample 3. By irradiation with the positive ions, the ion irradiated part of the sample 3 is charged positively. As a result of the charging, secondary ions toward a detector 7 change in trajectory to reduce the detection of secondary ions. With such an arrangement, an electrode 4 with a negative voltage applied thereto is arranged near the ion irradiated part positively charged and hence, the relaxation of charging occurs between the ion irradiated part and the electrode 4. This eases the decrease in the intensity of negative secondary ions, thereby enabling measurement of hourly changes in the detected intensity of the secondary ions. Thus, the insulating property of the sample 3 can be evaluated by detecting a decrease level of the intensity of the secondary ions per unit time with an arithmetic unit 8.

Filed: 1987-12-16
Abstract: PURPOSE:To prevent the occurrence of the drip of toner by exposing only a part where the separation pawl of an image carrier abuts in case of supplying magnetic toner to a magnet roll through the image carrier when a transfer material is not supplied. CONSTITUTION:Four separation pawls 8 are arranged in the axial line direction of a photosensitive body 1 and LED arrays for exposing blank 4 are disposed in positions corresponding to the separation pawls. Therefore, the part where the separation pawl abuts is exposed in case of supplying the magnetic toner to a cleaning device through the photosensitive body if necessary when the transfer material is not supplied, and the toner is prevented from sticking to said part. Thus, the sticking of toner can be effectively prevented from dripping in a device or scattering in a device.
