Abstract: PURPOSE:To make it possible to improve the film quality of a barrier metal at step sidewall part by vertically depositing an oxide film after forming barrier metal at an electrode window, and heat-treating it in the nitrogen gas containing a very small amount of oxygen gas. CONSTITUTION:An electrode window 13 is opened in a silicon oxide film 12 on a silicon substrate 11, and a TiN film 14 is accumulated as barrier metal. Next, by a vertical deposition method, a silicon oxide film 15 is accumulated. Thereafter, heat treatment is done in the nitrogen atmosphere containing 1-0.12% of oxygen gas at 480 deg.C for 30 minutes. By this heat treatment, it turns out that nitriding of Ti is accelerated, that the surface of the TiN film 14 at a step sidewall part is oxidized, and that oxygen is buried in linear faults, etc., inside the TiN film 14, and the film quality of the TiN film 14 at the step sidewall part improves. Also, by doing vertical deposition, protection from the flat part and the TiN film 15 at the groove bottom part in the electrode window 13 is performed, and only the step sidewall part is selectively oxidized.

IPC: B60B33/00
Filed: 1987-08-10
Abstract: PURPOSE:To facilitate step traveling without making the diameter of a wheel larger by providing a stopper member in the supporting shaft of a chassis, while rotatably supporting a camber member in freely contact with the stopper member on a fork rotatably supported by a supporting shaft so as to make the camber member slide up a step. CONSTITUTION:When a caster travels on a flat road surface 4, the bottom surface 3b of a camber member 3 pivotably supported together with a wheel 2c by the supporting shaft 2b of a fork 2 goes down to a lower limit position 3b by its dead weight and as well the top end 3c is drifted away from the groove 1c of a stopper member 1b provided in a chassis 1. As a result, the fork 2 can oscillate around the supporting shaft 1a of the chassis 1. On the other hand, when the caster approaches the step 4a, the camber member 3 rides on the step 4a so that the bottom surface 3b goes up from the lower limit position 3b' and the top end 3c is also brought into contact with the groove 1c. As a result, the bottom surface 3b of the camber member 3 slides up the step 4a while the wheel 2c advances floating.

Title: Liquid crystal display device and its formation
Inventor: FUJII MASAYUKI

Abstract: PROBLEM TO BE SOLVED: To make it possible to eliminate coloration in the case of observation from a specified direction and to obtain good display quality by providing opposite electrodes with projecting parts, locally diminishing the distance between the electrodes and forming these portions as strong electric field regions. SOLUTION: When the projecting parts 3a, 3b are formed at the opposite electrodes 1a, 1b and voltage is impressed thereto, the electric field intensity of the regions of the electric fields 6a, 6b short in the inter-electrode distance is higher than that of the region of the electric fields 6c, 6d long in the inter-electrode distance. The liquid crystal molecules 2a existing in the strong electric field region rotate to change the alignment to the electric field 6a and the liquid crystal molecules 2b to change the alignment to the electric field 6b, respectively.  The surrounding liquid crystal molecules are also dragged by these movements, by which the liquid crystal molecules 2c are rotated in the same direction as the direction of the liquid crystal molecules 2a and the liquid crystal molecules 2d are rotated in the same direction as the direction of the liquid crystal molecules 2b, respectively. Consequently, the rotating direction of the respective liquid crystal molecules may be changed in the region where the electric fields 6b, 6d are impressed and the regions where the electric fields 6a, 6c are impressed. As a result, the double refractivity of the liquid crystal molecules in both regions is eventually cancel with each other, by which the coloration at the time of observation from the specified direction is eliminated.
