Abstract: PROBLEM TO BE SOLVED: To effectively prevent malfunction and a reduction in capability of highly integrated semiconductor elements with high ability of shielding stray light, by coating a light-absorption film having a specific light-absorption rate on the surfaces of metallic layers other than a top layer. SOLUTION: Above a pixel transistor 2 formed on the surface of a silicon substrate, a metallic wire layer 52 made of a material such as aluminum is formed so as to cover a source area 21 and a drain area 22 via a first interlayer insulation film 51. A light-absorption film 53 is provided on the surface of the metallic wire layer 52. A light-shielding layer 55 is provided on the surface of the metallic wire layer 52, which includes light-absorption film 53, via a second interlayer insulating film 54. The light-shielding layer 55 is composed of a metallic film made of a material such as aluminum and is integrally formed with an adjacent pixel part. And then, silicon nitride is coated as a reflection suppressing film on the light-absorption film 53 made of TiN so as to increase a light-absorbing rate to 90% or more.  Consequently, it is possible to prevent the occurrence of leakage current that is resulted from stray light transmitting the insulation layers formed between the metallic wire layers and so on.

Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to pool polarizing plates without substantially applying stress to a liquid crystal cell at the time of rework operation by sticking the polarizing plates coated with a tacky adhesive having characteristics to lose adhesive power by reacting to irradiation with electron beams or UV to the liquid crystal cell. SOLUTION: The polarizing plates coated with a tacky adhesive 2a having the characteristics to lose the adhesive power by reacting to the irradiation with the electron beams or UV are stuck to the liquid crystal cell. For example, in the case of the rework of the upper polarizing plate 1, the upper polarizing plate 1 is irradiated with the electron beam from its surface to bring the tacky adhesive 2a into reaction. The adhesive power at the boundary A between the upper polarizing plate 1 and the tacky adhesives 2A and the boundary B between the tacky adhesives 2a and the upper substrate 4 is lost.  In this case, the compsn. of the tacky adhesives 2a is designed in such a manner that the adhesive power of the tacky adhesives 2a, the upper polarizing plate 1 and the substrate 4 attains <=10g/cm, by which the simple peeling of the upper polarizing plate 1 is made possible even if the liquid crystal is not strongly pressed.

In this case, the ink-A (a) is applied to the outer periphery of the roller 3 through an ink-applying member 5a, so that the ink-A is transferred from the roller 3 to the ink ribbon 2. Thereafter, the operation is sequentially repeated, and the ink-A in the part 5 is completely used, after which the ink-B (b) is applied to the ribbon 2. At this moment, the operator can know that it is the time to replace the ink cassette.

Title: Coating method
Inventor: YASUHARA MASARU
IPC: B05D1/30
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To obtain good coating quality by adjusting the coating conditions so that the movement of a contact point of the lower surface of a coating liquid bridge formation part and the web with each other due to the degree of subatmospheric pressure applied to the lower surface of the liquid bridge formation part shows a specified value, in the method that comprises coating a web by using a slide bead coating apparatus. SOLUTION: In this method, the bead shape formed by a coating die 1 is generally classified into two kinds with respect to its lower surface shape. One kind of bead shape is that formed when a bead lower surface 6 leaves the front edge of a sliding surface 2 and forms a coating liquid bridge toward a dynamic contact point 8 on a web 4. The other kind of bead shape is that formed when another bead lower surface 7 leaves a static contact point 10 on a lip surface 3 and forms a coating liquid bridge toward another dynamic contact point 9 on the web 4. Each of these two kinds of bead shape is closely correlated with the degree of subatmospheric pressure applied to the bead lower surface 6 or 7.  In order to form stable beads, various coating conditions are adjusted so that the movement of each of the dynamic contact points 8 and 9 due to this degree of subatmospheric pressure is <=6μm/mmAq., to secure good coating quality.
