Title: Flat display panel fabrication method
IPC: H01J11/10
Filed: 1976-08-17
Abstract: 1496755 Matrix displays INTERNATIONAL BUSINESS MACHINES CORP 17 Aug 1976 [17 Sept 1975] 34138/76 Heading G5C [Also in Division H1] To make a flat display, e.g. gas discharge, panel with two intersecting sets of parallel conductors lying on the same substrate with between them cells at the intersection filled with display medium, e.g. gas, an insulating preferably transparent substrate has formed on one surface a first set of parallel conductors also preferably transparent over which a spacer layer is laid down, having areas removable on treatment to form the cells and areas irremovable under the same treatment to form a series of supports side by side in the direction of the second set of parallel conductors which are laid down across the complete spacer layer: treatment is then applied to remove the removable spacer areas, leaving voids at the cells. The substrate 1 may be of glass coated with sputtered SnO 2  or (In 2 O 3 +SnO 2 ) etched with HCl or H 2 SO 4  into parallel conductor strips 2 the whole being then covered with sputtered SiO 2  dielectric 3. On the silica a spacer layer 4 of Al is vacuum deposited A and support areas 5 and frame areas 5<SP>1</SP>, 5<SP>11</SP> are anodized B through gaps in a photoresist over removable areas 6 (Fig. 2, not shown). A further SiO 2  dielectric layer 7 is applied C followed D by the transverse parallel conductors 8 of copper and a third E silica dielectric layer 9 (Fig. 3, not shown). The last two dielectric layers are removed by etching with HF or NH 4 F + HF, leaving the edges of conductors 8 protected by silica. The removable spacer areas 6 of Al can then be etched F with H 3 PO 4 +HNO 3 , or NaOH, possibly under ultrasonic vibration, leaving voids 12 at the intersections (Fig. 5, not shown). Finally the neighbouring or alternate ends of conductors 2 and 8 are exposed by etching the silica to allow connection, and a cover 13 is affixed by solder glass to the alumina frame 5<SP>1</SP>, 5<SP>11</SP>. Instead of deposition of the conductors 2 and 8 followed by etching in strips, the conductor layer may be of Al anodized completely in strips to form insulating separators possibly simultaneously with spacer areas 5, and/or the silica layers 3, 7,9 maybe replaced by superficial anodized layers. The spacer layer may be of metals such as Ta, Nb, Zr, Hf etched by HF, necessitating the use of, e.g. Al 2 O 3  e.g. by anodizing, or of Si 3 N 4  as dielectric. The conductors may also be made of the above metal, oxidizable on the surface to replace a separate dielectric layer. Either the substrate or the cover plate may be used for receiving the display.

Abstract: 287,892. La Corsa L. U. March 29, 1927, [Convention date]. Tin chloride, oxychloride, sulphate, and hydrate.-In detinning tin plated scrap by means of a solution of a ferric or stannic salt, the ferrous or stannous salt formed is regenerated by adding the anion of the used salt to the liquor, which may then be used to dissolve more tin, the solution and regeneration steps being repeated until a solution very rich in tin is obtained. For instance, when use is made of ferric or stannic chloride, the ferrous and stannous chlorides formed may be regenerated by passing chlorine gas through the liquor, or by adding a chlorine solution, or sodium or calcium hypochlorite and hydrochloric acid; and when ferric sulphate is used, sulphur dioxide and oxygen may be passed into the liquor in the presence of a catalyst such as nitrogen peroxide. Ammonium chloride or sulphate may be added to the solution prior to or after regeneration. Tin may be recovered from the solutions obtained by electrolysis, or be precipitated as oxychloride or hydrate by steam or air and oxygen, by ammonia, or by caustic alkali or carbonate.
