Title: Formation of interconnections
IPC: H01L21/306
Filed: 1974-01-08
Abstract: 1434862 Semiconductor devices; printed circuits HITACHI Ltd 8 Jan 1974 [12 Jan 1973] 00876/74 Headings H1K and H1R In a semiconductor device, a conductive track, suitable for the lower track of a crossover structure, is formed from a conductive layer by oxidizing the layer surface, masking, and etching with an etchant which preferentially attacks the oxide to undercut the mask and produce a track having bevelled side edges. As shown, an aluminium layer 6b is vapour deposited on to a substrate 4 covered with a protective film 5, and is then oxidized, e.g. by anodization, using oxalic acid, or by thermal oxidization. The oxide 7b is masked using photoresist 8, and etched using, e.g. a mixture of phosphoric acid, acetic acid, water, ammonium fluoride and nitric acid, which removes the oxide at a rate two to three times greater than the aluminium, causing the track 6a to assume the shape shown. The bevel angle # is preferably between 20 and 40 degrees, and is controlled by the ratio between the thicknesses of oxide and aluminium. The mask and remaining oxide cap 7a are removed, and an insulating layer of SiO 2  or glass is deposited over the track and film 5, and a further conductive track is deposited to produce a crossover structure. Alternative materials for track 6a are titanium, tantalum, zirconium, chromium, niobium, molybdenum and silicon, and alloys thereof.

Abstract: A television system comprises a first input terminal (20) for providing a composite video (CSCC) signal or a separated luminance (SCC) signal, and a second input terminal (15) for providing a separated chrominance (C) signal. A change-over switch (11) has a first input (a) coupled to the first input terminal (20) through a path including a color sub-carrier filter (9), a second input (b) coupled to the second input terminal (15) through a path not including the color sub-carrier filter (9), and an output (c) coupled to the input (d) of a color decoder (8). The change-over switch couples the input (d) of the color decoder (8) to the first input terminal (20) in a first position (a), and couples the input (d) of the color decoder (8) to the second input terminal (15) in a second position (b). A sub-carrier detector (CK) is coupled to the output (c) of the change-over switch (11) for detecting the presence or absence of a color sub-carrier. A control unit initially causes the change-over switch ( 11) to be in the first position (a) and thereafter causes said change-over switch (11) to remain in the first position (a) if a color sub-carrier is present at the output (c) of the change-over switch (11), but causes the change-over switch (11) to be in the second position (b) if a color sub-carrier is not present. Once the change-over switch (11) is in the second position (b), the control unit (1) causes said change-over switch (11) to be switched back to said first position (a) from said second position (b) if a color sub-carrier is still not present.

Title: Semiconductor integrated circuit
Inventor: SHIRAKI HIROYUKI
IPC: H01L27/04
Filed: 1984-01-04
Abstract: PURPOSE:To obtain low resistance easily by forming a resistance region in a polycrystalline Si layer burying a groove element isolation region. CONSTITUTION:A groove element isolation region consists of an Si oxide film 3 constituting an inner wall surface and a polycrystalline Si oxide layer 4 burying the inside of a groove. A polycrystalline Si layer resistor forming region 5 is formed to a projecting shape so as to mutually superpose to a base region in a transistor. The value of a resistor R formed takes an extremely low value of 100OMEGA/mm.<2> because thickness in the vertical direction of the polycrystalline Si layer is sufficient at that time. However, a resistance region is isolated from other element regions only by the Si oxide film 3 in approximately 0.1mum thickness on the inner wall of the groove, but no problem is generated under the normal state of usage.
