Abstract: PURPOSE:To prevent the increase of wiring resistance and the reduction of current capacity by forming Cu.Al compound layers onto the side surface and upper surface of a Cu wiring disposed between a first insulating film and a second insulating film. CONSTITUTION: A Cu wiring 3, the surface, a side surface and an upper surface, of which have a Cu.Al compound layer 5 having a CuxAly composition mainly comprising Cu and which consists of a single composition, is arranged onto a first insulating film (layer insulating film) 2 composed of a substance such as SiO2 shaped through vapor growth onto a semiconductor substrate 1 to which an element and a lower layer wiring, etc. are formed, and a second insulating film (coating insulating film) 4 made up of a PSG film, etc., through vapor growth is difficult to be formed onto a wiring forming surface. Since the surface of the Cu wiring having the single composition is coated with the Cu.Al compound layer shaped by contact heating with an Al layer, the surface of the Cu wiring is inactivated chemically, thus inhibiting the oxidation corrosion of the Cu wiring due to long-term heat history in case of the use of a semiconductor device and at a time when the vapor-growth insulating film is formed onto the wiring forming surface, then preventing performance degradation, such as the increase of wiring resistance, the reduction of current capacity, etc.

Title: High-temperature resin composition
Inventor: FUKUYAMA SHUNICHI
IPC: H01L21/312
Filed: 1986-06-09
Abstract: PURPOSE:To form a flat insulating layer having no crack and pin hole in spite of thick thickness by shaping the insulating layer by using an silicon polymer containing phosphorus. CONSTITUTION:An insulating layer is shaped onto a substrate including a stepped section generated by the formation of a wiring pattern by employing an silicon polymer shaped and acquired by copolymerizing dichlorosilane, trichlorosilane and dichlorophosphoric acid. A PSG film is proper as the insulating layer because it has flexibility besides high insulation resistance and cracks, etc.,are not generated, and cracks, etc., are not generated because phosphorus is substituted and contained in the network structure of silicon and oxygen. Consequently, the silicon polymer coupled with an silicon compound in the form of polyphosphoric acid is employed. Since the resin has a fluib temperature of 250-350 deg.C besides high insulation resistance, pin holes by a volatile curing reaction product and a thermal decomposition product generated at the time of curing are buried and strain can be removed when the resin is thermoset at a temperature of 350-400 deg.C.
