Patent number: 5497545Abstract: A multi-layer wiring assembly including a stack of insulating layers, e.g. of polyimide, alternating with wiring patterns, typically of copper. To establish the circuit pattern, successive wiring patterns are connected to one another through the intervening insulating layers at predetermined locations, by metal stud connections. The studs are formed during assembly of the stack by wire-bonding a stud onto an underlying wiring pattern through a through-hole of the insulating layer above, and then stamping the exposed end of the wire-bonded stud to spread it into contact with the uppermost wiring pattern. The wire-bonded studs e.g. of Au, form strong bonds with the underlying conductor and are quick to apply in an automated process using a wire-bonding machine.Type: GrantFiled: March 18, 1993Date of Patent: March 12, 1996Assignee: Hitachi, Ltd.Inventors: Ryuji Watanabe, Osamu Miura, Kunio Miyazaki, Yukio Ookoshi, Akio Takahashi

Patent number: 5175608Abstract: A thin film forming method and apparatus, wherein a negative voltage is applied alternately to a target and a substrate to perform film formation and reverse sputter alternately. Further, a coil is mounted between the target and the substrate and a high frequency current is made to flow therethrough to generate plasma. A negative base voltage smaller in absolute value than that during sputter may be applied to the substrate to make Ar ions flow into the substrate while it is subjected to reverse sputter. Thus, a film whose step coverage is 0.3 or more is possible. It becomes also possible to maintain a stable discharge and perform reverse sputter in a high vacuum region. The pressure of an Ar atmosphere may be lowered to 10.sup.-3 Torr or less.
