Title: Semiconductor device and manufacture thereof
Inventor: NAKANO TOSHIO
IPC: H04N5/335
Filed: 1986-03-24
Abstract: PURPOSE:To improve reliability especially in organic sealing and to impart reliability to a device so as not to pose problems in practical use, in a semiconductor element, in which a semiconductor chip is mounted in an outer container such as a package, by including a gas adsorbent, which adsorbs intruded moisture due to water-vapor transmission and corrosive gas, in the package. CONSTITUTION:A gas absorbent is included in a package. Thus moisture caused by water vapor transmission is adsorbed. The increase in steam pressure in a cavity is delayed, and time for dew condensation is delayed. The gas adsorbent comprises Ag paste or Al paste. The amount of application is made to be 0.25mg/mm<2> or more. When structural irregularities are provided at a die attaching part, the filling amount can be remarkably increased. The gas adsorbent 9 is molded and hardened after total porous powder, e.g., silica gel or alumina gel, has been mixed into an organic resin. When the resin and the gas adsorbent are mixed, it is desirable to perform pressure reduced degassing or defoaming. The gas adsorbing powder can be dispersed and mixed in the resin or paste of Ag or Al. When balls of material such as glass are mixed in the Ag paste and the paste is applied, the thickness can be increased.

Abstract: PURPOSE:To enhance the reliability of a semiconductor device by forming a thin phosphorus glass layer at the lower part of the first layer aluminum in a multilayer wire formed on a thin oxidized film on the surface of a substrate and interposing a thick phosphorus glass at the lower part of a polyimide resin between the layers. CONSTITUTION:A multilayer aluminum wiring is formed with a polyimide resin 7 as an insulating layer in an MOS device in which a thin SiO2 film 2 is formed on the surface of a substrate 1. A thin (-100Angstrom ) photphorus-doped SiO2 film 6 is formed on the film 2 in this wiring structure, and the first layer aluminum 4 is formed on the top of the film 6. After a thick (-5,000Angstrom  or thicker) phosphorus  glass layer 8 is then accumulated on the overall surface, polyimide resin 7 is rotatably coated on the layer 8, and the second aluminum layer 10 is thereafter formed  on the resin. Thus, it can prevent the contamination from the first layer aluminum  and from the polyimide, thereby enhancing the reliability of a semiconductor device which applies a flattened multilayer wiring structure.
