摘要:
A cover member of an illuminating unit is formed of a film insert molded product, in which a film is disposed on a decorative face. The film is arranged so an end part of the film is positioned in front of an end part of the decorative face, whereby a film end protecting area formed of an exposed part of a molded resin layer is provided between the end part of the decorative face and the end part of the film, and a surface of the film end protecting area is made flush with the surface of the film. A corner between the end part of the decorative face and an end face of the molded resin layer is set to be an acute angle, and the end face of the molded resin layer functions as a contact face with respect to a ceiling trim.

The present invention provides a method for forming a siliceous film. According to the method, a siliceous film having a hydrophilic surface can be formed from a polysilazane compound at a low temperature. In the method, a composition containing a polysilazane compound and a silica-conversion reaction accelerator is applied on a substrate surface to form a polysilazane film, and then a polysilazane film-treatment solution is applied thereon so that the polysilazane compound can be converted into a siliceous film at 300° C. or less. The polysilazane film-treatment solution contains a solvent, hydrogen peroxide and an alcohol.

The present invention provides a siliceous film-forming composition having such a small thickness shrinkage ratio that a highly homogeneous siliceous film can be obtained. The invention also provides a trench isolation structure-fabrication process. According to this process, trenches even having very small widths can be homogeneously filled in. The composition contains a solvent and a polysilazane compound obtained by co-ammonolysis of one or a combination of two or more halosilane compounds. The process comprises the steps of coating a surface of a silicon substrate with the above composition, and subjecting the coated substrate to heat-treatment at less than 1000° C. under an oxygen atmosphere or an oxidizing atmosphere containing water vapor, so that the composition is converted into silicon dioxide in the form of a film.

The present invention provides a method for formation of a siliceous film containing nitrogen in a low concentration. The method according to the present invention comprises the steps of: applying a polysilazane composition on an engraved substrate surface, to form a coating layer; hardening the coating layer only in the part adjacent to the substrate surface, to form a covering film along the shape of the engraved substrate; and removing the polysilazane composition of the coating layer in the part not hardened in the above covering film-formation step. According to this method, two or more siliceous films can be formed and layered.

In order to provide an improved hybrid IC having a high density, compact in size, capable of being manufactured with a reduced cost, a hybrid IC of the present invention, comprises: a circuit board 2 having formed on the surface thereof a plurality of electrode patterns, and mounting on the same surface a plurality of electronic elements 3; a plurality of connection terminals 4 each formed into a generally rectangular frame structure including mutually facing first and second lateral plates, and mutually facing first and second longitudinal plates. In particular, one of the first and second lateral plates of each connection terminal 4 is fixedly connected to a connection electrode 2a on the circuit board 2. With the use of such structure, it is allowed to dispense with a process of solely connecting the connection terminals, thereby reducing the time and hence the cost for manufacturing a hybrid IC. Further, it is allowed to connect only necessary connection terminals in optionally selected positions, thus avoiding additional cost which is unavoidable in a prior art. Moreover, it is possible to increase the freedom in the designing of a hybrid IC, rendering it possible to produce a hybrid IC which is compact in size, light in weight, and has a high density.
