A semiconductor device includes a plurality of wiring lines which are provided on an upper side of a semiconductor substrate and which have connection pad portions, and columnar electrodes are provided on the connection pad portions of the wiring lines. A first sealing film is provided around the columnar electrodes on the upper side of the semiconductor substrate and on the wiring lines. A second sealing film is provided on the first sealing film. The first sealing film is made of a resin in which fillers are not mixed, and the second sealing film is made of a material in which fillers are mixed in a resin.

A low dielectric constant film/wiring line stack structure made up of a stack of low dielectric constant films and wiring lines is provided in a region on the upper surface of the semiconductor substrate except for the peripheral part of this surface. The peripheral side surface of the low dielectric constant film/wiring line stack structure is covered with a sealing film. This provides a structure in which the low dielectric constant films do not easily come off. In this case, a lower protective film is provided on the lower surface of a silicon substrate to protect this lower surface against cracks.

In a method of manufacturing an ink-jet printer which uses a thin film sheet having adhesive layers respectively formed on the top and bottom sides, as an orifice plate, orifices are formed in the ink-ejecting side of the thin film sheet after the adhesive layer on that ink-ejecting side has been removed. This prevents the formation of the orifices from being adversely affected by any otherwise residual of the adhesive layer and can thus permit accurate formation of orifices of a desired shape. Even if helicon-wave dry etching which ensure fast etching using high-power energy is used to form orifices, therefore, no adhesive layer is thermally expanded to be a residual so that multiple orifices can be formed simultaneously and quickly.

An end separating device for a sheet having a backing paper, which can easily separate a film of the sheet from the backing paper without requiring half cutting of the sheet. A fixing and separating member is fixed to a movable blade of a cutter for cutting a tape, and another fixing and separating member is fixed to a fixed blade of the cutter. These fixing and separating members and cooperate to bend and fix a cut end portion of the tape. Accordingly, the cut end portion of the tape is bent. After the tape is released from the fixing and separating members, a film tape is elastically returned to an original condition owing to its relatively large stiffness, but a backing paper is plastically deformed at the bent portion. As a result, the film tape can be separated from the backing paper. In other embodiments of an end separating device, a separating member is passed along end surfaces of free end portions of the sheet. The separating member bends the end surfaces to plastically deform the backing paper and enable separation of the backing paper.

A ribbon driving mechanism for a typewriter, having a cam member provided on one side thereof with a first cam section for effecting control of a printing ribbon, and a second cam section extending continuously from the first cam section for effecting control of a correction tape, and a stopping member for controlling the movement of a cam follower along the cam sections. Either the printing ribbon or the correction tape is moved selectively to the printing position and only the rotation of a motor for driving the cam member in one particular direction, is transmitted to a printing ribbon winding mechanism, to wind the printing ribbon.

A printer head substrate having a silicon substrate on which heat generating elements and partitions are formed and an orifice plate which adhered to the partitions is placed on a stage of a helicon-wave dry etching system. Helicon-wave dry etching is performed while cooling the printer head substrate by allowing a coolant gas to be intervened between the substrate and the stage. This allows multiple orifices of a desired and adequate shape to be simultaneously and quickly bored in the orifice plate even if a thin film sheet having adhesive layers adhered to both sides thereof is used as the orifice plate, thereby improving the working efficiency.

A tape cutting device includes a fixed blade fixed to a frame and a movable blade fixed to a manually pivotable lever. A printing operation to the print tape is performed by a print head and a platen. In this case, the tape runs by the rotation of the press roller and a tape feed roller, those being driven by a driving motor 2 through a power transmitting portion including a gear train. A gear of the gear train is associated with a tape cutting prevention mechanism including a stop lever. When the tape printing operation is carried out, the stop lever is movable to a first pivot position where the manually pivotable lever is abuttable on the stop lever to prevent the manually pivotable lever to be angularly rotated. When the tape is to be cut, the stop lever is moved to a second pivot position offset from the manually pivotable lever. Thus, the movable blade can be moved toward the fixed blade to cut the tape.
