The lower ends of the pair of vias that are individually connected to the vibrating piece mount electrodes and pass through the substrate are connected to a pair of outgoing electrodes extending from the pair of external connecting electrodes at the diagonal positions of the back surface to the back central side Respectively.
According to the package for a piezoelectric resonator, even if a thin substrate is used, since cracks are not easily generated and reliability can be ensured in a manufacturing process of a piezoelectric vibrator using the package, the package and the piezoelectric resonator Is obtained.
However, in the piezoelectric resonator package described in Patent Document 1, in the first embodiment shown in Figs. 1 (a) to 1 (c), a plurality of the above- The current flows through the external connection electrode 17c, the via 16, the
It is an object of the present invention to solve the problems described in the background art and to provide a method of manufacturing a semiconductor device which can mount various electronic parts such as a quartz oscillator on a surface of a substrate body so as to be sealed, Another object of the present invention is to provide a wiring substrate which does not cause a problem in the back electrode at the time of mounting on the main board, and a plurality of connection wiring boards for connecting a plurality of wiring boards.
In order to solve the above-described problems, the present invention is characterized in that, in the form of a plurality of interconnecting wiring boards in which a plurality of the wiring boards are bundled, a metal plating film is surely coated on the surface of the conductor exposed to the outside in each of the wiring boards And a plurality of back electrodes formed on the back surface of the substrate body of the wiring substrate after the individualization is separated from the respective sides of the back surface.
That is, the wiring board according to the present invention (claim 1) of the present invention comprises: a substrate body made of an insulating material and having a rectangular surface and a rear surface in plan view; a plurality of back surface electrodes formed on a back surface of the substrate body; And a via conductor which penetrates through the substrate main body and conducts between the plurality of back electrode and the frame-shaped conductor portion, wherein the plurality of the plurality of Wherein a part of the back surface is exposed between the back electrode and the respective sides of the back surface of the substrate main body and the pair of back electrodes cross each other on the back surface of the substrate main body And at least one or more convex wirings are formed between the first and second electrodes.
According to this configuration, since the plurality of back electrodes formed on the back surface of the substrate main body are formed apart from the respective sides of the back surface, when the solder used for mounting the main wiring board on a main board such as a printed board is solidified It is possible to alleviate the stress accompanying the tensile force generated in the step. Therefore, problems such as peeling of the outer peripheral side of the back electrode can be prevented from occurring.
At least one or more convex wirings are formed from the back electrode to a pair of sides crossing (orthogonal) to each other on the back surface of the substrate main body. For this reason, in the state of a plurality of connection wiring boards, in which a plurality of the wiring boards are arranged side by side along the vertical and horizontal directions, connection wirings formed of mutually convex wirings between adjacent wiring boards are provided on the back surface of each board body At least one or more of them are formed on the respective sides of the frame. Therefore, when the plating current is supplied to the plurality of wiring substrates, the plating current can flow along the longitudinal direction, the lateral direction, and the oblique direction of the plurality of wiring substrates. Therefore, it is possible to provide a wiring board which reliably covers a metal plating film which is required to be provided on the surface of the conductor portion exposed to the outside such as the back electrode, the frame-shaped conductor portion, and the mounting electrode formed on the surface of the substrate body .
The insulating material forming the substrate body is ceramic or resin. The ceramics include, for example, high-temperature sintered ceramics such as alumina, aluminum nitride, and mullite, or low-temperature sintered ceramics such as glass-ceramics, and the resin includes, for example, an epoxy resin.
Further, the substrate main body is composed of a single-layer ceramic layer or a single-layer resin layer. It should be noted that the substrate main body is constituted by a laminate of a plurality of ceramic layers or a plurality of resin layers, and between the layers, for example, for connecting the via conductors on the upper layer side and the via conductors on the lower layer side Or a wiring layer for swirling may be formed. For example, in the case of a substrate body formed by laminating a ceramic layer on a flat plate and a ceramic layer on a rectangular frame in a plan view, the surface of the substrate body has a quadrangular shape and a rectangular frame shape.
The frame-shaped conductor portion on the rectangular frame disposed on the front surface side of the substrate main body may be formed along the periphery of the surface of the metal frame or the insulating layer on the upper layer side (for example, the ceramic layer) And is a frame-shaped metallization layer formed on the surface (surface) of a frame body on a rectangular frame made of an insulating material (for example, a ceramic layer).
A plurality of mounting electrodes for mounting a quartz vibrator, a semiconductor element, and the like are formed on the surface of the substrate main body surrounded by the metal frame or the frame body forming the frame-like conductor portion, and the plurality of mounting electrodes The plurality of rear conductors are also individually conducted by the via conductors.
In addition, the back electrode may be, for example, one pair (two) arranged along a pair of opposing sides on the back surface of the substrate body, or a pair of And a total of three back electrodes formed separately for each of the remaining two corner portions.
When the plurality of convex wirings laid on the back electrode on the rear surface of the substrate main body extend toward a pair of mutually adjacent pairs of the convex wirings adjacent to each other with at least a corner therebetween The bases are connected to the back electrode immediately without crossing each other.
The convex wirings may be formed in a shape that extends in a straight line and in an oblique direction as well as a shape that extends in a direction perpendicular to and straight to the side closest to the back surface of the substrate main body, And a shape in which the tip is extended at a right angle to the side.
Incidentally, the thickness of the back electrode and the convex wiring is in the range of about 10 to 50 mu m, and the width of the convex wiring is in the range of about 10 to 300 mu m.
In the present invention, it is preferable that the plurality of back-surface electrodes are formed at four corners of the back surface of the substrate main body, and each back-surface electrode has a pair of opposing sides And a wiring board (claim 2) in which at least one of the convex wirings is formed.
According to this configuration, at least one convex wiring is formed between the four back electrodes formed on the back surface of the substrate main body and a pair of respective sides crossing (orthogonal) to each other on the back surface. Therefore, in the state of a plurality of connection wiring boards to be described later, connection wirings formed of mutually convex wirings between adjacent wiring boards are provided on at least two sides Respectively. As a result, when the plating current is supplied to each of the plurality of wiring boards, the plating current stably flows along the longitudinal direction, the lateral direction, and the oblique direction of the plurality of wiring boards. It is possible to provide a wiring board on which a metal plating film is more reliably covered.
In addition, when the plating current is supplied to each of a plurality of wiring boards, the plating current flows in a plurality of directions (longitudinal direction, lateral direction and oblique direction in plan view) between the plurality of wiring boards, The thickness of the metal plating film coated on the surface of the back electrode or the like exposed to the outside can be made uniform. Further, since the plating current flows along a plurality of directions (energizing paths), for example, even when one path among these plural energizing paths is disconnected, the surface of the back electrode or the like exposed to the outside The metal plating film can be surely covered.
In the present invention, a plurality of mounting electrodes are formed on the surface of the substrate main body surrounded by the frame-shaped conductor portion in a plan view, and also between the plurality of mounting electrodes and the plurality of back surface electrodes, And a wiring board which is electrically conducted individually by via conductors passing through the via conductors.
Accordingly, in the state of a plurality of connection wiring boards to be described later, since a plating current flows through a plurality of mounting electrodes via a back electrode and a via conductor, a metal plating film is surely formed on the surface of each mounting electrode Respectively.
On the other hand, a plurality of interconnecting wiring boards according to the present invention (claim 3) according to the present invention comprises: a product area formed by arranging a plurality of the wiring boards adjacent to each other along the vertical and horizontal directions in plan view; And a plurality of plating electrodes formed on the periphery of the ear portion, the plating electrode being formed on the peripheral side of the product region, And a pair of wiring boards adjacent to each other with a boundary therebetween in the product area, the wiring board having a pair of wiring boards And is electrically connected via a connection wiring extending over the boundary.
According to this arrangement, when an electrode or the like is brought into contact with the electrode for plating on the opposite side of the opposite side of the ear portion, the plating current flows through the plating wiring and the connection wiring, The back electrode, the connection wiring, and the plating wiring on the opposite side, and then flows to the plating electrode on the other opposite side in the above-mentioned ear portion. Alternatively, the plating current may flow from the back electrode for each wiring board in the product area via the plating wiring and the connection wiring to another backside electrode, the connection wiring, and the adjacent wiring board through the via conductor and the frame- Back electrode, etc., and the plating wiring on the opposite side, and then flows to the electrode for plating on the other opposite side in the above-mentioned ear portion. At this time, the plating current surely flows between the backside electrodes of each of the plurality of wiring boards, which are vertically and horizontally adjacent to each other in the product area, in the longitudinal direction, the transverse direction and the oblique direction via the connection wiring. Therefore, in the individual wiring boards, a plurality of connecting wiring boards, for example, a metal plating film such as Ni and Au reliably covered on the surface of the back electrode or the frame-like conductor portion exposed to the outside .
The plating electrode formed on each side of the ear portions of the plurality of connection wiring boards is a semicylindrical conductor portion formed along the inner wall face of the recessed fan recessed groove in a semicircular shape when viewed from the top.
The plating wiring formed on the ear portions of the plurality of connection wiring boards may include a plurality of wiring electrodes formed on the plating electrode and a plurality of wiring boards located on the peripheral side of the product region adjacent to the sides of the ear portions on which the plating electrodes are located, Extending from the plating electrode to each of the front ends of the plurality of wirings or extending along the sides of the back surface of the plurality of wirings to connect the front ends of the plurality of convex wirings extending from the plating electrode A root line portion extending from the main line portion to the plating electrode and a plurality of branch line portions extending from the main line portion to each of the ends of the plurality of convex wirings are included have.
The present invention also includes a plurality of connecting wiring boards (claim 4) in which grid-shaped dividing grooves are formed in a plan view along the boundary dividing a plurality of wiring boards on the surface side of the product area do.
According to this, for example, when the substrate main body is made of ceramic, a plurality of the wiring boards can be easily and accurately obtained by applying a shearing force along the dividing grooves.
In addition, the boundary is an imaginary line (vertical plane) that divides the wiring boards adjacent to each other in a plan view, and the entire boundary shows a lattice frame shape in plan view.
In addition, the dividing groove includes a form showing a U-shaped cross section by laser machining or a form showing a V-shaped cross section by insertion of a blade.
Further, when the connection wirings connecting the backside electrodes of the two wiring boards adjacent to each other with the boundary therebetween are formed along the division grooves, the connection wirings become the convex wirings.
Incidentally, the dividing groove may be formed by inserting the blade at a predetermined depth from the surface side of the boundary, even if the board body and the ear portion of each wiring board are made of resin.
