Then please refer to Fig. 3 D, optionally dispose an adhesion layer 350 on the bottom surface 314 of substrate 310.Wherein, the time point that is configured the step of adhesion layer 350 is not limited to dispose after the line layer 320, but all can before to setting pointolite 330 (being illustrated in Fig. 3 E) after substrate 310 is provided.
Then please refer to Fig. 3 E, set a plurality of pointolites 330 on the bottom surface 314 of substrate 310.Wherein, the kind of pointolite 330 and equipping position are identical with the pointolite 230 of Fig. 2.In addition, pointolite 330 for example is to be fixed on the bottom surface 314 of substrate 310 by adhesion layer 350.
Then please refer to Fig. 3 F, pointolite 330 is electrically connected with line layer 320.Wherein, electric connection point light source 330 for example is that routing engages with the method for line layer 320.Certainly, also can adopt flip-chip bond or other proper technology to come electric connection point light source 330 and line layer 320.
Then please refer to Fig. 3 G, after setting line layer 320, also optionally cover an insulation course 360 on line layer 320.
Then please refer to Fig. 3 H, after finishing electric connection point light source 330 and line layer 320 at least, also optionally form a plurality of packing colloids 370 (only illustrating among Fig. 3 H) on the bottom surface 314 of substrate 310, and make packing colloid 370 cover pointolites 330 and with being electrically connected of line layer 320 (for example lead, projection (bump) ... or the like).The main effect of packing colloid 370 promptly be protection pointolite 330 and with being electrically connected of line layer 320.
For example, in the method that forms packing colloid 370, for example cover a mould (not illustrating) earlier on the bottom surface 314 of substrate 310, between mould and substrate 310, to form a plurality of die spaces, and these die spaces will form the position of packing colloid 370 videlicet, so pointolite 330 need be positioned at die space.Afterwards, insert a packaging adhesive material in each die space.Then, for example use baking or alternate manner cure package glue material, to form aforesaid packing colloid 370.The material of packing colloid 370 for example is epoxy resin (epoxy resin) or other suitable material.
Then please refer to Fig. 3 I, after forming packing colloid 370, also optionally dispose a reflecting piece 380 on the bottom surface 314 of substrate 310, and cover line layer 320 and packing colloid 370 with reflecting piece 380.The material of reflecting piece 380 for example is aluminium, silver, copper or other metal material, can certainly be the good material of any reflective.In addition, be good to keep kenel very close to each other between reflecting piece 380 and the packing colloid 370.For making reflecting piece 380 and packing colloid 370 driving fit mutually, also can when making reflecting piece 380, reserve the space that holds packing colloid 370 with for example impact briquetting or alternate manner earlier.So far, i.e. the roughly making of finished surface light supply apparatus 300.
In addition, though the reflecting piece 380 with full wafer is an example in Fig. 3 I, reflecting piece 380 also can a plurality of little reflecting piece (not illustrating) replaces, and little reflecting piece only need cover packing colloid 370 and gets final product.Perhaps, reflecting piece 380 also can a layer of reflective material (not illustrating) replace.Certainly, layer of reflective material can only cover packing colloid 370, or covers together with line layer 320.To arrange in pairs or groups diagram after a while and the replacement scheme of aforementioned various reflecting piece 380 will be introduced.
In addition, when not carrying out the formation of packing colloid 370 in the aforementioned step, also optionally after electric connection point light source 330 and line layer 320, dispose a reflecting piece (not illustrating) on the bottom surface 314 of substrate 310, line layer 320 and the pointolite 330 that do not cover packing colloid 370 are then between reflecting piece and substrate 310.Perhaps, also optionally form a layer of reflective material (not illustrating) to cover line layer 320.
Fig. 4 to Fig. 8 illustrates the part sectioned view into the planar light source device of five kinds of embodiment of the present invention.In the planar light source device of these five kinds of embodiment, main difference is the position of reflecting piece, the shape of packing colloid and three aspects such as design of substrate, and remainder is then identical with the explanation of Fig. 3 A～3I, will omit its introduction at this.
At first please refer to Fig. 4, planar light source device 400 is similar to the planar light source device 300 of Fig. 3 I, but does not illustrate as insulation course among Fig. 3 I 360 and adhesion layer 350.By among Fig. 4 as can be known, planar light source device 400 provides electric power with drive point light source 430 in when running by line layer 420.The light that pointolite 430 is sent can directly enter in the substrate 410, or via entering again in the substrate 410 after the reflection of reflecting piece 480.Simultaneously, the light that enters in the substrate 410 can spread the back by light-emitting area 412 ejaculations via substrate 410, or is directly penetrated by light-emitting area 412 without diffusion.By above-mentioned mechanism, the light that each pointolite 430 is sent promptly can be exchanged into high brightness and uniform surface light source, and is penetrated by the light-emitting area 412 of substrate 410.Certainly, on the light-emitting area 412 of substrate 410 also configurable for example diffusion sheet (diffusionfilm), prismatic lens (prism film), brightening piece ... wait all kinds of blooming pieces, to promote the brightness and the homogeneity of the area source that planar light source device 400 produced.
In addition, the profile of packing colloid 470 is example with the hemisphere in the present embodiment, but the profile of packing colloid 470 also can be cone, pyramid, warp suitably curved body or other suitable profile of curvature design.Certainly, the profile of packing colloid 470 with light utilization efficiency can be promoted to be up to good.In addition, reflecting piece 480 is an example to cover line layer 420 and packing colloid 470 in the present embodiment.
Then please refer to Fig. 5, planar light source device 500 is with the difference of the planar light source device 400 of Fig. 4, covers each packing colloid 570 respectively by a plurality of reflecting piece 580.Certainly reflecting piece 580 also can layer of reflective material replace, and the generation type of layer of reflective material for example is sputter (sputter) or other suitable mode.
