A method for encapsulating a molded portion (m() inging her (10)) of a light-emitting chip. 1 to 3 are views showing a conventional manufacturing method of a wafer-type light-emitting diode. FIG. 1(a) and FIG. 2(a) are plan views, and FIG. 1(1) is a cross-sectional view taken at l=(b), and FIG. 3 is a perspective view showing a conventional wafer type light emitting diode. The illuminating light 35 is mounted on, for example, a printed circuit board or a lead r. The substrate U has a lead electrode diagram '2 and the wafer is electrically connected to the lead electrode via the wire 13. The substrate U of the mold photocrystal I12 is positioned to form the molded portion 14. f knowing the forming process to the groove (_er), and illuminating: two: system:: flowable flow separation substrate η to obtain; slice two: formation. Then 'by sawing process according to the prior art, the individual light-emitting diodes are excellent. The hunting is performed by using the forming process 1307976 21726pif = to produce a wafer type light emitting diode, and the material having a large specific gravity (such as an inorganic optical body) can be uniformly dispersed in the molding portion 14 . The scooping is because the molded portion for encapsulating the luminescent wafer 12 is permeable to the light emitted from the self-illuminating wafer 12 via the molding portion U = (4). Therefore, the disadvantage is that the direction angle of the light is in the range of the desired direction angle _ the illuminating intensity is reduced, and the light of the moonlight is not increased, resulting in a greater loss of light. Further, since the surface of the cut surface on both sides and the molded portion as shown in Fig. 3 are also coextensive, the disadvantage is that the second portion cannot be formed on the cut surface of the molded portion 14. . At the same time, the knives are used to improve the illuminance in the desired range, and the reflection illuminator is used in the manufacturing method. The towel reflector is formed on the substrate or formed by injection molding an opaque synthetic resin. The reflective portion is then formed and then the transparent molded portion is formed in the reflector. The advantages of the method of manufacturing the reflector type light-emitting diode are to improve the direction of the direction angle (10). (9) Since the transparent molding portion is formed by the transfer molding process, it is generally used to observe the liquid resin to the reflection H _ method. Since the liquid resin is separately poured into the respective reflectors in the process of the granular (tetra) resin, productivity is lowered. Further, since it takes a lot of time to perform the molding process so that the phosphor having a large specific gravity sinks, it is difficult to provide a molded portion in which the scale body is uniformly dispersed. Moreover, the technique of attaching a reflector or using an emitter to form a reflector has a limitation of reducing the thickness of each of the light emitting diodes. SUMMARY OF THE INVENTION & ΜΛΜ. The manufacturing method of the light-emitting diode 'where the package is _ zone_. , the manufacturing method of the cut-off light-emitting diode of the substrate, the hair-molding part: the symmetry on the side surface of the drawn part, the second more advanced step is to provide a degrading light-emitting diode The method of coating t can prevent the thickness of the light-emitting diode from increasing. In order to solve the technical problem, the manufacturing method according to the present invention includes the step of preparing a substrate. The material will be placed on the middle mosquito (10) substrate. The intermediate plate has a through hole for receiving the hair piece and a groove for the through hole at the upper surface of the μ board. Next, a transfer molding process is performed with the transparent molding material by using the groove as a launder to form a first molded portion filling the through hole. Thereafter, the intermediate plate is removed and the substrate is separated into individual light-emitting diodes. Therefore, the first molded portion is formed in the through hole of the intermediate plate, so that it is possible to provide the light-emitting diode in which the first molded portion is positioned in the region surrounded by the cut surface of the substrate. 1307976 21726pif At the same time, the transparent molding material may contain scale powder. Therefore, the first molding is performed by using a transparent molding material containing a light filling material, thereby preventing the light body from sinking and positioning the intermediate plate on the substrate_1 before mounting the light emitting wafer. The luminescent wafer is mounted in a through hole of the intermediate plate. Meanwhile, in the embodiment of the present invention, after removing the intermediate plate, a second mold for surrounding at least a side surface of the first molded portion may be formed, in some embodiments of the present invention, by performing Molded to cover the first molded portion and formed by the second = until the upper surface of the first molded portion is exposed. Alternatively, the erroneous (four) non-permeable material may be entangled to fill the first ==fine septum and expose the upper surface of the first molded portion to form a second U-knife. The second molded portion formed of the opaque molding material can serve as a desired rib of the reflection direction angle, and the second molded portion is formed to be flush with the first molded portion, and has a Ρ square stop light emitting diode The increase in thickness. U. In this embodiment, a transparent molding material having a lens portion for covering the surface of the mold wtm can be used. The lens portion is used for focusing on the direction angle == 曰曰1 light' to improve the luminous intensity. The second portion of the f-part surrounding the at least side surface of the first molding portion is spaced apart from each other by the first mold Lt. Further, the second molded portion may cover, coat, and contain the phosphor. Therefore, it is possible to provide a light-emitting diode in which the second molded portion containing the phosphor is uniformly formed on the first molded portion. The second molded portion can be formed by using another intermediate plate having a through hole for receiving the second molded portion. A method of fabricating a light-emitting diode according to another aspect of the present invention includes the step of preparing a substrate. The luminescent wafer is mounted on the substrate and a first transparent molded portion for covering the respective luminescent wafers is formed. Next, a second opaque molded portion for the side surface of the if-mold portion is formed, and the earth plate is separated into individual light-emitting diodes. Therefore, the thickness is increased and the direction angle can be improved to prevent the diode from being removed. The illuminating of the radiance of the ray can be performed by performing the modulo f division with the opaque molding material and by removing the surface of the drawing portion after the opaque cover is removed; ^ Material is used to perform molding to fill the first: the wrong surface is formed by using the upper surface of the opaque mold-molded portion: the paste is separated and the advantageous effect is exposed.苐-====The formation process of the transfer molding process = the first molded part; the surface:: surrounded by the first diode. Therefore, the second mode (4) is a two-part molded part: having a lens portion, whereby the modified side: == becomes a reflection intensity. If the illuminating diode in the desired range having the angle of reflection is selected to be reversed, it is possible to increase the illuminating intensity in the acoustic target circumference with the thickness of the tester = the thickness of the diode. 0 1307976 21726pif [Embodiment] The embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following examples are provided to fully convey the spirit of the present invention to the skilled person. Therefore, the invention is not limited to the following but may be embodied in various different forms. For the convenience of the drawings, the width, length and thickness of the components are indicated in an exaggerated manner: In the specification, the same reference numerals are used to refer to the same elements. FIG. 9 is a plan view illustrating a light emitting diode according to an embodiment of the present invention and FIG. 8(a), and FIGS. 4(b), 5(b), J) and FIG. 8(b) are cross-sectional views. The frame is mounted on a substrate 31 such as a printed circuit board or a lead-free wood. As shown in the figure, the light-emitting crystal 32 32 is connected by a line 33 to the mother of the lead-light i-emitting wafer %. The single bond die may be a single bond die, wherein each of the wires 33 is limited to this. The light emitting chip 32 may be a double bond ^ ^ ^ - the middle wire 33 is separately bonded to the two electrodes, or The flip chip of the lead electrode electrically connected to the substrate without using m3. The photo of the second interposer 41 is positioned on which the light emitting chip 32 is mounted. The 3 plate 41 has a function for separately receiving the light. The through holes 44 of the wafer 32 and the recesses 43 between the intermediate plates 41. Therefore, the light-emitting wafers are each located in the through-holes of the intermediate plate 41. 11 1307976 21726pif Door 2: The material is Unlimited 'as long as the through hole 44 is shown in the form of a rectangular column in the transfer forming process, various shapes such as a truncated cone or a cone are taken. The grooves 43 may be connected to the through holes 44 in a row, but are not limited thereto, but may be connected in various forms. The sheet 32 is mounted with a light-emitting crystal plate 3 尽 before the intermediate plate 41 is mounted. After the intermediate plate 41 is positioned on the substrate, the luminescent wafer 32 can be mounted in the through hole 44. The substrate 31 is positioned between the lower mold 51 and the upper mold 53, for example, the groove 43 is used as a flow channel. The transparent molding material (for example, molding resin) performs a transfer molding process, 11 which forms a first manufacturing method of the first and right optical body, and the upper mold 53 may not have a material along the intermediate plate 41'. The recess 43 flows on the intermediate plate 41, thereby filling the hole 44. Thereafter, the transparent molding material is cured to form a first molded portion of 34 carcass. The molding material may contain a diffusing agent Uiffusingagent or fill The light-on-wire process forms the first-difficult portion 34, and thus the formation of the light-precursor precursor such as the light-emitting body 32 is "distributed" from the Τ mold 51 and the upper portion. The mold 53 takes out the sorrow of the soil plate. The intermediate plate 41 is still positioned on the substrate 31, and the intermediate plate 12

The remaining molded portion 34a is also filled in the recess 43 of the intermediate plate 41. Referring to Figure 8, the intermediate plate 41 is removed from the substrate 31. Therefore, the molded portion filled in the groove 43 of the intermediate plate 41 is also removed together with the intermediate plate 41. Various methods can be employed to easily separate the first molding blade 4 in the through hole 44 from the remaining molded portion 34a. For example, the width or depth of the groove 43 can be reduced at the position where the groove 43 and the through hole 44 are connected to each other, so that the remaining molded portion 34a can be easily separated from the first molded portion 34. Referring to Fig. 9, the substrate 31 is subjected to a sawing process so that the substrate 31 can be separated into individual light emitting diodes. A blade or laser can be used to perform the sawing process. After the mineral cutting process, the cutting surface is cleaned. Therefore, as shown in the figure, it is known that the first molding portion 34 is positioned in the wafer type light emitting diode in the region surrounded by the cut surface of the substrate 31. According to the present invention, since the intermediate plate 41' provided in the upper surface of the intermediate plate 41 using the groove 43 is removed together with the intermediate plate 41, the molded portion 34a which has been filled with the groove 43 serving as the flow groove is removed. Therefore, unlike the prior art, the light-emitting diode in which the first molded portion 34 is positioned in the region surrounded by the cut surface of the substrate 31 is manufactured. 10 to 12 are views for explaining a method of manufacturing a light-emitting diode according to another embodiment of the present invention, wherein FIG. 11(a) is a plan view, and FIG. (b) is a cross-sectional view, and FIG. 1 and FIG. 12 are a sectional view and a plan view, respectively. Referring to Fig. 10, the intermediate plate 41 is used to form a first molded portion 34 for covering the light-emitting wafers 32 on the substrate 31 13 respectively, and then the intermediate plate 41 is removed as described above with reference to Figs. Thereafter, the material is coated to form an interval for covering between the first mold portions 34 formed thereon and covering the first molded portion %. An opaque heat-resistant resin (such as a mixture of added resin or an opaque molding material. It can be borrowed, such as 'stencil printing process, transfer molding process; method to mold impervious materials And can be removed by the process of referring to FIG. 11 , by means of a grinding process or the like; directly exposing the upper surface of the first molding portion 34 until 1 month, the material portion % covers the side of the first molding portion 34 = brother = the upper surface of the portion 34. And the exposed portion of the molded portion in the present embodiment 'uses the opaque portion 34 and partially removes the opaque molding material, so that the molded portion 35 is covered with the first to cover the first The side surface member of the molded portion 34 is formed into a second molded portion, which is coated and not in the embodiment of the 'opaque molding material r, which can partially remove the opaque surface.

Referring to Fig. 15, the intermediate plate 41 is used to form a first molded portion of the wafer 32 covering the light-emitting substrate 31 on the substrate 31, and the intermediate plate 4 is removed as described. The second molding portion of the molding portion 34 is formed to cover the first portion separately from the above, and has a second molding portion 75 for use. The secret or the shooting process to form the U intermediate plate can have the same shape as the reference, ^^ = and the groove. The through hole is larger than the intermediate plate 41.丨44. #,二^But the through hole of the intermediate plate 34. I, Qiaodi, the fork part can be adjusted by the size of the through hole of the t-plate, and the first fork system can be formed by the second fork system The first molded portion 34 is covered with a uniform household F. The glazing is 16 and the second difficult portion of the 75 ❺ substrate is formed by the knife coating process so that the substrate can be separated into individual light-emitting diodes. Thus, the light-emitting diode having the second molded portion 75 is formed, and the second mold 75 symmetrically surrounds the side surface of the first molded portion 34 and uniformly covers the upper surface of the second molded portion 34. The second molded portion 75 can be formed to have a uniform thickness on the side surface and the upper surface of the first molded portion 34. In this embodiment, the first molded portion 34 or the second molding; = ° 75 may contain scales. Specifically, in the case where the (four) body is dispersed in the second molding; in the case of %, the phosphor causes the self-luminous wafer to emit a wavelength conversion. Further, the first molding portion 34 and the second molding portion 17 1307 are provided with a ruthenium-emitting body. For example, the first molded portion % may include the two molded portion 75 may include a facet body, thereby providing a white, photodiode. Under such conditions, the light which has been subjected to the wavelength conversion of the first molded portion and the red illuminant can be emitted outward without being absorbed by the green light body of the second molded portion. Therefore, it is possible to prevent loss of light. On the contrary, the first molded portion "34" contains a green light body and the second molded portion 75 may contain a red phosphor. Under such conditions, the light that has been converted by the wavelength of the green phosphor is again converted to red by the wavelength conversion of the red rail, so that the intensity of the red light can be increased.
