When the fluorophor sheet material to the state laminated with substrate is cut, singualtion can be carried out by substrate, or
Can also by fluorophor sheet material singualtion, without being cut to substrate.Or it is also possible to introduce on substrate and does not penetrate through
Cut line, so-called semi-shear (half cut).The fluorophor sheet material for having carried out singualtion as described above is heat fused in
On the light-emitting surface of each LED chip.When fluorophor sheet material is carried out singualtion by substrate, singualtion LED chip attaches
The one of the process of cutting is illustrated in Figure 13.It include: the process that fluorophor sheet material is cut into monolithic in the process of Figure 13;And in institute
Desired temperature crimps the fluorophor sheet material for being already cut into monolithic, thus the process for being attached at LED chip.Figure 13's
It (a) is that the fluorophor sheet material 2 of the state laminated with substrate 20 is fixed on the case where being fixed temporarily sheet material 21.Shown in Figure 13
In process, singualtion is carried out for fluorophor sheet material 2 and substrate 20, therefore be fixed on be fixed temporarily sheet material 21 in advance, so that
It must operate and be easy.Next, carrying out cutting to fluorophor sheet material 2 and substrate 20 as shown in (b) to carry out singualtion.It connects
, as shown in (c), on the LED chip 1 being installed on installation base plate 7, the fluorophor sheet material 2 and base that will be singulated
Material 20 is aligned, and as shown in (d), using heating crimping tool 22, is crimped with desired temperature.At this point, in order to
The engaging-in air not between fluorophor sheet material 2 and LED chip 1 preferably carries out crimping process under vacuum or under decompression.After crimping
It lets cool to room temperature, such as removes substrate 20 shown in (e).Herein, whens substrate 20 is glass etc., substrate can not also be removed and
As directly carry out shown in (f) using.
In addition, in the continuous situation of substrate by fluorophor sheet material singualtion when, directly can disposably make its hot melt

Change the process of LED chip attaching cutting one is illustrated in Figure 14.It also include: to cut fluorophor sheet material in the process of Figure 14
It is heated at the process of monolithic and to the fluorophor sheet material for being already cut into monolithic, thus the process for being attached at LED chip.
In the example of the process shown in Figure 14, firstly, when by process shown in (b) by fluorophor 2 singualtion of sheet material, substrate 20
It is not singulated.In (b) of Figure 14, substrate 20 is absolutely not cut, but as long as substrate 20 be it is continuous, then can also be by
It cuts part.Then, as shown in (c), the surface before making the fluorophor sheet material 2 being singulated and cutting is formed with LED chip
Chip 23 it is opposed, aligned.It, will be glimmering with desired temperature using heating crimping tool 22 in the process shown in (d)
Body of light sheet material 2 is crimped with the chip 23 that the surface before cutting is formed with LED chip.At this point, in order not in fluorophor sheet material 2
It is formed with engaging-in air between the chip 23 of LED chip 1 with the surface before cutting, is preferably crimped under vacuum or under decompression
Process.It is let cool after crimping to room temperature, after removing substrate 20 as shown in (e), chip is carried out cutting to carry out singualtion,
Obtain the LED chip 24 with fluorophor sheet material being singulated as shown in (f).
In the LED chip for the wafer-level being disposably heat fused in fluorophor sheet material before cutting, can also paste
Fluorophor sheet material is cut together with the attached cutting with LED chip wafer.Fluorophor sheet material and chip is latter in attaching
One of process when being cut to secondary property is illustrated in Figure 15.It include: with desired temperature in the process of Figure 15 by fluorophor
Sheet material is crimped on the process on a plurality of LED chips to disposably be attached;And to fluorophor sheet material and LED chip into
The process that row is disposably cut.In the process of Figure 15, in the case where not carrying out cutting processing to fluorophor sheet material 2 in advance,
Being formed with 2 side of fluorophor sheet material with the surface before cutting, the chip 23 of LED chip is opposed to go forward side by side
Row contraposition.It then,, will be before fluorophor sheet material 2 and cutting with desired temperature using heating crimping tool 22 as shown in (b)
Surface be formed with the chip 23 of LED chip and crimped.In this case, in order not to the table before fluorophor sheet material 2 and cutting
Face is formed with engaging-in air between the chip 23 of LED chip, preferably carries out crimping process under vacuum or under decompression.It is put after crimping
It is cooled to room temperature, after removing substrate 20 as shown in (c), while being cut to chip, fluorophor sheet material 2 is cut
It cuts, to carry out singualtion, obtains the LED chip 24 with fluorophor sheet material being singulated as shown in (d).In addition,
The surface before fluorophor sheet material 2 and cutting is formed with by LED with desired temperature using heating crimping tool as shown in (b)
After the chip 23 of chip is crimped, such as shown in (e) in the case where not peeling base 20 by substrate also with fluorophor sheet material
It is cut together and carries out singualtion, (it has base to the fluorophor sheet material that has for obtaining being singulated as shown in (f)
Material) LED chip 24.In this case, can not remove and directly carry out using for other than glass whens substrate 20 is glass etc.
Plastic foil when, substrate can be installed on the LED chip with fluorophor sheet material (it has substrate) will be singulated
Afterwards, substrate is removed.
Using arbitrary process in above-mentioned Figure 13~15, have fluorophor sheet material is attached at upper surface
When the LED chip of electrode, in order to remove the fluorophor sheet material of electrode section, it is expected that in advance to the portion before attaching fluorophor sheet material
Divide and carries out aperture processing.Aperture processing can suitably use method known to laser processing, mold perforation etc., but since laser adds
Labour union causes the burning of resin, the deterioration of fluorophor, so more preferably being processed using the perforation of mold.When implementing perforation processing,
Since perforation processing can not be carried out after fluorophor sheet material to be attached to LED chip, so must be before attaching to phosphor plates
Material implements perforation processing.For using the perforation of mold processing, it can be opened according to electrode shape of the LED chip of attaching etc.
The hole of arbitrary shape, arbitrary size.For the size in hole, shape, as long as can be designed mold, it can be formed arbitrary big
Small, arbitrary shape, but the electrode engagement part in order not to reduce the area of light-emitting surface, on the LED chip of 1mm square or so
Preferably 500 μm hereinafter, with the size correspondingly with 500 μm of holes formed below.In addition, carrying out wire bonding (wire
) etc. bonding electrode needs to have a degree of size, at least 50 μm or so of size, therefore hole and the size phase
It is 50 μm or so with answering.When the size in hole is excessive compared with for electrode, light-emitting surface exposes that light leakage occurs, LED package
Color characteristics decline.In addition, being engaged bad in wire bonding with wire contacts when too small compared with for electrode.Cause
This, for aperture processing, it is necessary to 50 μm or more and 500 μm of apertures below are processed with the high-precision within ± 10%,
In order to improve the precision of perforation processing, store elastic modulus G ' of the fluorophor sheet material at 25 DEG C meets 1.0 × 104Pa≤G’≤
1.0×106Pa and tan δ < 1 also becomes extremely important.
It is aligned simultaneously by the prescribed portion of the fluorophor sheet material and LED chip that implement cutting processing aperture processing
It is necessary to have the adhering devices of optical registration (alignment) mechanism when attaching.At this point, make fluorophor sheet material and LED chip it is close and
It is aligned and is difficult in operation, practical upper often implementation in the following manner: make fluorophor sheet material and LED chip gently
It is aligned in the state of contact.At this point, if fluorophor sheet material has adhesiveness, make that it is contacted with LED chip and movement is
It is very difficult.For fluorophor sheet material lamilate of the invention, without adhesiveness, therefore hold if if room temperature is aligned
Easily carry out the contraposition for contacting fluorophor sheet material gently with LED chip.
