The present invention refers to correspondingly limited as shown in of Figure 15 (a), element (D) is number 1 pressure-sensitive adhesive layer (12) and attached to the, number 1 pressure-sensitive adhesive layer (12) and number 2 pressure-sensitive adhesive layer (22) changes according to a wavelength of light emitting unit 70 is composed of a material.

[88]

As shown in (b) of Figure 15, number 1 pressure-sensitive adhesive layer (12) wavelength of the light projected on the (WB1 ) Is number 2 pressure-sensitive adhesive layer (22) wavelength of the light projected on the (WB2 ) When shorter than, number 1 pressure-sensitive adhesive layer (12) is number 2 pressure-sensitive adhesive layer (22) in the coin number 1 further advance compared to prevent blow-in depth (dK1 ) The size of the number 2 blow-in depth (dK2 ) Formed thereof smaller than, the number 1 number 2 formed at an outer portion of adhesion than the first chemistry.

[89]

The release step (S40) of Figure 15 (c) subjected to surface as shown, element (D) is number 2 pressure-sensitive adhesive layer (22) of attaching a number 1 to adhesive layer (12) mold release encoded.

[90]

As a result, number 1 pressure-sensitive adhesive layer (12) and number 2 pressure-sensitive adhesive layer (22) first and the degree to which a light signal which is cured to form a process (D) number (D) to determine the direction in which the exactness of transfer and releasing the gate electrode is equal to or higher.

[91]

As shown in fig. 16, carrier film (10) can be moved by engagement with the roller (R).

[92]

Specifically, carrier film (10) and is disposed along the cylindrical roller (R) enclosed, roller (R) about the rotating axis of rotational movement number 2 and adhesive layer (22) is attached to the element number 1 (D) adhesive layer (12) are transferred.

[93]

The, element (D) is carrier film (10) and the substrate (20) depressurized the pressing step (S10) number 1 in adhesive layer (12) and they are in element (D) to a uniform depth of an entire pushed, number 1 pressure-sensitive adhesive layer (12) is projected from a surface of curved shape forming a flat projections (12a) having a predetermined wavelength.

[94]

Number 1 of curve shape having adhesive layer (12) and, flat projections (12a) number 1 having an adhesive layer (12) is removed (D) inserted slot depth (d3 ) When the same, shown in (a) of Figure 17 in place of an adhesive layer having curvilinear number 1 (12) (D) shown in (b) of Figure 17 to press-element region of the flat projection (12a) formed smaller than the area of the press-fitted element (D).

[95]

Specifically, of Figure 17 (a) of the roller (R) shown in element (D) conferred on the largest by blow-in depth (d3 ) Having a wafer from the center of the adhesive is formed from a relatively small number 1 due to non-uniform X2 blow-in depth, (b) of Figure 17 shown in element (D) has a planar projection (12a) uniform blow-in depth (d3 ) Strength corresponding to, number 1 in addition adhesion uniformly formed.

[96]

The flat projections (12a) including number 1 a adhesive layer (12) is more stable than a number 2 elements (D) adhesive layer (22) release from to be employed therein.

[97]

On the other hand, a device using a roller (R) generally (D) case, roller (R) load number through substrate (20) where a thin metal can. The roller (R) in that it provides additional flat projections (12a) without forming a, roller (R) substrate (20) number by using only the contact load acting between the substrate (20) number 1 in contact with the adhesive layer (12) to regulate the size of, substrate (20) number 1 in contact with the adhesive layer (12) can be thin metal area of, the number 1 is formed as a flat adhesive layer (12) in the area of uniform blow-in [kiph this element (D) is pushed is equal to or higher.

[98]

The, substrate (20) is made of the butanes.

[99]

The present invention refers to correspondingly limited, carrier film (10) can be formed flat, is made of a carrier film (10) number 1 (D) ion implantation is performed on the adhesive layer (12) is formed in the uniform layer is formed on the wafer blow-in depth between number 1 can be stably transferring element is equal to or higher.

[100]

Hereinafter, a method of the present invention element transfer plate and by transfer on electronic number number bath together by use of electronic number article is described other article manufacturing method.

[101]

Wherein, element is micro LED can be, electronic number article such as a flat display or digital (digital signage) specifically between electronic components such as a circuit board or article number be inter-perfect electronic number. Circuit board include printed circuit boards, liquid crystal circuit board, display panel circuit board, such as a publicly known signal in various corresponding to this substrate, printed circuit board include publicly known soft, including both the circuit board can be rigid or around year, the present invention according to element transfer method described above can be electronic by article number number high pressure liquid coolant.
