【발명의 배경이 되는 기술】 [Technique to become background of invention]
최근 전자기기의 소형화, 고기능화, 대용량화 추세가 확대되고 이에 따른 반도체 패키지의 고밀도화, 고집적화에 대한 필요성이 급격히 커짐에 따라 반도체 칩 크기가 점점 커지고 있으며 집적도 측면에서도 개선하기 위하여 칩을 다단으로 적층하는 스택패키지 방법이 점차로 증가하고 있다. 최근의 반도체 패키지 개발 동향에 있어서는 상술한 반도체 칩들의 소형 박형화 및 고성능화가 급격히 진행되고 있으며 더불어 패키지 대용량화를 목적으로 동일한 패키지 내에 더 많은 칩을 적층할 수 있도록 반도체 웨이퍼의 두께가 모두 100 이하로 극박화 되었고 최근에는 반도체 웨이퍼의 두께가 모두 20 이하로 더욱 극박화되고 있다. 이렇듯 반도체 칩 및 층간 접착필름의 두께가 20 m 이하의 패키지를 제조함에 있어서 접착필름 또한 박형화를 요구되고 있다. Recently, as the trend of miniaturization, high functionality, and large capacity of electronic devices has been expanded, and the necessity for high density and high integration of semiconductor packages has been rapidly increased, the size of semiconductor chips is gradually increasing, and stack packages for stacking chips in multiple stages in order to improve the degree of integration. The method is increasing gradually. In the recent development of semiconductor package development, the miniaturization and high performance of the above-described semiconductor chips are rapidly progressing, and the thickness of the semiconductor wafers is all reduced to 100 or less so that more chips can be stacked in the same package for the purpose of increasing the package capacity. In recent years, the thickness of all semiconductor wafers has become even thinner to 20 or less. As described above, in manufacturing a package having a thickness of 20 m or less, a semiconductor chip and an interlayer adhesive film are also required to be thinner.
한편, 반도체 패키지의 실장은 과정에서는 고온으로 가열하는 단계가 적용되-게 되는데, 예를 들어 적외선 리플루오나 베이퍼페이즈 리플로우, 땜납 딤 등에 의하여 패키지 전체를 가열하여 실장하는 방법이 사용된다. 이러한 고온의 가열 단계에서는 반도체 패키지 전체를 200°C 이상의 온도에 노출시키기 때문에, 반도체 패키지 내부에 존재하는 수분은 폭발적인 기화를 하게 되고, 이러한 기화에 의하여 패키지 균열 또는 리플로우 균열이 발생할 수 있다. 특히, 다이싱 다이본딩 필름 등의 접착제에 수분이 다수 포함되어 있으면, 리플로우 실장 시에 가열에 의해 상기 수분이 증기화되고, 이에 따라 발생하는 증기압에 의하여 다이성 다이본딩 필름이 파괴되거나 박리가 되며 리플로우 균열이 발생할 수 있다. Meanwhile, in the process of mounting the semiconductor package, a step of heating to a high temperature is applied. For example, a method of heating and mounting the entire package by infrared refluorination, vapor phase reflow, solder dim, or the like is used. In such a high temperature heating step, the entire semiconductor package is exposed to a temperature of 200 ° C. or more, and therefore, moisture present in the semiconductor package may explode and vaporize, thereby causing package cracking or reflow cracking. In particular, when a large amount of moisture is contained in an adhesive such as a dicing die-bonding film, the moisture is vaporized by heating at the time of reflow mounting, and the die-die die-bonding film is destroyed or peeled off due to the vapor pressure generated. And reflow cracking may occur.
반도체 패키징 과정에서 발생하는 불량의 대부분은 흡습 후 리플로우 과정쎄서 기판과 접착제 간의 박리 (del aminat ion) 현상으로부터 기인하는데 이에 따라 기판, 접착제 및 반도체 칩간의 응력을 완화하거나 내습성을 향상시키는 방법 등에 관한 연구가 이루어지고 있는 실정이다. Most of the defects in the semiconductor packaging process are caused by the phenomenon of deaminat ion between the substrate and the adhesive during the reflow process after moisture absorption. Thus, the stress between the substrate, the adhesive, and the semiconductor chip is improved or the moisture resistance is improved. There is a study on the situation.

예를 들어, 상기 기재 필름은 저밀도 폴리에틸렌, 선형 폴리에틸렌, 증밀도 폴리에틸렌, 고밀도 폴리에틸렌, 초저밀도 폴리에틸렌, 폴리프로필렌의 랜덤 공중합체, 폴리프로필렌의 블록 공중합체, 호모폴리프로필렌, 폴리메틸펜텐 (polymethylpentene) , 에틸렌-초산비닐 공중합체, 에틸렌 -메타크릴산 . 공중합체, 에틸렌-메틸메타크릴레이트 공중합체, 에틸렌 -아이오노머 공중합체, 에틸렌 -비닐알코올 공중합체, 폴리부텐, 스틸렌의 공중합체 또는 이들의 2종 이상의 흔합물을 들 수 있다. 상기에서 2종 이상의 고분자가 흔합물이 포함되는 기재 필름의 의미는, 전술한 고분자들을 각각 포함한 필름이 2층 이상 적층된 구조의 필름 또는 전술한 고분자들이 2이상 포함된 단일층이 필름을 모두 포함한다. 상기 기재 필름의 두께는 특별히 한정되지 않으며, 통상 10 내지 200 , 바람직하게는 50 卿내지 180 의 두께로 형성된다. 상기 두께가 10 미만이면, 다이싱 공정에서 절단 깊이 (cut depth)의 조절이 불안해 질 우려가 있고, 200 를 초과 하면, 다이싱 공정에서 버 (burr )가 다량 발생하게 되거나, 연신률이 떨어져서 익스펜딩 공정이 정확하게 이루어지지 않을 우려가 있다. For example, the base film is low density polyethylene, linear polyethylene, high density polyethylene, high density polyethylene, ultra low density polyethylene, random copolymer of polypropylene, block copolymer of polypropylene, homopolypropylene, polymethylpentene, Ethylene-vinyl acetate copolymer, ethylene-methacrylic acid. Copolymers, ethylene-methyl methacrylate copolymers, ethylene-ionomer copolymers, ethylene-vinyl alcohol copolymers, polybutenes, styrene copolymers or two or more kinds thereof. The meaning of the base film including a mixture of two or more polymers in the above means that a film having a structure in which two or more layers of films including each of the aforementioned polymers are laminated or a single layer containing two or more of the aforementioned polymers includes both films. do. The thickness of the base film is not particularly limited, usually 10 to 200, preferably 50 kPa to 180 thick.

In the above (meth) acrylate-based resin, the weight average molecular weight may be 100,000 to 1.5 million, preferably 200,000 to 1 million. If the weight average molecular weight is less than 100,000, the coating property or the coarsening force is lowered, there is a possibility that a residue remains on the adherend during peeling, or the adhesive breakdown phenomenon may occur. In addition, when the weight average molecular weight exceeds 1.5 million, the base resin interferes with reaction of the ultraviolet curable compound, and there is a concern that the peeling force may not be reduced efficiently.

(메타)아크릴레이트 또는 데실 (메타)아크릴레이트의 일종 또는 이종 이상의 흔합을 들 수 있다. 알킬의 탄소수가 큰 단량체를 사용할수록, 최종 공중합체의 유리전이온도가 낮아지므로, 목적하는 유리전이온도에 따라 적절한 단량체를 선택하면 된다. One kind or a mixture of two or more kinds of (meth) acrylate or decyl (meth) acrylate is mentioned. Since the higher the carbon number of the alkyl monomer is used, the lower the glass transition temperature of the final copolymer, the appropriate monomer may be selected according to the desired glass transition temperature.

또한, 상기 자외선 경화형 화합물의 종류는 특별히 제한되지 않으며, 예를'들면, 중량평균분자량이 500 내지 300 , 000 정도인 다관능성 화합물 (ex . 다관능성 우레탄 아크릴레이트, 다관능성 아크릴레이트 단량체 또는 올리고머 등)을 사용할 수 있다. 이 분야의 평균적 기술자는 목적하는 용도에 따른 적절한 화합물을 용이하게 선택할 수 있다. 상기 중량 평균 분자량은 GPC법에 의해 측정한 폴리스티렌 환산의 중량 평균 분자량이다. 상기 자외선 경화형 화합물의 함량은 전술한 베이스 수지 100 중량부에 대하여, 5 중량부 내지 400 중량부, 바람직하게는 10 중량부 내지 200 중량부일 수 있다. 자외선 경화형 화합물의 함량이 5 중량부 미만이면, 경화 후 점착력 저하가 층분하지 않아 픽업성이 떨어질 우려가 있고, 400 중량부를 초과하면, 자외선 조사 전 점착제의 움집'력이 부족하거나, 이형 필름 등과의 박리가 용이하게 이루어지지 않을 우려가 있다. In addition, the type of the ultraviolet curable compound is not particularly limited, and for example, 'a multifunctional compound having a weight average molecular weight of about 500 to 300, 000 (ex. Polyfunctional urethane acrylate, polyfunctional acrylate monomer or oligomer, etc.) ) Can be used. The average person skilled in the art can easily select the appropriate compound according to the intended use. The said weight average molecular weight is the weight average molecular weight of polystyrene conversion measured by GPC method. The content of the ultraviolet curable compound may be 5 parts by weight to 400 parts by weight, preferably 10 parts by weight to 200 parts by weight, based on 100 parts by weight of the base resin described above. If the content of the ultraviolet curable compound is less than 5 parts by weight, there is a risk that the drop in adhesive strength after curing is not sufficient, and the pick-up property may be degraded. If the content of the ultraviolet curable compound exceeds 400 parts by weight, the adhesive force of the adhesive before UV irradiation is insufficient, or with a release film or the like. There exists a possibility that peeling may not be performed easily.

The type of photoinitiator is also not particularly limited, and in this field It is possible to use a known general initiator, and the content thereof may be 0.05 part by weight to 20 parts by weight with respect to 100 parts by weight of the ultraviolet curable compound. If the content of the photoinitiator is less than 0.05 parts by weight, there is a risk that the curing reaction by the ultraviolet irradiation is insufficient, the pickup properties are lowered. If the content of the photoinitiator exceeds 20 parts by weight, the crosslinking reaction occurs in a short unit or the mabanung UV-curable compound It may generate and cause residue on the surface of the adherend, or the peeling force after curing may be too low, resulting in deterioration of pick-up performance.

The crosslinking agent may be included in an amount of 2 parts by weight to 40 parts by weight, preferably 2 parts by weight to 20 parts by weight, based on 100 parts by weight of the base resin. If the content is less than 2 parts by weight, the cohesive force of the pressure-sensitive adhesive may be insufficient, if it exceeds 20 parts by weight, the adhesive strength before ultraviolet irradiation is insufficient, there is a fear that chip scattering may occur.

【표 2】 실험예의 결과 Table 2 Results of Experimental Example
상기 표 2에 나타난 바와 같이, 실시예 1 내지 2에서 제조된 접착 필름은 85°C 및 85 조건에서 168시간 노출하여도 흡습율이 1.50wt%이하가 되며, 고온 경화 및 흡습 후 리플로우 과정에서 기판과 접착제 간의 박리 현상이 발생하지 않는다는 점이 확인되었다. 이에 반해, 비교예 1의 접착 필름은 낮은 흡습율을 갖는 아크릴레이트계 수지를 포함함에도 불구하고 85°C 및 85%RH 조건에서 168시간 노출 이후에 흡습율이 1.75 wt%이고, 고은 경화 및 흡습 후 리플로우 과정에서 기판과 접착제 간의 박리 현상이 발생한 점이 확인되었다. 이는 비교예 1의 접착 필름이 접착제 흡습율을 조정할 수 있는 바이페닐 노볼락 에폭시 수지를 낮은 함량, 예를 들어 약 3중량 % 미만으로 포함함에 따른 것으로 보인다. As shown in Table 2, the adhesive film prepared in Examples 1 to 2 is less than 1.50wt% moisture absorption even after exposure to 168 hours at 85 ° C and 85 conditions, in the reflow process after high temperature curing and moisture absorption It was confirmed that no peeling phenomenon occurred between the substrate and the adhesive. In contrast, although the adhesive film of Comparative Example 1 contained an acrylate-based resin having a low moisture absorption rate, the moisture absorption rate was 1.75 wt% after exposure to 168 hours at 85 ° C. and 85% RH conditions, and it was cured and absorbed. It was confirmed that peeling phenomenon occurred between the substrate and the adhesive during the reflow process. This is believed to be due to the fact that the adhesive film of Comparative Example 1 contains a biphenyl novolac epoxy resin capable of adjusting the adhesive hygroscopicity in a low content, for example, less than about 3% by weight.
또한, 비교예 2의 접착 필름은 상대적으로 높은 흡습율을 갖는 아크릴레이트계 수지를 포함하고 에폭시 수지로서 바이페닐 노볼락 에폭시 수지를 포함하지 않음에 따라서, 85°C 및 85«H 조건에서 168시간 노출 이후에 흡습율이 2. 1 »에 달하고, 고온 경화 및 흡습 후 리플로우 과정에서 기판과 접착제 간의 박리 현상이 크게 발생한 점이 확인되었다. In addition, the adhesive film of Comparative Example 2 contains an acrylate-based resin having a relatively high moisture absorption and does not contain a biphenyl novolac epoxy resin as an epoxy resin, 168 hours at 85 ° C and 85 «H conditions After the exposure, the moisture absorption rate reached 2.1 », and it was confirmed that the peeling phenomenon between the substrate and the adhesive was large in the reflow process after the high temperature curing and the moisture absorption.
그리고, 비교예 3 및 비교예 4의 접착 필름은 바이페닐 노볼락 에폭시 수지를 포함하였으나, 상대적으로 높은 흡습율을 갖는 아크릴레이트계 수지를 포함함에 따라서, 85°C 및 85%RH 조건에서 168시간 노출 이후에 흡습율이 각각 1.9 wt 및 2.3wt¾>이고, 고온 경화 및 흡습 후 리플로우 과정에서 기판과 접착제 간의 박리 현상이 발생한 점이 확인되었다. And, although the adhesive film of Comparative Example 3 and Comparative Example 4 contained a biphenyl novolak epoxy resin, but includes an acrylate resin having a relatively high moisture absorption rate, 168 hours at 85 ° C and 85% RH conditions After exposure, the moisture absorption rate was 1.9 wt and 2.3 wt¾>, and it was confirmed that the peeling phenomenon occurred between the substrate and the adhesive during the reflow process after the high temperature curing and the moisture absorption.
