Description
본 발명은 반도체 봉지제용 에폭시 수지 조성물에 관한 것으로, 더욱 상세하게는 난연제를 포함하지 않고, 자기소화성을 갖는 에폭시 수지와 다방향족 경화제 또는 다방향족 경화제와 인변성 페놀 노블락 경화제의 혼합 경화제를 사용함으로써 난연성을 향상시킨 것을 특징으로 하는 반도체 봉지제용 에폭시 수지 조성물에 관한 것이다.The present invention relates to an epoxy resin composition for a semiconductor encapsulant, and more particularly, does not contain a flame retardant, and is flame retardant by using a mixed resin of an epoxy resin having a self-extinguishing property, a polyaromatic curing agent or a polyaromatic curing agent, and a modified phenolic noblock curing agent. It is related with the epoxy resin composition for semiconductor sealing agents which improved.
일반적으로 반도체 봉지제용 에폭시 수지에 대해서는 난연성이 요구되며, 대부분의 반도체 업체에서는 UL-94-V-O 수준의 난연성을 요구하고 있다. 반도체 봉지제용 에폭시 수지에 난연성을 부여하기 위해서는 난연제를 사용하여 반도체 봉지제용 에폭시 수지를 제조하는데, 난연제로는 주로 할로겐계 난연제 또는 할로겐계 난연제의 단점을 보완한 비할로겐계 난연제가 사용되고 있다. 할로겐계 난연제로는 구체적으로 브롬이나 염소계의 할로겐계 난연제를 사용하며, 이것과 함께 난연 상승 효과가 우수한 Sb203을 난연보조제로 사용한다. 한편, 비할로겐계 난연제로는 인화합물과 같은 비할로겐계 난연제를 사용하고 수산화알루미늄과 같은 금속수산화물이나 징크보레이트와 같은 무기금속화합물을 난연보조제로 사용하고 있다. 이러한 난연제를 반도체 봉지제용 에폭시 수지 조성물에 첨가할 때는 이러한 난연제를 에폭시 수지와 믹싱 및 니딩한 후 냉각시켜 최종 제품으로 타블레팅하여 제조한다.In general, flame retardancy is required for an epoxy resin for a semiconductor encapsulant, and most semiconductor companies require a flame retardancy of UL-94-VO level. In order to impart flame retardancy to an epoxy resin for semiconductor encapsulant, a flame retardant is used to prepare an epoxy resin for semiconductor encapsulant. As a flame retardant, a halogen-based flame retardant or a non-halogen-based flame retardant which supplements disadvantages of a halogen-based flame retardant is used. As the halogen-based flame retardant, a bromine or chlorine-based halogen flame retardant is used, and Sb 2 0 3 having excellent flame retardant synergistic effect is used as a flame retardant aid. On the other hand, non-halogen-based flame retardants are used non-halogen-based flame retardants such as phosphorus compounds and inorganic metal compounds such as aluminum hydroxide or zinc borate as a flame retardant aid. When the flame retardant is added to the epoxy resin composition for semiconductor encapsulant, the flame retardant is prepared by mixing and kneading with the epoxy resin and then cooling and tableting the final product.
그러나, 할로겐계 난연제를 사용하는 경우에는 소각시 또는 화재시에 다이옥신(dioxin)이나 다이퓨란(difuran) 등의 유독성 발암물질을 발생시키고 연소시 발생하는 HBr 및 HCl 등의 가스는 인체에 유해하며 반도체 칩이나 리드프레임에서 부식(corrosion)을 발생시키는 주원인으로 작용한다. 한편 인화합물과 같은 비할로겐계 난연제의 경우에는 연소시 미미하지만 약간의 독성을 가지고 있고 대량의 무기인산류를 강과 하천에 방류할 경우 하천의 부영양화를 촉진하여 심각한 환경오염을 초래할 수 있다.However, when halogen-based flame retardants are used, toxic carcinogens such as dioxin or difuran are generated during incineration or fire, and gases such as HBr and HCl generated during combustion are harmful to the human body, and semiconductors It acts as the main cause of corrosion in chips or leadframes. On the other hand, non-halogen flame retardants such as phosphorus compounds are insignificant at the time of combustion, but have some toxicity. If large amounts of inorganic phosphates are discharged into rivers and rivers, they can cause eutrophication of rivers and cause serious environmental pollution.
본 발명의 목적은 상술한 바와 같은 종래 기술에서 난연성 부여를 위해 사용되었던 인체 및 환경에 대해 유해성을 가지는 할로겐계 및 비할로겐계 난연제를 사용하지 않고 자기소화성을 가진 에폭시 수지와 경화제를 사용하여 난연성이 우수한 반도체 봉지제용 에폭시 수지 조성물을 제공하는 것이다. An object of the present invention is to use a flame retardant using an epoxy resin and a curing agent having self-extinguishing properties without using halogen-based and non-halogen-based flame retardants that are harmful to humans and the environment that were used for imparting flame retardancy in the prior art as described above.

본 발명의 반도체 봉지제용 에폭시 수지 조성물을 구성하는 다방향족 에폭시 수지는 당량이 250-300이고 하기 화학식 1의 구조를 갖는다.The polyaromatic epoxy resin constituting the epoxy resin composition for a semiconductor encapsulant of the present invention has an equivalent weight of 250-300 and has the structure of Formula 1 below.
(상기 식에서, n은 0-7 사이의 수이다.)(Where n is a number between 0 and 7)
본 발명에서 사용되는 상기 다방향족 에폭시 수지는 페놀 골격을 근간으로 해서 중간에 다이페닐을 가지고 있는 구조를 하고 있기 때문에, 수분흡수율이 낮고 인성이 우수하며, 내산화성이 좋고 접착력이 우수할 뿐만 아니라 내크랙성 및 난연성이 우수하다. 이러한 본 발명에서 사용되는 다방향족 에폭시 수지는 가교 밀도가 낮아서 착화시 고온에서 고무 형태의 발포층을 형성한다.Since the polyaromatic epoxy resin used in the present invention has a structure having diphenyl in the middle based on a phenol skeleton, it has a low water absorption rate, excellent toughness, good oxidation resistance, good adhesion and It is excellent in crackability and flame retardancy. The multi-aromatic epoxy resin used in the present invention has a low crosslinking density to form a foamed layer in the form of a rubber at high temperature during complexing.
본 발명의 반도체 봉지제용 에폭시 수지 조성물에서 다방향족 에폭시 수지의 사용량은 전체 조성물중 5.0-15.0중량%인 것이 바람직하며, 상기 범위를 벗어나면 본 발명의 목적을 달성할 수 없다.The amount of the multi-aromatic epoxy resin in the epoxy resin composition for semiconductor encapsulant of the present invention is preferably 5.0-15.0% by weight in the total composition, it can not achieve the object of the present invention outside the above range.
(B) 다방향족 경화제 또는 다방향족 경화제와 인변성 페놀노블락 경화제의 혼합 경화제 (B) A mixed curing agent of a polyaromatic curing agent or a polyaromatic curing agent and a modified phenol noblock curing agent
본 발명의 반도체 봉지제용 에폭시 수지 조성물중의 경화제는 하기 화학식 2의 다방향족 경화제 또는 상기 다방향족 경화제와 하기 화학식 3의 인변성 페놀노블락 경화제를 혼합한 것이다.The hardening | curing agent in the epoxy resin composition for semiconductor sealing agents of this invention mixes the polyaromatic hardening | curing agent of following General formula (2) or the said polyaromatic hardening | curing agent, and the phosphate phenol noblock hardening | curing agent of following General formula (3).
(상기 식에서, n은 0-7 사이의 수이다.)(Where n is a number between 0 and 7)
(상기 식에서, n은 0-7 사이의 수이다.)(Where n is a number between 0 and 7)
본 발명에서 상기 화학식 2의 다방향족 경화제는 상기 다방향족 에폭시 수지와 반응하여 연소시에 에폭시 수지 조성물에 발포층을 형성하여 주변의 산소 및 연소열의 전달을 차단함으로써 난연성을 달성하게 된다. 본 발명의 반도체 봉지제용 에폭시 수지 조성물에서는 가교 구조에 의한 다방향족 구조의 내열분해성과 발포층의 안정성에 의해 난연성이 확보된다. 기존의 오르소크레졸노블락 에폭시 수지와 페놀노블락계 경화제가 사용되는 에폭시 수지 조성물에서는 유리전이온도가 높아서 내열성이 우수하지만 가교밀도가 높아 구조가 경직되어 발포층이 쉽게 형성되지 못하여 난연성이 나타나지 않게 되는 반면에, 본 발명에서는 다방향족 에폭시 수지와 다방향족 경화제가 결합하여 우수한 난연성이 확보된다. 또한 인변성 페놀노블락 경화제를 다방향족 경화제와 함께 사용하면 다방향족 경화제만을 단독으로 사용하는 경우에 비해 난연성이 더 향상되는 효과를 수득할 수 있다. 본 발명에서 다방향족 경화제와 인변성 페놀노블락 경화제의 혼합비는 100:0 내지 50:50의 범위내이다.In the present invention, the multi-aromatic curing agent of Formula 2 reacts with the multi-aromatic epoxy resin to form a foam layer in the epoxy resin composition during combustion to achieve flame retardancy by blocking the transfer of the surrounding oxygen and combustion heat. In the epoxy resin composition for semiconductor encapsulants of the present invention, flame retardancy is secured by thermal decomposition resistance of the multi-aromatic structure and crosslinked structure stability. In the conventional epoxy resin composition using the orthocresol noblock epoxy resin and the phenol noblock curing agent, the glass transition temperature is high, and the heat resistance is excellent, but the crosslinking density is high, the structure is rigid, and the foam layer is not easily formed, so that the flame retardancy does not appear. In the present invention, the polyaromatic epoxy resin and the polyaromatic curing agent are bonded to each other to ensure excellent flame retardancy. In addition, when the modified phenol noblock curing agent is used together with the polyaromatic curing agent, it is possible to obtain an effect of further improving the flame retardancy compared to the case of using only the polyaromatic curing agent alone. In the present invention, the mixing ratio of the polyaromatic curing agent and the modified phenol noblock curing agent is in the range of 100: 0 to 50:50.
본 발명에서 사용되는 인변성 페놀노블락 경화제는 기존의 페놀노블락 경화제에 인을 함유한 형태의 경화제로서 내산화성, 내후성 및 내열성이 우수할 뿐만 아니라 난연성이 우수한 특징을 갖는다.Phosphorus-modified phenol noblock curing agent used in the present invention is a curing agent of the form containing phosphorus in the existing phenol noblock curing agent as well as excellent in oxidation resistance, weather resistance and heat resistance as well as excellent flame resistance.
본 발명에서 다방향족 경화제와 인변성 페놀노블락 경화제의 사용량은 전체 조성물에 대하여 1.99 내지 9.95중량%이다. 본 발명의 반도체 봉지제용 에폭시 수지 조성물에서 경화제의 함량이 1.99중량% 미만이면 경화제 사용시 경화반응이 충분히 일어나지 않아서 성형이 이루어지지 않게 되고 물성이 현저하게 저하되며, 이와 반대로 9.95중량%를 초과하면 봉지제 내에 잔류물이 형성되어 신뢰성이 불량하게 되며 불필요한 원가 상승의 원인이 된다.In the present invention, the amount of the polyaromatic curing agent and the modified phenol noblock curing agent is 1.99 to 9.95% by weight based on the total composition. When the content of the curing agent in the epoxy resin composition for semiconductor encapsulant of the present invention is less than 1.99% by weight, the curing reaction does not sufficiently occur when the curing agent is used, so that molding is not performed and the physical properties are significantly lowered. Residues are formed in them, which leads to poor reliability and unnecessary cost rises.
(C) 경화촉진제(C) curing accelerator
본 발명에서 경화촉진제로는 트리페닐포스핀(TPP:triphenylphosphine)을 사용하며 이를 단독으로 사용하거나 또는 경화제와 혼합하여 용융하여 멜트마스타베치(MMB)를 만들어 사용한다. 본 발명의 반도체 봉지제용 에폭시 수지 조성물중 경화촉진제의 함량은 전체 조성물중 0.002 내지 0.25중량%로, 경화촉진제의 함량이 0.25중량%를 초과하면 경화반응에 이상이 발생하여 물성이 저하될 수 있으므로 상기 범위내로 사용하되 에폭시 수지 봉지제의 공정조건에 따라 조절하여 사용할 수 있다.In the present invention, as a hardening accelerator, triphenylphosphine (TPP: triphenylphosphine) is used and used alone or mixed with a hardening agent to melt to make a melt masterbatch (MMB). The content of the curing accelerator in the epoxy resin composition for semiconductor encapsulant of the present invention is 0.002 to 0.25% by weight of the total composition, when the content of the curing accelerator exceeds 0.25% by weight, abnormalities in the curing reaction may occur and the physical properties may be lowered. It can be used within the range of control according to the process conditions of the epoxy resin encapsulant.
(D) 무기충전제(D) inorganic filler
본 발명의 반도체 봉지제용 에폭시 수지 조성물중 무기충전제는 평균입도가 0.1-40㎛인 용융실리카를 사용하며, 충전량은 조성물 전체에 대해 74-90중량%이다. 무기충전제의 충전량이 74중량% 미만이면 충분한 강도를 얻기 어럽게 되며 수분 흡수로 인한 알루미늄 패드 부식이 일어날 가능성이 높아지고, 이와 반대로 90중량%를 초과하면 유동성이 좋지 않아서 반도체 조립시 성형성에서 불량이 발생할 수 있다. 무기충전제를 직접 투입할 경우 믹싱시 분산이 잘 되지 않고 다른 성분 원료와 상용성이 좋지 않아서 반도체 조립시 성형성 불량을 야기하는 문제점이 발생할 수 있다. 따라서, 본 발명에서 무기충전제는 커플링제로 코팅하여 첨가하는 것이 바람직하며, 이와 같이 하면 분산성이 향상되고 무기물과 유기물간의 상용성이 증가되어 성형성이 우수해진다.Inorganic fillers in the epoxy resin composition for semiconductor encapsulants of the present invention use a molten silica having an average particle size of 0.1-40㎛, the filling amount is 74-90% by weight relative to the entire composition. If the amount of the inorganic filler is less than 74% by weight, it is difficult to obtain sufficient strength, and the possibility of corrosion of the aluminum pad due to moisture absorption increases. On the contrary, if the content of the inorganic filler exceeds 90% by weight, the fluidity is not good. May occur. When the inorganic filler is directly added, the dispersion may not be well performed during mixing, and the compatibility with other ingredients may be poor, resulting in poor moldability when assembling the semiconductor. Therefore, in the present invention, the inorganic filler is preferably added by coating with a coupling agent. In this case, the dispersibility is improved and the compatibility between the inorganic material and the organic material is increased, thereby improving the moldability.
(E) 커플링제(E) coupling agent
본 발명에서 사용되는 커플링제는 아민계 실란 화합물이며 그의 사용량은 전체 수지 조성물중 0.02-1.0 중량%이다. 커플링제를 1.0 중량%를 초과하는 양으로 과량 사용하면 미반응 커플링제가 잔류하여 성형성에 취약한 결과를 초래하며, 이와 반대로 0.02 중량% 미만으로 사용하면 분산성이 저하되어 니딩(kneading)시 겔(gel) 불량 발생율이 높게 나타나며 반도체 조립시 성형성 불량이 발생하기 때문에 본 발명에서 커플링제는 상기 범위내로 사용하는 것이 필요하다.The coupling agent used in the present invention is an amine silane compound, and the amount of the coupling agent is 0.02-1.0 wt% in the total resin composition. Excessive use of the coupling agent in an amount exceeding 1.0% by weight results in unreacted coupling agent remaining, which results in weak moldability. On the contrary, when the coupling agent is used in an amount less than 0.02% by weight, the dispersibility is lowered. Gel) Since the defect occurrence rate is high and moldability defects occur during semiconductor assembly, the coupling agent in the present invention needs to be used within the above range.
