Description
본 발명은 열경화성 수지 조성물, 필름형 접착제, 접착 시트 및 반도체 장치의 제조 방법에 관한 것이다.The present invention relates to a method for producing a thermosetting resin composition, a film adhesive, an adhesive sheet, and a semiconductor device.
종래 반도체 칩과 반도체 칩 탑재용 지지 부재의 접합에는 주로 은 페이스트가 사용되고 있다. 그러나, 최근의 반도체 칩의 소형화·집적화에 따라, 사용되는 지지 부재에도 소형화, 세밀화가 요구되게 되고 있다. 한편, 은 페이스트를 이용하는 경우에는, 페이스트의 돌출 또는 반도체 칩의 기울기에 기인하는 와이어 본딩 시에 있어서의 문제점 발생, 막 두께 제어의 곤란성, 보이드 발생 등의 문제가 생기는 경우가 있다. Conventionally, silver paste is mainly used for bonding between a semiconductor chip and a support member for mounting the semiconductor chip. However, along with the miniaturization and integration of semiconductor chips in recent years, miniaturization and miniaturization are also required for support members used. On the other hand, when silver paste is used, problems such as occurrence of problems at the time of wire bonding due to protrusion of the paste or inclination of the semiconductor chip, difficulty in film thickness control, generation of voids, and the like may occur.
그 때문에, 최근 반도체 칩과 지지 부재를 접합하기 위한 필름형 접착제가 사용되고 있다(예컨대 특허문헌 1 참조). 다이싱 테이프와 다이싱 테이프 상에 적층된 필름형 접착제를 구비하는 접착 시트를 이용하는 경우, 반도체 웨이퍼의 이면에 필름형 접착제를 붙이고, 다이싱에 의해서 반도체 웨이퍼를 개편화(個片化)함으로써, 필름형 접착제 구비 반도체 칩을 얻을 수 있다. 얻어진 필름형 접착제 구비 반도체 칩은, 필름형 접착제를 통해 지지 부재에 붙여, 열압착에 의해 접합할 수 있다. Therefore, in recent years, a film adhesive for bonding a semiconductor chip and a supporting member has been used (for example, see Patent Document 1). In the case of using an adhesive sheet comprising a dicing tape and a film adhesive laminated on the dicing tape, the film adhesive is pasted on the back side of the semiconductor wafer and the semiconductor wafer is separated into pieces by dicing, A semiconductor chip with a film adhesive can be obtained. The obtained semiconductor chip with film adhesive can be attached to a support member via a film adhesive and joined by thermal compression bonding.
그러나, 반도체 칩의 사이즈가 작아짐에 따라서 가압 시에 단위 면적당 걸리는 힘이 커지기 때문에, 고온 가압 처리(예컨대 가압 큐어 등)에 있어서, 필름형 접착제가 반도체 칩으로부터 돌출되는 블리드라는 현상이 발생하는 경우가 있다.However, since the force applied per unit area during pressurization increases as the size of the semiconductor chip decreases, a phenomenon called bleed in which the film adhesive protrudes from the semiconductor chip may occur in high-temperature pressure treatment (eg, pressure curing). there is.
또한, 필름형 접착제를 와이어 매립형 필름형 접착제인 FOW(필름 오버 와이어(Film Over Wire)) 또는 반도체 칩 매립형 필름형 접착제인 FOD(필름 오버 다이(Film Over Die))로서 이용하는 경우는, 매립성을 향상시킨다는 관점에서, 열압착 시에 높은 유동성이 요구된다. 그 때문에, 블리드의 발생 빈도 및 양이 더욱 커지는 경향이 있다. 경우에 따라서는, 블리드가 반도체 칩 상면에까지 생기는 경우가 있고, 이에 따라, 전기 불량 또는 와이어 본딩 불량으로 이어질 우려가 있다. Further, when the film adhesive is used as FOW (Film Over Wire), which is a wire-embedded film adhesive, or FOD (Film Over Die), which is a semiconductor chip-embedded film adhesive, the embedding property is From the viewpoint of improvement, high fluidity is required at the time of thermocompression bonding. For this reason, the occurrence frequency and amount of bleeds tend to be further increased. In some cases, bleed may even occur on the top surface of the semiconductor chip, and accordingly, there is a risk of electrical failure or wire bonding failure.
본 발명은 이러한 실정에 감안하여 이루어진 것으로, 열압착 시에 양호한 매립성을 가지면서 고온 가압 처리 시의 블리드량의 증가를 억제할 수 있는 열경화성 수지 조성물을 제공하는 것을 주된 목적으로 한다.The present invention has been made in view of such circumstances, and a main object is to provide a thermosetting resin composition capable of suppressing an increase in bleed amount during high-temperature pressurization while having good embedding properties during thermal compression bonding.

[블리드량 평가][Evaluation of bleed amount]
상기 매립성 평가에서 「A」 또는 「B」 평가였던 것에 관해서만 블리드량을 평가했다. 상기 매립성 평가에서 제작한 평가 샘플과 같은 수순으로 평가 샘플을 제작했다. 반도체 칩 A의 필름형 접착제와 반도체 칩 B의 반도체 웨이퍼를, 120℃, 0.20 MPa, 1.5초간의 조건으로 압착했다. 이어서, 가압 오븐을 이용하여, 140℃, 0.7 MPa, 30분의 조건으로 고온 가압 처리(가압 큐어)를 행하고, 가압 큐어 전후에 있어서, 평가 샘플을 현미경으로 관찰하여, 평가 샘플의 네 변의 중심으로부터 필름형 접착제의 블리드량(돌출량)을 각각 측정했다. 가압 큐어 전의 블리드량을 L1, 가압 큐어 후의 블리드량을 L2로 하여, 이하의 식에 기초하여, 블리드량 증가율을 산출했다. 결과를 표 1에 나타낸다. The bleed amount was evaluated only for those that were evaluated as "A" or "B" in the above embedding property evaluation. Evaluation samples were produced in the same procedure as the evaluation samples produced in the above embedding property evaluation. The film adhesive of semiconductor chip A and the semiconductor wafer of semiconductor chip B were crimped|bonded under the conditions of 120 degreeC, 0.20 MPa, and 1.5 second. Next, using a pressurized oven, a high-temperature pressure treatment (pressure cure) is performed under conditions of 140° C., 0.7 MPa, and 30 minutes, and before and after the pressure cure, the evaluation sample is observed with a microscope, from the center of the four sides of the evaluation sample. The bleed amount (protrusion amount) of the film adhesive was measured, respectively. The bleed amount before pressure curing was L1, and the bleed amount after pressure curing was L2, and the bleed amount increase rate was calculated based on the following formula.

표 1에 나타내는 것과 같이, 제1 엘라스토머 및 제2 엘라스토머를 함유하는 실시예 1∼7은, 제1 엘라스토머 또는 제2 엘라스토머의 어느 한쪽밖에 함유하지 않는 비교예 1∼3과 비교하여, 매립성이 우수하고, 고온 가압 처리 시의 블리드량 증가율도 낮았다. 이들 결과로부터, 본 발명에 따른 열경화성 수지 조성물이 열압착 시에 양호한 매립성을 가지면서 고온 가압 처리 시의 블리드량의 증가를 억제하는 것이 가능하다는 것이 확인되었다. As shown in Table 1, Examples 1 to 7 containing the first elastomer and the second elastomer have superior embedding properties compared to Comparative Examples 1 to 3 containing only either the first elastomer or the second elastomer. It was excellent, and the bleed amount increase rate at the time of the high-temperature pressure treatment was also low. From these results, it was confirmed that the thermosetting resin composition according to the present invention can suppress an increase in the amount of bleeding during high-temperature pressurization while having good embedding properties during thermal compression bonding.
이상의 결과와 같이, 본 발명에 따른 열경화성 수지 조성물은, 열압착 시에 양호한 매립성을 가지면서 고온 가압 처리 시의 블리드량의 증가를 억제할 수 있으므로, 열경화성 수지 조성물을 필름형으로 형성하여 이루어지는 필름형 접착제는, 칩 매립형 필름형 접착제인 FOD(필름 오버 다이) 또는 와이어 매립형 필름형 접착제인 FOW(필름 오버 와이어)로서 유용하게 될 수 있다. As a result of the above, since the thermosetting resin composition according to the present invention has good embedding properties during thermal compression bonding and can suppress an increase in the amount of bleed during high-temperature pressing treatment, a film obtained by forming the thermosetting resin composition into a film form The mold adhesive can be useful as FOD (Film Over Die), which is a chip-embedded film adhesive, or FOW (Film Over Wire), which is a wire-embedded film adhesive.
