Description
Technical Field
The present invention relates to a resin composition, a cured product, and a semiconductor device.
Background
In general, a semiconductor device for a semiconductor apparatus is manufactured by bonding a semiconductor element such as a semiconductor chip to a supporting member such as a lead frame by an adhesive (die bonding material). Conventionally, as an adhesive for a semiconductor, a gold-silicon eutectic, a solder, a paste-like resin composition, or the like is known, but in recent years, a paste-like resin composition has been widely used from the viewpoints of operability and cost.
With the high integration and miniaturization of semiconductor elements, conductive fillers are sometimes used as constituent materials of resin compositions used as die bonding materials from the viewpoint of improving the characteristics of the semiconductor device such as electrical conductivity and thermal conductivity. As the conductive filler, silver particles may be used from the viewpoint of high oxidation resistance or the like (for example, refer to patent document 1 below).

Disclosure of Invention
Technical problem to be solved by the invention
When the semiconductor element is disposed on the adhesive layer after the adhesive layer containing the resin composition is formed on the support member, a rounded portion (fillets) which is warped in the stacking direction of the semiconductor element and the support member tends to be formed on the outer peripheral portion of the adhesive layer. When the rounded portion is formed on the outer peripheral portion of the adhesive layer, the stress relaxation effect is excellent, and peeling between the semiconductor element and the support member is easily suppressed.
Here, since silver is an expensive material, it is desirable to use other inexpensive metals as the conductive filler, and it is considered to use aluminum particles which are inexpensive and excellent in electrical conductivity, thermal conductivity, and the like. According to the findings of the present inventors, in the case of using silver particles alone as the conductive filler, the rounded portions were formed appropriately on the outer peripheral portion of the adhesive layer, whereas in the case of using aluminum particles as the conductive filler, a phenomenon (rounded portion defect) was confirmed in which the rounded portions were broken on the outer peripheral portion of the adhesive layer. Therefore, in the case of using aluminum particles as the conductive filler, it is required to suppress the chipping of the rounded portion.
The purpose of the present invention is to provide a resin composition capable of suppressing the defects of a fillet while using aluminum particles, and a cured product thereof. The present invention aims to provide a semiconductor device using the resin composition or a cured product thereof.

The resin composition according to embodiment 1 of the present invention contains (a) metal particles, (B) alkoxysilane, and (C) a thermosetting component, wherein the (a) component contains aluminum-containing particles, and the (B) component contains alkylalkoxysilane. The resin composition according to embodiment 2 of the present invention contains (a) metal particles, (B) alkoxysilane, and (C) a thermosetting component, wherein the (a) component contains aluminum-containing particles, and the (B) component contains alkoxysilane having 2 or more silicon atoms. A cured product according to another embodiment of the present invention is a cured product of the above resin composition.
According to the resin composition and the cured product thereof, the defects of the rounded portions can be suppressed while using aluminum particles. This makes it possible to suppress peeling between the semiconductor element and the support member, while exhibiting a good stress relaxation effect.
A semiconductor device according to another embodiment of the present invention includes a support member, a semiconductor element, and an adhesive layer disposed between the support member and the semiconductor element, wherein the adhesive layer contains the resin composition or a cured product thereof.

Hereinafter, embodiments of the present invention will be described in detail. However, the present invention is not limited to the following embodiments, and can be implemented by various modifications within the scope of the gist thereof.
< resin composition and cured product >
The resin composition according to the present embodiment (embodiment 1 and embodiment 2, hereinafter the same) contains (a) metal particles (hereinafter referred to as "(a) component" as the case may be ". Metal-containing particles, for example, metal powder), (B) alkoxysilane (hereinafter referred to as" (B) component "as the case may be") and (C) a thermosetting component (hereinafter referred to as "(C) component"), (a) contains (a) 1 st particles containing aluminum (aluminum particles. Hereinafter referred to as "(A1) component" as the case may be ". For example, aluminum powder). In embodiment 1, the component (B) contains (B1) alkylalkoxysilane (hereinafter, referred to as "(B1) component", as the case may be). In embodiment 2, the component (B) contains (B2) an alkoxysilane having 2 or more silicon atoms (hereinafter, referred to as "(B2 component", as the case may be ").
The resin composition according to the present embodiment is a conductive composition, and can be used as a resin composition for bonding a semiconductor element to a support member. The resin composition according to the present embodiment is a curable (e.g., thermosetting) composition. The resin composition according to the present embodiment can be used as a paste-like resin composition. The cured product according to the present embodiment is a cured product of the resin composition according to the present embodiment.
According to the resin composition and the cured product thereof according to the present embodiment, the defects of the rounded portions can be suppressed while using aluminum particles. This makes it possible to suppress peeling between the semiconductor element and the support member, while exhibiting a good stress relaxation effect. The reason why the defect of the rounded portion can be suppressed by using the resin composition and the cured product thereof according to the present embodiment is not clear, but the present inventors speculate as follows. However, the reason is not limited to the following. That is, when the dispersibility of the metal particles in the resin component or the affinity of the resin composition with respect to the support member is low, chipping of the rounded portions occurs. On the other hand, in the present embodiment, the (B1) component or the (B2) component is bonded to the (a) component or the support member via the silicon atom of the alkoxysilane, whereby the dispersibility of the (a) component in the (C) component and the affinity of the resin composition with respect to the support member are improved (it is presumed that the alkyl group of the (B1) component and the 2 or more silicon atoms of the (B2) component contribute to the bonding of the (B1) component and the (B2) component to the (a) component or the support member). Therefore, the component (a) is inhibited from separating from other components during the flow of the resin composition, and hence the defect of the rounded portion is inhibited.

For this reason, according to the findings of the present inventors, it is presumed that the above-described problem occurs due to a "rising phenomenon" (phenomenon in which the resin composition reaches the upper surface of the semiconductor element) in which the resin composition extends to the upper surface side of the semiconductor element due to a capillary phenomenon or the like on the side surface of the semiconductor element. In contrast, in the present embodiment, when the resin composition contains a polyoxyalkylene compound, the rising phenomenon can be suppressed. The following can be presumed: since the polyoxyalkylene compound has high affinity for the component (a) and the component (C), the use of the polyoxyalkylene compound improves the dispersibility of the component (a) in the component (C) and the like, and thus the ascending phenomenon can be suppressed. Fig. 1 (a) is a diagram showing an example of the climbing phenomenon. By using a polyoxyalkylene compound, as shown in FIG. 1 (b), the climbing phenomenon can be suppressed.
The content of the polyoxyalkylene compound is preferably in the following range based on the total amount of the resin composition. The content of the polyoxyalkylene compound is preferably 0.1 mass% or more, more preferably 0.3 mass% or more, further preferably 0.5 mass% or more, particularly preferably 0.7 mass% or more, and most preferably 0.9 mass% or more, from the viewpoint of easily suppressing the climbing phenomenon. The content of the polyoxyalkylene compound is preferably 5 mass% or less, more preferably 3 mass% or less, further preferably 2 mass% or less, particularly preferably 1.5 mass% or less, and most preferably 1 mass% or less, from the viewpoint of easily securing the curability of the resin composition sufficiently. From these viewpoints, the content of the polyoxyalkylene compound is preferably 0.1 to 5 mass%.
(other Components)
The resin composition according to the present embodiment may contain other additives different from the above components. Examples of the additives include fatty acids (oleic acid, stearic acid, lauric acid, etc.), coupling agents (titanate-based coupling agents, aluminum-based coupling agents, zirconate-based coupling agents, zircoaluminate-based coupling agents, etc.), moisture absorbing agents (calcium oxide, magnesium oxide, etc.), wettability improvers (fluorine-based surfactants, nonionic surfactants, higher fatty acids, etc.), antifoaming agents (silicone oils, etc.), ion capturing agents (inorganic ion exchangers, etc.), and the like.
The use of fatty acids can suppress the above-mentioned climbing phenomenon similarly to the polyoxyalkylene compound. As the fatty acid, at least one of a saturated fatty acid and an unsaturated fatty acid can be used. The number of carbon atoms of the fatty acid is preferably 6 or more, more preferably 9 or more, and still more preferably 12 or more, from the viewpoint of easily suppressing the climbing phenomenon. The number of carbon atoms of the fatty acid may be 15 or more, or 18 or more. The number of carbon atoms of the fatty acid is preferably 24 or less, more preferably 21 or less, and even more preferably 18 or less, from the viewpoint of easily suppressing the climbing phenomenon. The number of carbon atoms of the fatty acid may be 15 or less, or may be 12 or less. From the viewpoint of easily suppressing the climbing phenomenon, the fatty acid preferably contains at least one selected from the group consisting of oleic acid, stearic acid, and lauric acid.
