Definitions
- the present invention relates to a polymerizable composition containing an acid generator and a cationically polymerizable compound.
- the present invention relates to an adhesive composition, an adhesive for bonding, and an adhesive film using the same.
- the present invention also relates to a sealing composition and a sealing agent.
- the present invention relates to an optical waveguide forming material and an optical waveguide.
- Adhesives have traditionally been used for bonding semiconductor circuit wiring boards, such as ball grid arrays (BGA) or chip size packages (CSP), or tape automated bonding (TAB) tape and heat spreaders (heat sinks). Have been used in the past.
- the adhesive is used as a thermosetting liquid adhesive or an adhesive sheet.
- the semiconductor chip is heated at a high temperature for a long time when it is cured, a heat stress is applied to the semiconductor chip.
- the adhesive curing process required a long time.
- Japanese Patent Application Laid-Open No. 2001-131499 describes that an adhesive sheet is formed by heating at 150 ° C. for 2 hours in a curing step.
- thermosetting adhesives generally have poor storage stability at room temperature. Therefore, transportation and storage had to be performed at a low temperature. In addition, I had to use it in a single hour. In this way, there were defects in equipment, cost, and handling. Furthermore, if the curing temperature is set low in order to shorten the curing time of the adhesive, the storage stability deteriorates.
- the conventional thermosetting die bonding film has a large cure shrinkage during heat curing. Therefore, a plurality of semiconductor chips are stacked while being aligned through an uncured die bonding film to produce a laminate, and then the laminate is heated to cure the die bonding film and heat the semiconductor chip. When bonded, the stacked semiconductor chips tilted or the semiconductor chips themselves warped. As a result, the semiconductor chip In some cases, misalignment of the head occurred.
- Japanese Unexamined Patent Application Publication No. 2004-39992 discloses a photocurable die bonding film.
- sufficient adhesive properties have not been obtained, and further improvements are desired. That is, conventionally, an adhesive composition that has been cured with a small amount of active energy ray irradiation, has excellent cured product properties such as adhesion, and has excellent storage stability at room temperature has been desired. . Also, an adhesive or an adhesive film that can laminate and bond semiconductor elements in a parallel state has been desired.

For this reason, it is sealed with liquid grease and used in a state protected from the external environment.

Here, an underfill agent is used between the circuit board and the chip to reduce the stress.
- Sealants are also used in liquid crystal displays!
- liquid crystal is sealed between two parallel liquid crystal substrates, and a transparent electrode is laminated on the liquid crystal substrate.
- a sealing agent is used as a sealing material for sealing the liquid crystal.
- thermosetting epoxy resin has been used for the sealing material.
- such a thermosetting epoxy resin requires heating at a high temperature of 150 to 180 ° C for about 2 hours. For this reason, there was a problem with the 'productivity' not being improved!
- JP-A-11-199651 and JP-A-2000-191751 disclose the purpose of improving productivity and sealing a heat-sensitive substrate. so, An ultraviolet curable encapsulant composition is disclosed. However, the irradiation energy required for curing is large, and further improvement in productivity is desired.
- a sealing agent is used as a sealing material for bonding (sealing) a glass substrate constituting an element and an airtight container.
- EL elements There are two types of EL elements: inorganic EL elements and organic EL elements.
- Organic EL devices are superior to inorganic EL devices in terms of high brightness, high efficiency, high speed response, and multiple colors.
- the heat resistance of organic EL elements is low, and the heat resistance temperature is about 80-100 ° C. For this reason, there has been a problem in sealing an organic EL display that even if a thermosetting epoxy resin is used as a sealing material, it cannot be sufficiently heated and cured.
- 2004-231938 discloses a photo-curing type sealing material that can be cured at low temperature and high speed.
- a photo-curing type sealing material that can be cured at low temperature and high speed.
- the organic dye of the organic EL element deteriorates and the emission intensity becomes insufficient.
- the curability was still insufficient when irradiated with light having a wavelength of 350 nm or longer.
- Japanese Patent Application Laid-Open No. 2004-221405 describes that a light emitting diode is sealed with a grease.
- white LEDs are attracting attention as illumination light sources that can realize significant energy savings. For this reason, it is important to efficiently extract the light emitted from the light emitting diode element (LED chip). Therefore, there is a demand for non-colored and highly transparent sealants for LED chips.
- Still another polymerizable composition is a material for forming an optical waveguide.
- optical waveguides for example, basic components in optical devices, photoelectric integrated circuits (OEICs), and optical integrated circuits (optical ICs), etc. for realizing large-capacity information transmission such as movies and movies and optical computers Known as.
- Optical waveguides have been studied earnestly due to the large amount of demand, while products with particularly high performance and low cost are required.
- inorganic glass such as quartz has been used as this type of optical waveguide.
- Quartz-based optical waveguides have excellent properties such as heat resistance, low polarization dependence, low loss, and low temperature dependence.
- RIE Reactive Ion Etching
- high temperature processes including high temperature processes and RIE (Reactive Ion Etching) processes.
- optical waveguides using polymer materials have been proposed and are being put into practical use.
- High molecular weight materials are easier to process than inorganic materials, and can be easily increased in area and film.
- since it is flexible it has various advantages such as wide application and easy adjustment of the refractive index.
- ultraviolet curable resin is expected to be a material for optical waveguides because it is a material capable of mass production.
- the resist is exposed to UV (ultraviolet light) and developed to form a waveguide pattern.
- the portion not covered with the resist is removed by reactive ion etching. Thereafter, the resist that is no longer needed is removed.
- This RIE method is generally expensive because it includes a vacuum process and a resist process for reactive ion etching.
- minute vertical scratches are formed on the side surfaces of the core. This increases the scattering loss after fabrication of the optical waveguide.
- stamper method In the stamper method, a groove is formed in the clad, and then a resin is poured into the groove to form a core. Therefore, a significant cost reduction can be achieved. However, with the stamper method, sufficient waveguiding efficiency is not obtained due to the generation of voids and burrs during upper clad fabrication.
- a pattern is produced by irradiating an energy line such as direct light without a process of covering with a resist and then removing the unexposed portion by development. According to this method, the process becomes simpler than the RIE method, and the cost can be reduced.
- an optical waveguide can be produced simply by irradiating active energy rays such as light to provide a refractive index difference. This eliminates the photoresist coating process, reactive ion etching process, and development process. Therefore, it is a low-cost manufacturing method with excellent mass productivity, and the scattering loss due to the fluctuation of the side surface shape as seen in the RIE method or the stamper method can be suppressed.
- Active energy rays such as light irradiated by the direct exposure method and the photo bleaching method are various such as X-rays, ⁇ rays, j8 rays, ⁇ rays, ultraviolet rays, visible rays, infrared rays, and electron beams. Among these, it is most preferable to use ultraviolet rays from the viewpoint of having a certain energy level and a relatively inexpensive and compact irradiation apparatus.
