Cut crystalline mucocrystalline monolithic film and the pressure sensitive adhesive film used

Semiconductor devices are manufactured by the following processes. First, the crystal cutting process was implemented in the state of wafer attached with pressure-sensitive adhesive film for crystal cutting. Then, mounting, pickup, mounting, diebonding, and so on. In the manufacturing process of a semiconductor device, a film called a cut-crystal mucous monolayer is used.

The film has a structure consisting, in turn, of a substrate layer, a pressure-sensitive adhesive layer, and an adhesive layer, for example, as used in the following. First, the wafer is attached to the surface of the adhesive layer side and the wafer is cut while the wafer is fixed by dicingring.

Thus, the wafer is monolithic into a large number of chips (chips). Then, after the adhesive force relative to the pressure sensitive adhesive layer was reduced by irradiating ultraviolet light on the pressure sensitive adhesive layer, the adhesive sheet formed from the chip together with the adhesive layer was picked up from the pressure sensitive adhesive layer. After that, a semiconductor device is made by installing the chip on the substrate through a adhesive sheet.

Acrylic pressure sensitive adhesive

In addition, the layer containing the chip obtained through the crystal cutting process and the adhesive sheet attached to the chip is called the grain adhesion film (DAF).

As mentioned above, the pressure sensitive adhesive layer (crystal cutting film) which is weakened by ultraviolet radiation is called ultraviolet (UV) curing type. In contrast, in the manufacturing process of semiconductor devices, the pressure sensitive adhesive layer is not exposed to ultraviolet light and the adhesive relay remains constant, which is called pressure sensitive.

However, the film used in the manufacturing process of semiconductor devices requires antistatic property. A sheet for semiconductor processing has a pressure sensitive adhesive layer solidified by irradiating an energy line.

The pressure sensitive adhesive composition comprises a polymer having quaternary ammonium salt (antistatic agent) and an energy line curable basis, and an energy line curable pressure sensitive adhesive component (except the polymer). According to the semiconductor processing sheet, it can play excellent antistatic property and can inhibit the contamination of adhesive (wafer or chip) during stripping.

In the field of pressure sensitive adhesives, poly (methyl) acrylate is a very useful base material

In areas such as the pressure-sensitive adhesives widely used in tape, poly(methyl) acrylates have proved to be very useful as base materials. They show excellent properties such as tolerance to light, climate and a variety of chemicals, as well as in their inherent adhesion and their resistance to aging and heat. In addition, they can be used in multiple polar and less polar substrates, such as glass and steel, but also in polystyrene and polycarbonate.

There is a fundamental interest in improving the bonding properties of poly(methyl) acrylate based compositions, especially for substrates with less polarity, in order to be able to benefit from the numerous other positive properties of these substances under this type of bonding. In this regard, the further development of suitable adhesive resins is of particular interest. Adhesive resins based on low molecular weight poly(methyl) acrylates are described in particular in prior art.

The use of pressure-sensitive adhesive tape

As the use of pressure-sensitive adhesive tape has expanded over the years, performance requirements have become increasingly demanding.

Adhesives have been used for a variety of marking, securing, protecting, sealing and masking purposes. Adhesive tape generally includes a backing or base and adhesive.
Pressure sensitive adhesives (PSA) are well known to general technicians in the field and have certain characteristics including: (1) strong and permanent adhesion, (2) adhesion at no more than finger pressure, (3) sufficient retention to the adhesive body, and (4) sufficient cohesion strength.

Water Based Acrylic Pressure Sensitive Adhesive

Materials that have been found to work well as pressure-sensitive adhesives are polymers that have been designed and formulated to exhibit the desired viscoelastic properties, resulting in the desired balance of viscosity, peel adhesion, and shear strength. The most common polymers used to prepare pressure-sensitive adhesives are various (methyl) acrylate copolymers, natural rubber, synthetic rubber, and siloxane. As the use of pressure-sensitive adhesive tapes has expanded over the years, performance requirements have become increasingly demanding. For example, in terms of operating temperature and load, the shear holding capacity that was expected to support moderate loads at room temperature has been substantially increased for many applications.

In fact, many specific applications require pressure-sensitive adhesives to support loads under high stress conditions, such as, for example, exposure to intense weathering conditions or under intense use during which pressure-sensitive adhesive tapes are subjected to high mechanical and/or chemical stresses.

Pressure Sensitive Adhesive Tapes

When used for outdoor or external applications, pressure sensitive adhesive tape must be in a variety of challenging conditions such as exposure to the wide temperature range with maneuverability, and specifically in extreme temperature, such as for example in up to 40 ℃ 90 ℃ high temperature or low to provide acceptable performance under low temperature. Other challenging conditions in the context of this disclosure include exposure to strong winds or heavy rain, which can often occur in transportation and construction market applications.

In modern transportation and construction market applications, the need to reduce the weight of components has led to the increasing use of composite and thermoplastic materials, which are known to be challenging substrates for adhesives to bond to. In the motor vehicle and aerospace manufacturing industries, numerous external components are actually made from so-called LSE and MSE materials (i.e., substrates with low and medium surface energies, respectively).
