The semiconductor chip bonding report analyzes emerging technologies, innovative solutions in the area of sub-micron die bonders. The chip bonding report also sheds light on key players, startups and market trends.
Die Bonding is the process of attaching the semiconductor die (or chip) either to its package or to some substrate. The process was originally introduced commercially by IBM in the 1960s for individual transistors and diodes packaged for use in their mainframe systems.
The Chip Bonding Report explain the process to accomplish die attach by using one of the following processes:
- Epoxy Die Bonding
- UV Die Bonding
- Solder Paste Die Bonding
- Eutectic Die Bonding
- Silver Sintering Die Bonding
- Thermocompression Die Bonding
Challenges
In this section of the Chip Bonding Report the challenges and their viable solutions have been discussed:
- Poor thermal conductivity aging resistance of gluing, and pollution caused by flux residue.
- Laser bonding requires coating the endothermic agent on the bonding surface of the substrate and the cover sheet which results in uneven heating causing chip warpage.
- Uneven heating causing chip warpage.
- High-temperature performance.
- Low-cost and eco-friendly die attach process for high temperatures.
- 3D microscale metal parts with high throughput.
- Bulky cooling radiation shielding to prevent degradation during operation.
Viable Solutions
Post comprehensive analysis Signicent’s expert came across the following viable, innovative, and possibly the finest solutions:
- The beneficial effect of the utility model is that the utility model can use the high-frequency vibration of the ultrasonic soldering iron to remove the characteristics of the oxide film, integrate the ultrasonic soldering iron, the chip automatic positioning patch, and the cooling process, which improves the production efficiency and soldering quality, and improves the chip’s performance.
- Automatic PMMA microfluidic chip solvent bonding device requires less time for bonding, hardly affects the chip shape and light transmittance, has good biocompatibility, high bonding strength, mild bonding conditions, and does not block the fine flow channel.
Hillocks generation on Al sheet surface
Since the Al sheet has low cost and excellent properties, such as thermal conductivity (237 W/(m·K)), electric resistivity (28.2 nΩ·m), and thermal stability, this die-attach bonding technology is an attractive alternative for wide band-gap devices that require high-temperature performance.
Ag/Sn/Ag sandwich structure
Reliable low-temperature die attach process Pb-based and Au-based systems have been used as conventional die-attach materials for high-temperature devices. However, these materials exhibit environmental problems and are expensive.
A die attach process using the backside metal of the Ag/Sn/Ag sandwich structure has been successfully developed for the mass production of Si devices.
- It has a low-temperature bonding process (235 °C),
- A high remelting temperature (above 400 °C),
- Rapid bonding time (20 ms), and
- It exhibits better properties than Au-12Ge and Pb-10Sn backside metals,
Ultrasonic Soldering Iron
The beneficial effect of the utility model is that the utility model can use the high-frequency vibration of the ultrasonic soldering iron to remove the characteristics of the oxide film, integrate the ultrasonic soldering iron, the chip automatic positioning patch, and the cooling process, which improves the production efficiency and soldering quality, and improves the chip’s performance.
Automatic PMMA microfluidic chip solvent bonding device
An automatic PMMA microfluidic chip solvent bonding device includes a container, a lifting and bonding mechanism, a heating device, a translation mechanism, and an electromagnetic chip holder. The automatic PMMA microfluidic chip solvent bonding device requires less time for bonding, hardly affects the chip shape and light transmittance, has good biocompatibility, high bonding strength, mild bonding conditions, and does not block the fine flow channel.
Alumina Ceramic Substrates and Gold Conductors
An alumina paste material comprising aluminum dihydric phosphate and alumina powder was developed for high-temperature electronic packaging. Alumina ceramic substrates and gold conductors on alumina were evaluated for electrical and mechanical performance. The most promising die-attach materials were found to be thick-film gold and alumina-based ceramic pastes. Alumina, sapphire, silicon, and silicon carbide dice were attached to the alumina substrates using these die-attach materials and exposed to the Venusian condition for 244 hours.
MRSI-S-HVM die bonder
The MRSI-S-HVM includes two modes of accuracies – 0.5 micrometers and 1.5 micrometers. The 0.5-micrometer mode uses a real-time alignment mechanism facilitated by the on-axis z-force bonding for the best possible co-planarity and final accuracy. For flip-chip bonding, it aligns the features on the bonding surfaces of the die and the carrier. The MRSI-S-HVM die bonder is capable of a chip-on-wafer (CoW) process with dies from the III-V wafer being picked, placed, and bonded onto a silicon wafer (12 inches) including fine lateral motions. It can also be applied to chip-on-interposer (CoI) and chip-on-substrate (CoS).

High-Power Blue WBC Technology
Panasonic Corporation announced it has succeeded in demonstrating the world’s highest brightness blue laser. This has been achieved by using the wavelength beam combining (WBC) technology on a direct diode laser (DDL) to produce a high-quality output beam.
This WBC technology combines the beams from multiple emitters at different wavelengths that are incident on the diffraction grating at angles corresponding to each wavelength. The resonator is then formed in between the shared partially transparent mirror and each edge face of the emitters.
