Which Types Of Interposer Technologies Are There?


This specific type of interposer played a vital role in the integration of the 2.5 and 3D IC chips since they do contain a fine pitch density and a capability of TSV formation.

For it being technologically proven, it is used commercially in high performance computing systems.

The high performing computing systems have the logic and memory heterogeneous integrations that are established within the same platform.

The silicon interposer technology has its limitations that can be attributed to TSV profiles and microfluidic thermal design changes that are to mitigate the thermal issues.

One of the disadvantages of using this type of technology in the market is the cost factor of the interposer.

The present costs of the silicon interposers are so high hence it becomes difficult to support these high performance systems.

For a medium silicon interposer chip, it goes close to $30 while to put together reticles for a larger chip can go for more than $100.

For this specific reason, silicon interposer applications of high speed networking and server chips have been limited.

To explore many opportunities while using the silicon interposer technology, the cost levels need to be considered and be lowered.

Glass Interposers

Glass interposers have a benefit of being double fold thus they do provide an interconnect density that is high than the organic interposers.

Their cost of production is also another important fact as they are less costly than the silicon interposers but they provide the same interconnect density.

A higher interconnect density makes the glass interposers to be applied in applications of ultra-high pitch density like network and signal processing and testing.

Also, they can be used in computing of higher performance like opto-electronics based computing, in communications and frequency of the radio.

Moreover, they are also applied in the applications of low cost packaging like the sensor power, micro electro systems among other devices.

Despite the glass interposers being available at a lower cost, they have a great achievement in the demonstration of high and quality yields.

Like the silicon interposers, glass interposers also have their limitations when being adapted for different uses and also in their manufacturing.

During their manufacture, the glass interposers face a great challenge of surface defects that might lead them to crack.

Additionally, the glass interposers also have a thermal conductivity that is low as compared to the silicon interposers hence they cannot be used in some applications.

Furthermore, there is a challenge in the effective achievability of diameter for the glass interposers.

Therefore, to improve the glass interposers, more research should be conducted in areas like techniques for etching for TGV improvements, polymer utilization and metallization in realizing applications of high performance.

Research should also be done in panel based cost approaches, techniques which provide interconnections that are lateral for the redistribution layers and much more.

Through that, a viable and a commercial glass interposer will be created that is going to realize most needed cost benefits in the industries.

Organische Interposer

The organic interposers is part of the interposer technologies that is explored in the realizing the benefits of cost among the technologies of interposer.

The organic interposers have proven to cheaper because they have a supply chain that is well established.

On that note, they also have the ability of getting manufactured through traditional process like the wet etching process.

Organic interposers like other interposer technologies also have their challenges, the main challenge here being in their mechanical properties, the interposers are not flexible.

The inflexibility makes it hard for the chips to get attached on the interposers.

The organic interposers also have a lower finer pitch density than the glass interposers and the silicon interposer.

At the moment, organic interposers are mostly applied and used in large central processing units and the graphics processing units.

Also, the organic interposers are also being used in integration of logic memory and other types of application specific integrated chips.

Some of the RF higher performances have been put into demonstrations using these type of interposers.
