What Are The Benefits Of the Interposer Board?
Generally, an interposer can be used to build an interface that can support obsolete components on a legacy board that cannot be redesigned.
Basing on the different types of interposer technologies, the following are also some of their specific benefits;
The interposers can be used in applications that are of high performance with devices that are single stacked which allow great thermal dissipation.
Dies can be created by a single source thus there is no need to outsource to third party suppliers.
The transistors in the interposer do not require to be large since they are not driving wire bonds to on board connections.
There is a heat build-up that is normally experienced in full 3D-IC designs, here, the heat can be avoided or minimized.
There is reduced requirements of ESD protection for the die to die connection through the interposer.
Requalification of process is eliminated as each die can be manufactured at a node that is proven without a TSV through an active silicon.
Glass interposers are double fold in that they promise a greater interconnection density as compared to the other counterparts, organic interposers.
They are less costly as compared to the silicon interposers hence they are having an interconnect density that is similar.
Therefore, the glass interposers are ideal to be used in the ultra-high pitch applications like in network and signal processing unit, in communications and high performance computing.
Due to their well-established supply chain, organic interposers are considered to be cheaper.
Also, the organic interposers can be manufactured using traditional process like the wet etching process.
Where Can You Use Interposer Board?

They are used in high bandwidth memories.
They are used in multi-chip modules.
Also, they are used in BGA packages.
Are There Limitations Of Interposer Board?
Specific interposer technologies have their distinct limitations as discussed below;
Silicon Interposer Boards
Firstly, silicon interposer boards are very expensive in their processing since electrical insulation should be done around via walls.
Cost is the major challenge of having the silicon interposer boards due to their complexity when it comes to processing.
The cost of process silicon interposer chips ranges from $30 to up to over $100 in connecting multiple reticles for chips that are larger.
Secondly, the silicon interposer boards are limited in size from where they originate by the silicon wafer.
Thirdly, signal loses are experienced due to dielectric and conductor losses.
Lastly, they need an organic BGA package between the system board and interposer.
During manufacturing, defects of the surface that might lead to cracking are witnessed on the glass interposer boards.
Glass interposer boards have a lower thermal conductivity as compared to the silicon interposer boards.
Also, there is a limitation on the diameter achievability.
Flexibility issues due to their mechanical properties thus it becomes difficult in the attachment of another die on the interposer.
Organic interposers have lower finer pitch density as compared to glass and silicon interposers.
What Is The Function Of Interposer Board?

Which Substrates Should You Use For Interposer Board?
Substrates are essential parts that equip the package with a full mechanical support base hence forming an electrical interface.
The electrical interface allows the external world to have an access to the device housed within the package.
For the interposer board, organic and inorganic substrates including other materials can be used, the following are some of the substrates used.
This is a thermoset plastic laminate that is versatile and has a high pressure with a good strength to weight ratios.
Since it has very minimal close to zero resistance to water, its used as an electrical insulator as it possesses mechanical strengths that are considerable.
Both in dry and humid condition s, the material is able to retain its qualities of electrical insulation and mechanical values.

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 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.
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.
