Chip Wet Decapsulation: An Insight Into the Process

The Basics of Chip Wet Decapsulation

Chip wet decapsulation is a process of removing the layers of a chip to access internal components. It is an essential technique used to resolve technical issues that arise within electronic devices, particularly chips. This process requires the use of several chemical agents that can dissolve the protective layers that surround the chip without damaging the components inside. The process is widely used by engineers to investigate chip layouts, improve device performance and identify the root cause of device failures.

The Step-by-Step Process

The process of chip wet decapsulation involves several crucial steps. First, the chip is subjected to a pre-decapping process to remove the adhesive layer and wires from the surface. The chip is then transferred to a decapsulation solution contained in a container designed to hold the chip without direct contact with the solution. The container is then stored in an oven set to a specific temperature that complements the decapsulation solution being used. The solution slowly dissolves each layer of the chip, typically starting from the upper layers, allowing access to the underlying layers until all layers are removed.

The Role of Chemical Agents in Chip Wet Decapsulation

The chemical agents used in chip wet decapsulation play a significant role in the success of the process. The agents are intended to dissolve each layer selectively and without harming the underlying components of the chip. Hydrofluoric Acid (HF) is commonly used to dissolve the silicon dioxide (SiO2) layer on top of the chip. It is a highly corrosive and dangerous acid that requires careful handling by trained professionals. Nitric Acid (HNO3) is another chemical agent that is used to oxidize and dissolve the metal layers of the chip. The action of Nitric Acid dissolves the metal and removes it from the surface of the chip without affecting the underlying components.

Best Practices in Chip Wet Decapsulation

Chip wet decapsulation involves a detailed process that requires expertise and diligence to ensure the process is successful. The following are the best practices to maximize the success of the process:

  • Use the right decapsulation process that suits the type of chip being decapped without damaging any of the components contained within.
  • Ensure that the equipment used in the decapsulation process is cleaned and properly maintained to avoid contamination of the decapsulation solution used.
  • Handle the decapsulation agents with utmost care, as they are highly corrosive and can cause severe burns and injuries when mishandled.
  • Employ chemical and safety measures to mitigate the risks of chemical exposure or inhalation that may result in serious health problems.
  • Ultimately, the success of the chip wet decapsulation process relies on the experience and expertise of the professionals handling the process. The process must be approached with care, attention to detail, and respect for the chemicals used in the process.
