Different Types of Chemicals Used in Electronic Industry
Transistors and resistors, and diodes and capacitors – when we think about the bulk of raw materials utilized at the factory floor of an electronic device manufacturing company, these are the things that come to our mind.
However, do you know that apart from these electronic components, the electronic industry also utilizes a bulk of different types of chemicals in the manufacturing and packaging process?
These chemicals are known as electronic chemicals, and they can exist in solid, liquid or gas form. Today, we will look at different types of electronic chemicals, that which every electronic device manufacturer uses in some capacity.
Chemicals Used in the Manufacturing of Silicon Wafers
Silicon wafers are thin slices of silicon crystals that are used in the fabrication of integrated circuits (ICs) and other semiconductor based micro devices. These wafers do not pre-exist in our environment; they are actually produced from silica (sand) and then processed further until they take final shape of a wafer.
In the manufacturing of silicon wafers, many chemicals are used. Some of these are listed below:
Hydrogen chloride, primarily used to remove impurities.
Ammonium chloride, which is used in the production of polysilicon crystals.
Ammonia, used in the production of monosilane, an active byproduct of silicon wafer manufacturing process.
Out of the total chemical consumption in electronic industry, chemicals used in the production of silicon wafers account for the largest share.
Chemicals Used in the Manufacturing of Photoresists
Photoresists are light sensitive materials, coated onto a silicon wafer, so as to serve as a supporting component for the following photolithography process. Every semi-conductor built electronic device, undergoes the process of photolithography.
These photoresist coatings are composed of a combination of film forming agents and light sensitive chemicals. The most commonly used film forming agents belong to the category of cresol novolac resins. As for the light sensitive chemicals, most manufacturers prefer using naphthoquinone diazides.
Wet Processing Chemicals
Wet processing chemicals are those chemicals that are used in different stages of semiconductor processing. These are solvents and etchants, and acids and bases. Some commonly used wet processing chemicals are:
Sulfuric acid
Iso-propyl alcohol
Ammonium-hydroxide
Nitric acid
Phosphoric acid
The consumption of wet processing chemicals in electronic industry is believed to be 6% of the total chemical consumption.
This brings us to the end of our list. We hope the provided information served as a valuable resource for you and helped you understand how different types of chemicals are being used in the electronic industry.
