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

Electronic and electrical products contain a number of hazardous substances, including lead, mercury and other metals, flame retardants and certain phthalates. These hazardous substances can impact human health and the environment through all stages of the life-cycle: During material extraction and manufacturing, workers and their surrounding communities may come into direct contact with hazardous chemicals which can result in significant adverse effects, including high cancer rates.

During the use phase of a product, hazardous chemicals may be released from electronics and lead to exposure of consumers and the environment. Further downstream, hazardous chemicals can be released from e-waste during disposal and recycling, directly affecting workers and entering ecosystems by contaminating the air, water and soil and entering food chains (Global Chemicals Outlook II). While informal e-waste operations are among the world&#;s most hazardous occupations, exposure to toxic substances is common even in formalized e-waste recycling in developed countries (Global Chemicals Outlook II).

The consumer electronic market continues to grow rapidly, and it has been estimated that the global electronic chemical and materials marked will grow from 22 billion USD in to 30.5 billion USD by (Global Chemicals Outlook II).

In light of these considerations, hazardous chemicals in electronics and electrical products have been a priority sector within the work on chemicals in products by the Strategic Approach on Chemicals Management (SAICM). A current project aims at accelerating the adoption of measures by governments and value chain stakeholders to reduce the use of chemicals of concern in electronics products.

The United Nations Industrial Development Organization (UNIDO) has been working with the secretariats of the Basel, Rotterdam and Stockholm Conventions and UNEP International Environmental Technology Centre to lead activities in this area to date. ICCM3 endorsed the addition to the Global Plan of Action of new activities related to hazardous substances within the life cycle of electrical and electronic products, including the work areas of e-products green design, environmentally sound manufacturing of e-products and awareness-raising for e-products.

In addition, ICCM3 agreed to continue to work to identify, compile and create an international set of best practice resources on topics in this area, drawing on existing initiatives and opportunities for collaboration within the Strategic Approach and with other international forums.
