| arsenic |
atomic symbol, As, arsenic is the 33rd element in the periodic table (atomic number 33) with an atomic weight of 74.9. Arsenic is a group V element making it a donor in silicon, ie, makes silicon N-type. Arsenic has the same atomic diameter as silicon and so introduces very little strain into a silicon crystal lattice. Arsenic has a relatively low diffusivity and is widely used to create shallow doped junctions such as source/drains. Arsenic is toxic and carcinogenic.

| arsine |
chemical formula AsH 3 , arsine is a highly toxic gas with a garlic like odor and a TLV of 0.05ppm. Arsine is flammable in the range of 4.5 - 78%. Arsine is so toxic that is has been used as a chemical warfare agent. Arsine is used as a dopant gas during various CVD reactions and to create As+ ions for ion implantation.

| arsenic |
An N-type dopant often used to form the buried layer in a bipolar structure. Also used as an implant source in both bipolar and MOS processing. This element has both metallic and non-metallic properties and hence is frequently referred to as a metalloid. Because of its metalloid properties arsenic can be in compounds both in the anionic and the cationic form. Arsenic is extremely poisonous to human beings and to other living beings.
