The substances semiconductor manufacturing consumes, by class: what each one does, the process steps that use it, the grade terms the industry uses for it and whether anything else can do its job.
Each entry describes a class of material, never a supplier's product. Suppliers, supply concentration and the rules that restrict a material are read from the registers that hold them. The Hub holds no safety data sheet, handling instruction or exposure limit for any material. Use the supplier's own safety data sheet and the guidance of the relevant authority.
Listed by class, then by name. No place in this register can be bought. Inclusion, position, prominence and wording are not for sale, sponsorship, partnership or favour. The Hub records every request to buy one, with who asked and when, and refuses it. See also the conformance register.
The wafers devices are built on, from silicon to compound semiconductor and engineered substrates.
Process gases for deposition, etch, doping and purging, and the bulk gases a fab consumes continuously.
Filtering by process step, alternatives and supply concentration, and the register's coverage statement, are for registered members. Registration is free and takes a minute. You come back to this page afterwards.
