Can anyone list down the wafer and equipment leaders

Everyone talking of new processor being designed by so and so design house and new technology node manufacturing by so and so foundry
I would like to know more about supply chain to foundries. Who are leading suppliers of equipment and raw silicon wafer.
What is the so called technological development roadmap for this market?
 
One among Intel/Samsung/TSMC

First, we have to look who are going to be the 'fab owners'. As per an earlier research (image link given below), the last men standing are Intel/Samsung/TSMC. This is till 14 nm. As per a recent KPMG research, unless the end market is in few billion $, design cost may not be worth it. So whoever may the supplier of equipment or wafer, end customer can only be one among the three.

So can you name few of "whoever may be the supplier" and based on what parameters does these three foundries decide whom to chose as supplier
 
I think your question was, and correct me if I'm paraphrasing incorrectly: "Raw materials suppliers to foundries" and "Equipment suppliers to foundries".

Silicon is supplied by SUMCO and SunEdison. SOI (silicon on insulator) wafers are supplied by Soitec. Most foundries use either silicon or SOI, although silicon is currently much more dominant.

Silicon wafers are processed using chemicals. I'll use the chemical formulas for compactness. HF, H2SO4, HNO3, H2O2, NH4OH, HCl, KOH, IPA, CuSO4 are used in huge quantity and high purity forms. N2, Argon, NF3, NH3, WF6, and organometallics are some gas-phase chemicals. Solids include tantalum, copper, titanium, and tungsten.

Wet chemical manufacturers who supply foundries include KMG, Honeywell, Sumitomo Chemical, and Hitachi Chemical. Gas manufacturers who supply foundries include Air Products and Air Liquide. Metals manufacturers who supply foundries include Tosoh SMD and Cabot Corp.

The vendors who make equipment to spread the chemicals (solids, liquids, or gases) on silicon wafers are in two categories: Traditional and new. The traditional vendors are Applied Materials, Lam Research, and Tokyo Electron. The new vendors are fragmented, tightly controlled by one foundry and a single Asian country, and pursue a low-cost strategy.

The final equipment vendor I'll mention is ASML. This one is different. While other parts of the fab spread chemicals on silicon, ASML spreads light on photoresist, using proprietary techniques they invented and control. They have no competitors, and directly control the entire industry.
 
Yes benb you got my question right. Also nice that you pointed out chemicals also to be one of the raw materials.
Can you also mention what parameters(apart from cost and wafer diameter) does foundry look for when selecting the silicon supplier.
