IC grade silicon wafers

Product Description

 Rocky Mt E Recovery was started to supply IC grade silicon wafers on a consistent and long term basis.  The company “purchased” advanced capabilities and knowledge.  The below assets were acquired from a well-known scrap silicon company, in business from ***6 to ***2:
• High tech silicon stripping equipment
• Custom automation
• Processing IP – chemical/mechanical recipes to strip whole wafers, broken wafers, blue tape, and solar broken silicon of patterns and color
• Progressive production systems
• *5 resistivity testing tools (includes non-contact, *-pt probe, *-pt probe, ADE automated tool)
• Database of IC supply contacts and diverse networks for IC grade Si supply
• Established contractual agreements with WW leading IC producers
• Retained original company owner/President to run operations and maintain relationships

Company Name:  Rocky Mt. E Recovery
Current Inventory:
*2" whole wafers:  ***0 kgs
  8" whole wafers:  ***0 kgs
  6" whole wafers:  ***0 kgs
2" to 5":  ***0 kgs
Broken silicon:  ***0 kgs
Blue tape:  ***0 kgs
Ingot tops/tails:  **0 kgs

Silicon Specification:

• **0% whole wafers - tested for resistivity
• whole wafers separated by resistivity - pattern - color
• IC grade
• *1N purity
• Mono crystalline
• Resistivity > 1 ohm cm squared - bulk resistance
• Average resistivity:  *5 ohm cm bulk
• Broken silicon: sold as percentage of resistivity content

***0 kgs of broken are bare, measuring *9% + high resistivity. 

The company is focused on precise, accurate, and honest silicon testing and labeling.  Inspections are WELCOME. 

Current price:  $*5/kg OR the best offer received.
