Description
Lot Assorted Silicon Wafers Broken & Whole w/ 30 Gal HDPE Tank 150 LBS
This is a bulk lot of assorted silicon wafers — a mix of broken pieces and whole wafers — stored in a 30-gallon HDPE tank. The lot weighs approximately 150 lbs in total. Wafers vary in diameter and show a range of thin-film process coatings, die grid patterns, and surface finishes visible in the photos. The lot is sold as-is with no sorting, testing, or inventory count performed.
Specifications & What's Included
- Material: Silicon (Si)
- Wafer condition: Mixed — broken fragments and whole wafers
- Wafer sizes: Assorted / multiple diameters (various sizes visible in photos)
- Wafer surface types: Various — thin-film coatings, iridescent process layers, die grid patterns observed
- One wafer visibly labeled "AL203" (likely alumina/sapphire substrate or process identifier)
- Approximate total lot weight: 150 lbs (wafers + tank)
- Container: 30-gallon HDPE (High-Density Polyethylene) tank
- Tank outer dimensions: 20 in diameter x 30 in tall

Applications
Silicon wafers are the foundational substrate used in semiconductor device fabrication. They are sliced from single-crystal silicon ingots and polished to precise tolerances before being processed into integrated circuits, solar cells, MEMS devices, and other microelectronic components. Whole or lightly damaged wafers from surplus lots like this are commonly acquired for university and industrial research, process development and calibration runs, materials science study, reclaim and recycling programs, and artistic or decorative use given their distinctive iridescent thin-film appearances. Broken wafer fragments are also used in secondary materials recovery, where the silicon is reclaimed for reprocessing. This type of bulk semiconductor scrap lot is typically sourced from fab decommissions, process yield-out material, or equipment cleanouts, and is of interest to researchers, materials buyers, reclaim processors, and collectors alike.
This lot of assorted silicon wafers — broken and whole — is sold as-is. The wafers are stored in a 30-gallon HDPE tank and have not been sorted, tested, or inventoried. The lot contains a mix of whole and broken wafers of varying diameters and process types, as visible in the photos. The HDPE tank shows surface clouding and general wear consistent with industrial use. One wafer visible in the photos is labeled "AL203." The lot is being sold as photographed with no guarantees on wafer counts, sizes, or material specifications. Please view our photo set and contact us if you have any questions.
