Reclaiming wafers helps our clients capture the full value of their silicon assets.

 

OUR RECLAIM



What IS RECLAIM

Silicon wafer reclaim is a multi-step process that is used to convert a used wafer into a functioning test wafer. These test wafers offer similar performance as a virgin test wafer at a much lower cost.

Why reclaim

Lower your cost. Reclaim is typically less than 1/3 to 1/4 the cost of new prime wafers and most wafers can be reclaimed several times for additional cost savings.

How Reclaim is used

The primary application for reclaim wafers is to diagnose process conditions of the equipment used in semiconductor manufacturing.

 

OUR EDGE


 

OUR PROCESS


Reclaim Wafer Process Flow.


RECEIVED

Order acceptance and documentation control takes place initially to ensure incoming spec review and to segregate wafer lots

Incoming SORT

The customer supplied wafers are inspected using various equipment. We verify that the mechanical properties of the wafers are suitable to achieve the clients finished specifications

STRIP & Etch

We use a chemical process to remove any existing materials from the surface of the wafers

POLISH

We use a two-step polish process beginning with removal of stock. This step focuses on surface planarization to remove scratches, pits and surface defects.

FINISH

Stage two of our polishing step is our finished polish. This is a minimum removal, final polish step that buffs the wafers and removes haze.

CLEAN

Our RCA clean uses a mixture of chemistries that include SC-1 and SC-2 processes.  We include a megasonic cleaning step to achieve reduced surface metals and particle contamination.

Final INSPECTION

A quality inspection is performed using automated metrology equipment and recorded for customer compliance.

PACKAGING/label & SHIP

Wafers are securely transferred into cleaned cassettes; the cassettes are double bagged and individually labeled.

certification

Tier I provides a Certificate of Conformance for each lot processed in our facility. A Certificate of Analysis is provided to validate the quality of the product.
