Foresite Standard Project Information
Have questions about what to expect when you work with Foresite? Here are more details about typical project engagements.
Final Report Deliverables
Final report deliverables include:
Specific project goal – Defined at time of quote
Client specifications – Cleanliness levels, SIR
Foresite test protocol to accomplish the project goal
Process background information, including the process sequence (defined by client) and a material matrix indicating fluxes and chemistries used in the process
Photo documentation of the areas investigated
Residue analysis data (if applicable) – Identification and concentration of any residues present
Electrical performance data (if applicable) – From specified tests
Education regarding the usual sources of the specific ionic and organic residues found
Foresite cleanliness limit recommendation for each identified ionic and organic species; Foresite cleanliness limits derive from 22+ years of failure analysis and process qualification experience
Foresite data interpretation and conclusions from our technical team
Failure mechanism scenario (if applicable) – What caused the failure to occur
Foresite recommendations for any process corrective action or optimization
Project report electronically sent to the client project contact
Telephone support available for discussion of the report
Note: One-page reports are issued for specific types of projects; these typically include cleaning projects and IC testing of C3 vial samples.
Upon the completion of the project, samples are either destroyed or returned to the client, per instructions.
Project Start Requirements
Requirements are:
Receipt of the samples
Establishment of the payment method (hard copy purchase order or credit card information)
Project Timing Options
Ion Chromatography (IC) Testing
Standard – Final report completion ten business days after the project start
Moderate Turn – Final report completion five business days after the project start
Fast Turn – Final report completion two business days after the project start (to analyze up to 50 samples) or three business days after the project start (to analyze 50-100 samples)
Cross-sectioning, SIR Testing and Cleaning
Project timing is established at the project start – Dependent upon factors such as equipment availability
Materials and Process Specifications
To analyze process performance, the materials and process specifications must be identified:
