Probe Test Technician

Safran DSI•Camarillo, CA

1d•Onsite

About The Position

The Probe Test Technician performs electrical probe testing on full wafers and singulated semiconductor devices, including custom read-out integrated circuits (ROICs), other integrated circuits, and infrared detector arrays. This role sets up and operates manual and semi-automatic probe stations, aligns and maintains probe cards and needle probes, and executes established test programs and procedures to collect, log, and report electrical data. Working in a cleanroom environment under strict contamination-control and ESD discipline, the Probe Test Technician generates wafer maps and yield data used by process, test, and design engineering, and supports the engineering team in troubleshooting fixturing, contact, and equipment issues. This is a hands-on role with direct influence on yield visibility and product quality.

Requirements

High school diploma required; Associate's degree or technical certificate in electronics, engineering technology, semiconductor manufacturing, or related field preferred
3+ years of semiconductor probe test, wafer test, or electronics test technician experience preferred; equivalent military electronics/instrumentation experience considered
Hands-on experience operating wafer probe stations and performing electrical probe test in semiconductor manufacturing, R&D, or test environment
Working knowledge of basic electrical measurement principles and instrumentation (voltage, current, resistance, capacitance, I-V characterization)
Demonstrated fine motor dexterity, including microscope-based probe tip alignment and handling of small, fragile parts
Proven care and discipline in wafer/die handling, including cleanroom protocol and ESD control
Ability to follow detailed written procedures precisely and record data accurately and legibly
Ability to work independently on routine tasks after training, and collaboratively on non-routine work
Ability to use probe station and test instrument software and data acquisition interfaces, including file organization, data export, and basic spreadsheet analysis
Familiarity with ERP/MES transactions for lot tracking and test record entry
Requires U.S. Citizenship or Permanent Resident Status required.

Nice To Haves

3+ years of semiconductor test experience, with strong attention to detail and judgment to stop and escalate when results or equipment behavior look off
Experience probing infrared detector arrays, photodiodes, or other photonic/optoelectronic devices
Familiarity with ROIC or mixed-signal IC test, including digital I/O and pattern-based functional test
Familiarity with FPA, ROIC, and infrared detector architectures (e.g., InGaAs, SWIR, eSWIR, MWIR)
Experience with semi-automatic or automatic probers and probe card handling/planarization
Experience with semiconductor parameter analyzers (e.g., Keysight/Agilent B1500-class) and associated software
Familiarity with SPC concepts, yield analysis, and wafer map interpretation
Experience within an AS9100 or ISO 9001 quality system
Ability to obtain and maintain a U.S. Government security clearance
Works well in a fast-paced team environment; able to complete tasks with minimal supervision
Experience working in an ITAR environment
