Wafer Laser Resistor and Functional Trimming System
The AOGEO wafer laser trimming system combines localized laser removal with electrical measurement to adjust designed resistor regions or trim links. Resistance or circuit response provides feedback for controlled processing. The operation connects wafer testing, parameter adjustment and verification through position-specific processing and measurement records.
- Applications: Trim thin-film resistor networks, accessible links and functional parameters in analog or sensor circuits that incorporate suitable trim structures. Define cut patterns, stop conditions and protected regions from the device design and measurement objective.
- Process inputs and outputs: Inputs include device wafers with documented resistor or trim-link layouts, probe pads, coordinate maps and target electrical parameters. Outputs are adjusted wafers, processing-location maps and measurements recorded before and after each defined adjustment.
- Configuration discussion: Coordinate laser wavelength, pulse delivery, focus, vision alignment and wafer motion with probe contact and the measurement circuit. Discuss feedback decisions, binning, reject handling, particle extraction and production-data interfaces.
- Quality and acceptance: Check target-parameter deviation, stability after trimming, cut geometry, residue, neighboring structures and passivation condition. Repeat measurements at agreed temperature, bias or environmental conditions, and verify the measurement system together with trim-stop rules.
- RFQ information: Supply the trimmable structure layout, material stack, electrical operating principle and target window. Include probe arrangements, allowed processing regions, protection requirements, representative samples, test programs and traceability rules.

FAQ
Questions before starting a project
Confirm the project boundary before sample testing and engineering configuration to reduce selection cycles.
View service & supportWhat information is needed before equipment selection?
Share part drawings or photos, material and thickness, process location, quality standard, target cycle time, and automation or interface requirements.
Is the configuration shown in the video final?
Videos illustrate operation and process direction. Laser source, optics, motion, tooling, vision and safety are configured for the actual part and project targets.
Do you support sample testing and process validation?
Yes. Submit materials, drawings and acceptance criteria; after the test scope is agreed, results can guide equipment selection.
How is the delivery scope defined?
The agreed project documents define the scope, which may include equipment, process validation, tooling, automation, training and service support.
