01Laser kerf and processing sequence locatedUnconfirmed
Have material changes been located at the laser kerf or neighboring material, with the laser/blade/plasma sequence identified?
Separate prior grinding/debonding cracks, plasma-sidewall chemistry and protective-layer residue. The words “crack” or “debris” do not identify a thermal root cause.
Update engineering conditions →02Kerf material changes and known-good samples are comparableUnconfirmed
Are paired observations of kerf melting, cracks and material morphology available at the same location before/after processing and on known-good samples?
Endpoint photos or strength values alone cannot establish thermal effects. Record sampling, visible regions, surface/cross-section methods and sensitivity.
Update engineering conditions →03Earliest damage and actual processing history are traceableUnconfirmed
Are staged inspections at the same location available for grinding/debonding, protection, grooving, removal and subsequent dicing?
Recording only final singulation cannot identify the earliest new damage. Subsequent protective-coating, blade and plasma treatments may change the evidence.
Update engineering conditions →04Actual pulses/scans and delivery are traceableUnconfirmed
Can the actual material stack, wavelength/pulses, energy delivery, focus, scanning/pass count and thermal-loading boundary conditions be traced?
The USP name or an equipment recipe does not establish delivery to this stack. Method data require actual settings/checks; do not borrow speeds or recipes from the report.
Update engineering conditions →05This stack and evidence-collection/test methods are comparableUnconfirmed
Are the actual material stack/thickness, support, tensile test face and known-good comparisons available?
Three-point bending of bare silicon without Low-K, with the backside in tension, cannot represent arbitrary devices. Morphological, mechanical and functional inspections each require their own assessment criteria.

- DISCO · DISCO ultrashort-pulse processing and strength-test scope ↗
View source notes and limits
The manufacturer’s 2023 technical test compares blade dicing after laser grooving and records groove-bottom melting and three-point bend strength. Specimens were bare silicon without Low-K, tested with the backside in tension.
Relative-strength and thermal-effect statements apply only to that test. They do not provide general HAZ dimensions, pulse/scan recipes, damage-free device qualification or validation of Low-K/multimaterial stacks. Mechanical strength alone cannot establish sidewall chemistry.
- DISCO · DISCO plasma dicing, street pretreatment and supply capabilities ↗
View source notes and limits
Official pages list vacuum Bosch dicing, mask/street-film/metal pretreatment and a backgrind/mount/laser-groove/plasma sequence, and describe plasma equipment and test-dicing support.
The supplier’s description of no mechanical machining debris does not establish absence of passivation polymer, chemical damage or mask residue. These materials, process configurations, service availability and participation remain unconfirmed.
- ASMPT SEMI Solutions · ALSI LASER1206 multi-beam laser dicing and grooving ↗
View source notes and limits
The named product page and September 2025 launch identify LASER1206 capabilities. Low-heat-impact claims do not prove zero damage on your samples.
Scope and limitations Do not combine dicing/grooving ranges. Planar positioning accuracy is not kerf accuracy, and other materials/models do not establish your stack’s damage or yield. What to prepare BLNKK suggests preparing stacks, thickness, streets/metal layout, support and coatings; correlate kerf, heat-affected zones, sidewalls, strength and electrical results on matched samples. Confirm with the supplier Confirm wavelength, pulses, beams, scans, thickness applicability and coating/cleaning. Obtain stack-specific trial cuts and agree on dimensional/damage measurement and acceptance.
- TOWA Corporation · LSG1040 laser package singulation ↗
View source notes and limits
The named page lists twin lasers/tables; the May 2025 release describes dry processing and flexible package shapes.
Scope and limitations Non-contact, water-free processing is not heat-free or compatible with arbitrary wafers. Read sources do not guarantee damage, thickness or strength for a target stack. What to prepare BLNKK suggests documenting stack/streets, laser/scanning settings and existing defects, with sidewall, heat-affected-zone, contamination and strength comparisons. Confirm with the supplier Confirm materials/thickness, laser configuration, paths and parameter window, together with debris handling, inspection and sample acceptance criteria.
- DISCO · DFL7341 internal-modification laser singulation ↗
View source notes and limits
The product page documents machine scope; the separate library explains modification and expansion.
Scope and limitations Library separation equipment is not necessarily installed on the saw. Dry processing does not prove damage-free stacks. What to prepare BLNKK suggests preparing transmission/absorption, stacks, thickness, streets and focus conditions, plus sidewall, strength and electrical comparisons. Confirm with the supplier Confirm laser configuration, modification depth, height controls, expansion equipment/conditions and target-wafer damage validation.
- Tokyo Ohka Kogyo Co., Ltd. · TOK TLDP-300 laser-process protective coating ↗
View source notes and limits
The named section identifies the formulation and application, with processing/cleaning images rather than project-specific damage or residue specifications.
Scope and limitations Protection does not guarantee zero particles, residue or heat-affected zones, or repair existing damage. Water solubility does not establish device wash compatibility. What to prepare BLNKK suggests gathering stack/surface materials, wavelength and pulse/energy, coating/thermal histories, cleaning constraints and defect images. Confirm with the supplier Confirm thickness, coating/drying/removal, laser/material compatibility and comparison methods for residue, particles and cross-sectional damage.
- LPKF Laser & Electronics SE · NEXAR Ablate glass-core street RDL removal ↗
View source notes and limits
The product page describes removal applications and M/S/P configurations; the platform page distinguishes ablation from via formation and bonding.
Scope and limitations Removal is not complete singulation or a guarantee against damage or residue. Handling and monitoring depend on configuration. What to prepare BLNKK suggests preparing layer materials and thicknesses, glass specifications, street drawings and the downstream cutting flow. Confirm with the supplier Confirm the model, monitoring options and removal recipe, plus inspection methods for residue, cross-sectional cracking and glass strength.
- ISRA VISION · DicingScan dicing-street optical inspection ↗
View source notes and limits
Official information describes front/rear inspection and street chipping detection.
Scope and limitations Surface images do not establish thermal-affected depth or buried damage. Normal appearance does not prove damage-free laser cutting. What to prepare BLNKK suggests preparing wafer/tape details, street dimensions, cutting conditions and defect maps, alongside reference samples. Confirm with the supplier Confirm illumination, detectable defects and front/rear configuration, and when cross-sections or other analysis are needed for buried damage.
