ADVANCED WAFER BONDER

All about
W2W Hybrid Bonder

LTrin is a semiconductor equipment company developing productivity- and cost-competitive wafer hybrid bonders, built on three core technologies: Real-view Alignment, RF Induction Heating, and Cleanable AP Plasma.

LTrin's 3 Core Technologies

Clearly differentiated from global competitors.

CORE TECH 01

Real-view Alignment System

A glass-based monitoring specimen paired with high-resolution visible-light CMOS vision recognizes alignment keys directly, assisted by indirect recognition — without costly NIR/SWIR hardware.

Alignment MethodReal-view (standard vision)
Warpage ToleranceExcellent
Target PerformanceSub-100nm overlay
CORE TECH 02

RF Induction Heating System

Independently variable RF induction heating for the upper and lower stages delivers dramatically faster heating and cooling than resistive heating, maximizing throughput.

Heating Rate35–200℃/min
Cooling Rate35–85℃/min (N2 blow)
ThroughputUp to ~6x vs. competitors
CORE TECH 03

Cleanable AP Plasma

Combines surface activation and nano-spray cleaning in a single hybrid module — unlike competitors' two-module vacuum plasma systems — cutting footprint and shortening TACT.

Module Count1 (vs. 2 for competitors)
Throughput2x+ improvement
Bonding Strength> 2.0 J/m²
