Quality Management System

Quality Policy

To satisfy our customers’ targets through optimization of process capability and continuous improvement throughout our organization.

OSE is a customer-oriented company developing multi management systems. Our quality and service are admirable for customers. Many significant customers become good partners with OSE in business.
OSE is a historic and international semiconductor assembling and testing company with leading assembling technology . Our commitment in product delivery is capable to meet customers’ requirements and strict implementation in quality control. For customers, we firmly persist in performing satisfactory continual improvement.

Quality Management System

OSE established a quality management system according IATF 16949 and ISO 9001 including six customer-oriented processes: customer communication process, product and process development process, purchasing and material management process, ordering process, manufacturing process and after sales process. We define key performance indicators(KPI) for each process to continually assess and monitor it effectiveness and efficiency. Also, OSE is assessed and verified as meeting of requirements of IATF 16949, ISO 9001, ISO 14001, OHSAS 18001 and ANSI/ESD S20.20.

Total Quality Management

OSE develops total quality management aiming at design QA, supplier QA, manufacturing QA and sales and services QA, also at cost, delivery, human resource and environment and safety.
OSE continually converts customers’ requirements and internal needs into customer expectation and standardization by external audit and internal diagnoses and supporting by education and on-the job training.

Non-destructive Analysis

Curve Tracer



30W, 2000V/0.1A,20V/1.5A


Curve tracer is a electronic test equipment used to analyze the characteristics of semiconductor devices.


SEC X-eye SF-160


Real time observation


X-ray is used for illustrate the internal structure through x-ray.

SAM (Scanning Acoustic Microscope)

Sonoscan P300


Transducer frequency:


SAM is used to examine, measure and photograph the IC structure with supersonic waves.

SEM (Scanning Electron Microscope) & EDS (Energy Dispersive Spectrograph)

Hitachi SU8010(SEM)


Magnification: 10X~100000X


SEM is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons.
EDS is an analytical technique used for the elemental analysis or chemical characterization of a sample.

Digital Microscope



Real Zoom Lens: 20~200X/ 100X~1000X


Digital microscope is an optical microscope that uses optics and a digital camera to magnify the sample with 3D contrast (DOF) to output to the monitor .

High/Low Power Optical Microscope

Nikon LV150


Eyepiece: 10X
Objective Lens:


High/Low Power Optical Microscope is a type of microscope to use visible light and a system of lenses to magnify the preliminary inspection of sample surface structure.

Destructive Analysis

Grinding/Polishing Machine

Struers Tegramin-20


Variable platen speed:
40~600 rpm


The Grinding and Polishing machine is the tool used to grind/polish the sample near-by the suspected point for further investigations.

Precision Sectioning Saw

Allied 20-1000


Various Blade Type, Max Speed:4000 rpm


Precision Sectioning Saw is the machine tools used for cutting the sample before grinding.

Laser Decap

Con Semi FAT cat II


I.R. Laser: 20 watt


Laser Decap is the process of removing the protective cover of a microchip so that the contained die is revealed for visual inspection of the micro circuitry imprinted on the die.

Ion Milling

Hitachi IM4000


A/ V : 0 to 6 kV
Milling rate (max.) : (Materials Si)
For X-section milling: 300μm/hour
For Flat milling: 2~20μm/hour


Ion milling machine thins the sample until it is transparent to electrons by firing ions at the surface from an angle and sputtering material from the surface.

Probe Station

MM 6000


4 Manipulator


Probe station is used to physically acquire signals from the internal nodes of a semiconductor device.
