Reliability Assurance

O2Micro is committed to ship highly reliable products. Products use proven and reliable standard semiconductor manufacturing processes. Reliability verification is performed according to industry-wide standards to meet customer expectations for product reliability. Production reliability monitoring are performed to assure device performance and to accumulate statistical data.

Wafer FAB Process Qualification


O2Micro is a fabless IC design company. All products adopt the mature processes of the wafer foundries, and these processes must pass the wafer-level reliability qualification. These evaluations results are incorporated into product design rules to avoid product stage failures and ensure long-term reliability.

TDDB: Time Dependent Dielectric Breakdown

QBD: Charge to Breakdown

VBD: Voltage to Breakdown

HCI: Hot Carrier Injection

NBTI: Negative Bias Temperature Instability

Vt Stability: Threshold Voltage Stability

EM: Electro-Migration

SM: Stress-Migration

etc…



New Product Qualification

Product reliability can be divided into two categories, one is Device Reliability which related to chips, and the other one is Package Reliability which related to assembly.

Device Reliability Tests

HTOL, ESD, and LU are evaluated in all O2Micro products.

HTOL: High Temperature Operating Life Test

Performed with both Voltage and Temperature acceleration to accelerate IC aging to evaluate product lifetime.

ELFR: Early Life Failure Rate

Using high temperature and voltage to accelerate the failure and to screen out the early failure devices.

ESD: Electrostatic Discharge

ESD while only a slight annoyance to people, provides a challenge to electronics where the fast increase in voltage and current has the potential to cause severe damage. ESD tests include Human Body Model (HBM) and Charged Device Model (CDM) performed to guarantee that the IC achieve immunity to these discharges.

LU: Latch-Up

Fabrication of CMOS integrated circuits with bulk silicon processing creates a parasitic SCR structure. When triggered and turned on by extrinsic surge, etc., cause continuous large current flow. Latch-up test is for evaluation of resistance (immunity) to the phenomena where continuously flowing large currents cause latch-up.

Package Reliability Tests

Package reliability test is used to verify the protection capability of a specific package and the manufacturability of SMT (Surface Mount Technology). Under different temperature, humidity test conditions, packaging materials show different thermal stress, moisture resistance and chemical properties.

PC: Preconditioning

PP: Pressure Pot

TCT: Temperature Cycling

PTC: Power Temperature Cycling

u-HAST / HAST: Un-Bias / Bias Highly Accelerated Stress Test

HTS: High Temperature Storage

LI: Lead Integrity

PD: Physical Dimensions

SD: Solderability

HS: Hand Solder

WBS: Wire Bond Shear

WBP: Wire Bond Pull

etc…

These package reliability tests are performed for the qualification of new assembly sites, new package processes and package BOM (Bill of Material) changes and will take a long time. O2Micro has a large database, which can be used for rapid risk assessment and reduced verification costs. In addition to the reliability test items mentioned above, we can also evaluate whether other items can be performed according to the needs of customers.

Ongoing Reliability Test (ORT)

All O2Micro products are subject to reliability qualification plans based on their application field and package type, considering the AEC-Q100 and JEDEC standards. These plans include completing all qualification items to meet O2Micro 's reliability targets before proceeding to mass production. However, the work on reliability does not end once mass production begins. ORT is conducted to ensure that the product's reliability is maintained throughout the production phase. For general consumer products, O2Micro establishes an ORT plan based on wafer fabrication processes and package types, typically conducted on a quarterly basis. In the case of automotive products, which require higher reliability standards, ORT is mandatory for the specific product. The test items must include the previously mentioned relatively short-duration tests such as HTOL and PC.

Foundry ORT (Ongoing Reliability Test):

V: Performed and passed.

Assembly ORT (Ongoing Reliability Test):

V: Performed and passed.

Failure Analysis

Failure analysis is a systemic and structured workflow for tracing back the failure results of a device, part, or component.

It plays a key role in PDCA improvement quality system. The improvement and preventive actions are based on failure analysis results. Through data collection and analysis, problem definition, hypothesis and validation, proper analysis procedures, experience, historical database review and most importantly, logical judgment are key to accurate failure analysis.

To ensure product quality with find out why a device, part or component fails are called failure analysis. It is a systematic and adjustable process that traces the causes of failure. Based on the results of failure analysis to make improvements or prevent future failures. To do failure analysis accurately which needs to collect information, handle samples properly, follow analysis procedures, use experience and logic, and review historical data.

The failure samples come from different sources, such as customer returned or feedback, reliability tests, engineering experiments and low yield parts.

 

Generic Failure Analysis Procedure:

Failure analysis does not stop at finding the source or identifying the cause of failure.

All products manufacturing steps quality control skills are reviewed for continuous improvement purpose.

A database stores the analysis results and FA procedure incorporates the improvement or prevention

activities.
