Semiconductor devices integrated circuits part 20.

General specification for film integrated circuits and hybrid film integrated circuits

Part One. Internal Visual Inspection Requirements

1 Scope

1.1 Purpose

The purpose of this document is to examine the internal materials,

Structure and manufacturing process.

This inspection is usually performed before capping or packaging to find and eliminate devices with internal defects. This defect will cause the device

Ineffective in normal applications. Other acceptance criteria should be agreed with the purchaser or supplier.

1.2 Check sequence

When conducting internal visual inspection, it is not required to follow the order used in this test and can be adjusted according to the requirements of the contractor. possible due to subsequent assembly

Wherever you can see it, inspect it before assembling it.

1.3 Check the equipment

The equipment used in this test includes optical instruments with specified magnification and some auxiliary visual inspection standards or instruments (such as rulers, charts

paper, photographs, etc.), these devices are required for effective inspection and enable the operator to make an objective judgment on the acceptability of the device being inspected.

Provide appropriate fixtures during the inspection process to facilitate operation, improve inspection efficiency and avoid damage to the device.

1.4 Check the environment

Under consideration.

1.5 magnification

"High magnification" (100x to.200x) inspection usually refers to the device under lighting conditions, with the microscope vertically aligned with the surface to be observed.

Inspections carried out.

"Low magnification" (10x to 100x) inspection usually refers to using a single tube, binoculars or

Examination using a stereomicroscope.

1.6 Description

The "presentation" mentioned here means that the visual image or visual appearance of the device being inspected indicates that the condition exists and does not require any verification.

How to confirm again.

1.7 Alternative inspection methods

The visual inspection methods given below are not the only methods that can be used during visual inspection.

However, manufacturers should meet the requirements of the National Authority (NAI) that any alternative methods will be subject to the same quality assurance, otherwise

The benchmark method should be used for testing.
