For now, there has two ways to inspect wafer-loading when the operators mske visual inspection.One way is using vacuum pen to access wafer then operators make visual inspection.The other way is using wafer loader equipment.Wafer loader equipment will automatically take wafer out from wafer cassette then put onto another inspection device for easy review.Using vacuum pen is very easy to cause wafer surface defects due to operator's mistakes.And using wafer loader equipment is critical inconvenient because wafer must be sent to another inspection device as reviewing reverse-side.
The advantages of the automatic wafer visual examination equipment could help operator to inspect wafer by multiple angles, meanwhile also could access wafer safely with the features of easy using, low equipment cost and high production capability.
