Wafer testing - Wikipedia

WebOct 31, 2024 · CP：直接对晶圆进行测试，英文全称Circuit Probing、Chip Probing，也称为晶圆测试，测试对象是针对整片wafer中的每一个Die，目的是确保整片wafer中的每一个Die都能基本满足器件的特征或者设计规格书，通常包括电压、电流、时序和功能的验证。 Wafer testing is a step performed during semiconductor device fabrication after BEOL process is finished. During this step, performed before a wafer is sent to die preparation, all individual integrated circuits that are present on the wafer are tested for functional defects by applying special test patterns to them. The wafer testing is performed by a piece of test equipment called a wafer prober. The process of wafer testing can be referred to in several ways: Wafer Final Test … WebInvestor Relations. ESG.
