Guide to Semiconductor Wafer Sort - AnySilicon
Wafer sort is a simple electrical test, that is performed on a silicon die while it’s in a wafer form. Wafer sort’s main purpose is to identify the non-functional dies and thereby avoiding assembly of those dies into packages.
Wafer testing - Wikipedia
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 (WFT), Electronic Die Sort (EDS) and Circuit Probe (CP) are probably the most common.

2018年4月3日 · Wafer sort is a crucial process in semiconductor wafer processing facilities. It is the first testing stop for completed wafers. The test results provide valuable feedback to multiple departments – production control, wafer fabrication, product …
Silicon Wafer Sorting Steps | UniversityWafer, Inc.
Silicon wafer sorting is the process of separating silicon wafers based on certain characteristics, such as diameter, thickness, resistivity, and surface finish.
Inkless Wafer Sort? Increased quality. No chance of inking incorrect dice or dripping ink on good dice. Reduce chance for wafer breakage and bump damage. Solder-bumped wafers can be re-flowed if necessary. Reduces count discrepancies. Improves data systems. Inkless Process Flow Example. Sort - Includes Multiple Sort Steps. Sort Data.
Electrical Die Sorting (EDS) | Samsung Semiconductor Global
2018年5月9日 · EDS is crucial to improving semiconductor yield rates. Yield is a percentage of prime good chips relative to the maximum chip count on a single wafer and is a direct indicator of semiconductor productivity. The EDS process is carried out by making the wafer come in contact with a probe card.
Inspecting IC Packages Using Die Sorters - Semiconductor …
2019年4月18日 · The sorter removes a die from a carrier using a mechanism, inspects the die, and determines whether the part is good or bad. The good dies are placed on various mediums, such as a carrier tape, waffle pack, jedec tray or film frame. Some sorters perform these tasks at 30,000 units per hour (UPH).
Crucial Silicon Wafer Testing: Unveiling Importance - Wafer World
2020年10月30日 · What is Wafer Sorting? Wafer sorting is just another way of saying wafer testing. It even has some other names as well, which include electronic die sorting and circuit probing. The goal of the test is simple – test a silicon die in wafer form to determine if it’s functional or not. If it’s a non-functional die, it will not be packaged.

Wafer test (or wafer probe or wafer sort) is a simple electrical test, that is perform on a silicon die while it’s in a wafer form. Wafer sort’s main purpose is to identify the non-functional dies and thereby avoiding assembly of those dies into packages.
RF wafer sort testing poses unique challenges with requirements for high signal integrity at high frequencies and bandwidth. This paper will discuss the measurement challenges and considerations for known good die testing of an RF SOC (system on chip) device. It will explore the challenges of setting up the multi-site wafer probe card and assembly.
