A Brief Introduction To Wafer Cassettes & Mapping

Chances are, if you have reached this post, then you might be really curious to know about Wafer cassettes. Isn’t so? If yes, then you are definitely in the right place. In this write-up, you are going to get all the information concerning it. Let’s dive deeper into it!

Why Wafer Cassettes Are Used?

Well, wafer cassettes are used for the purpose of storing and transporting wafers during semi-conductor manufacturing working processes. Wafer Cassettes, also known as wafer carriers, among many people, are specially designed to carry many different wafers of the equivalent sizes. More so, these days, wafer cassettes are available in various ranges of materials in order to aid certain applications like thermal processing.

Basically, a vacuum wand is practiced to deposit and pick up wafers in cassettes. Later on, they are used to transfer the wafers between storage containers & processing chambers. Bespoke and customized cassettes are particularly used to design an interface with a certain storage container or a specific system.

Why Waffer Mapping Is Important To Predict Die-Level Failures?

In the semiconductor manufacturing process, wafer fabrication is followed up through chip assembly. In such a case, individual dies are frequently accumulated as a whole packaged chip. Numerous dies are tested in regards to electrical properties throughout the process. Those who fail to pass through the wafer test are then filtered out. Nevertheless, a portion of faulty dies pass this test & then make a packaged chip fail the major testing process. In such a case, the inaccuracy of the wafer tests directs to wastage of the cost and time. 

Dimensions Of Wafer Cassettes

Primarily, wafer cassettes can be characterized on the basis of the total number of imperative dimensions such as height, width, length. Rather than these, there are a few more specific dimension which is considered, such as:-

• Pocket Spacing – is basically the total distance between the center lines of every wafer pocket
• D1 Dimension – Dimension signifies the complete distance one end of the cassette to the centerline of the wafer pocket
• Pocket Flat – term stands for the width of every wafer pocket at its narrowest distance

However, the central idea behind the design of the wafer cassette mapping is to fit an extensive range of wafer sized perfectly, be it of 2.5 inches or somewhat 450 mm.

Looking For Wafer Cassettes Mapping Services?

In order to locate the provider rendering a wide variety of good quality wafer cassettes mapping services, you need to make sure to look out for some real pros. Remember that – enhanced cleaning standards and robotic handling processes in semiconductor wafer fabs demands a stable and non-contaminating wafer cassette mapping along with some unusual mechanical interface capability. 

You need to seek out for someone whose wafer cassettes are available for any type of application in varied sizes and materials to make the most out of the process.

Wafer cassette mapping and wafer front end are going to help you make the most out of your businesses, so what you been waiting for? Seek out for the right and reliable assistance and get the best out of it!
