How Wafer Automation Helps Overcoming Productivity Challenges?

-
The complexity in the outsourced assembly and test (OSAT) the industry is blowing up owing to higher functionality demand, longer battery life, and thinner forms in handheld devices. OSAT factories are readily using complex packaging technologies for blurring the line between wafer packaging and wafer processing. Through Wafer Automation we are able to meet the challenges of various wafer-level architectures, like modern wafer fabrication.

The traditional packaging methods are no longer relevant; wafer automation has taken up the transition. The fabrication life cycles, characteristics, and activities have to be carefully learned before deploying in the OSAT environment. In this competitive wafer-level packaging (WLP) era, it is crucial to have higher-level manufacturing capabilities and engineering resources.

Comparison

Traditional OSAT production is relatively low-margin, and all the packaging services were in support of wafer requirements. The advanced packaging applications have relatively high margins and are growing much faster than the semiconductor industry. The OSAT companies are overcoming the competitive and technological challenges using Kensington wafer automation to reduce waste and errors, and get higher levels of output. The various automation strategies increase responsiveness and flexibility leading to more efficiency.

What Are The Automation Strategies For WLP?

WLP factories face challenges to deliver multiple products of various sizes at acceptable yield levels that manage varying levels of complexity and handles time commitments with the latest methodologies. They closely resemble wafer fabrication in structure, performance, and operations. The WLP factories need tools for photolithography, sputter, CMP, dielectric deposition, plating, cleaning, inspection, measurement, and testing. Each equipment to be used should be single-wafer, so that batch operations meet the production requirements. The production tools and automated material handling systems should be 300mm for operations. The monitoring and controlling of such complex production operations are beyond the OSAT companies did in the past.

What is FOUP? The FOUP is defined as Front Opening Universal Pod, which is the exclusive plastic enclosure equipped for handling the silicon wafers in a safe environment. The other name of FOUP is the Front Opening Unified Pod. The primary purpose of this device is to allocate the wafers in the machines to increase the processing performance. In the mid-1990s, 3000mm FOUP was developed as the wafer processing tool. Many companies design their FOUPs in different color combos, and their product sizes also vary according to the brand. In addition, IC processing equipment and the FOUP can provide the nitrogen ecosystem to boost the device productivity. Previously, the engineers may only develop the 300mm FOUP with the detachable cassette to place the wafer in the right position. But now, 400 mm wafer FOUP load ports are also easily accessible from the robotics laboratory. It may allow the swapping of doors from front to bottom so that robot mechanisms can access the wafer from the FOU

Silicon wafer is the main element in integrated circuits and is used in one-step production for moving firm substrates. Generally, the integrated circuit is a mixture of different electronic parts put together with silicon wafers placed on the main platform of semiconductor apparatuses. The wafer is finely cut for the semiconductor material so that it functions as the substrate over the wafer with microelectronic apparatuses incorporated. The silicon wafer stage used in cohesive circuits is used in contemporary society daily. Computers, smartphones, and other gadgets are completely reliant on these apparatuses. Semiconductors are examined many times before they are incorporated into the devices. Silicon wafers are used in sensors to gauge tire pressure and solar cells. The wafer’s primary function is soaking up the photons in sunlight to generate electricity. Researches on Silicon Wafers The silicon is used for producing superior silicon and other firm substrates for high-valu
