The Importance of Wet Processing in the Manufacturing of Semiconductor Components

When it comes to semiconductor manufacturing, the fabrication process is a highly exacting and intricate one. Semiconductors require a contaminant-free space for the majority of production stages, exceptionally pure materials, and a well-engineered process. From start to finish, MultiSource Manufacturing, LLC provides comprehensive, high-quality fabrication of semiconductor components and assemblies using concurrent engineering processes, a class 1000 clean room, PFA fabrication, and much more.

Semiconductor components are highly present in today’s electronics-saturated world in the tools and devices we each use every day. From the cell phones so present in the routine of our lives to the complex computational and mechanical systems used at NASA and in the military, semiconductors have a vital role. The MultiSource network provides semiconductor components and assembly production including microchip reticle handling and purging, wafer and device handling system components, and wet processing for the primary production stages.

Wet processing is a critical stage in the manufacturing of all semiconductor components. It is during this process in which the format of the pure wafer is created. The wet processing steps are applied in the following way:

1. A resistant material is deposited into the surface of the semiconductor wafer following the engineered format desired of the final product. For the majority of semiconductors, that format is what visually creates a small roadmap of connected nodes.
2. The wafer is then submerged in or otherwise exposed to a liquid or vapor that will etch away the exposed wafer and leave behind the format of the deposited material.
3. Finally, the wafer is cleaned and inspected for quality before moving to the next stage of the manufacturing process.

While the wet processing stages of semiconductor component manufacturing is a small portion of fabrication as a whole, it’s a critical one. The wet etching and cleaning of a semiconductor wafer remains the most effective way of creating an exactly engineered format. This is also why it’s key that our team of highly-trained experts applies reverse engineering to this process as a whole. The format of a semiconductor is what makes it a functioning electronic component, and to create the correct format, our engineers must understand the desired result and work backwards to develop a solution.

With a well-versed team of engineers ready to come into the design process with the understanding of reversed development, well-made semiconductor wafers, a high-class clean room, and reliable fabrication technology, MultiSource is a trusted manufacturer of semiconductor components for OEMs and other customers.

Importance of Clean Room Standards for Manufacturing and Assembly of Semiconductor Components

Certain areas of the manufacturing operations we provide in the MultiSource Manufacturing network have very specific requirements for a controlled, contained environment during the production process. Specifically, our manufacturing of high-quality precision-based semiconductor components demands a clean room meeting exact ISO standards as well as our own self-imposed standards. The MultiSource network utilizes an ISO Class 3 clean room to eliminate the potential for contamination in every stage of the production process for semiconductor components and full assemblies.

With the protection our clean room provides, MultiSource is able to offer PFA fabrication and welding, in-house electric capabilities, and reverse engineering for even the most complex semiconductor projects.

Our Clean Room

All of our locations have access to our Burnsville facility’s clean room. This clean room meets ISO level 3 classification and Class 1 Federal Standard 209E for eliminating biocontamination and other forms of particulate contamination in the production process.

ISO 3/ Class 1 clean rooms limit the presence of contaminating particles down to:

● 1,000 per cubic meter of particles sized at 0.1 micrometers
● 237 per cubic meter of particles sized at 0.2 micrometers
● 102 per cubic meter of particles sized at 0.3 micrometers
● 35 per cubic meter of particles sized at 0.5 micrometers
● 8 per cubic meter of particles sized at 1.0 micrometers
● 0 per cubic meter of particles sized at 5.0 micrometer

This filtration of microorganisms and particles is critical for the successful production of semiconductor components and assemblies because of the nature of the materials utilized in their manufacturing. Semiconductor assemblies are derived from glassy, crystalline materials such as silicon that have an electrical conductivity decreasing in resistance as temperature increases. Because of this and other properties of semiconductor materials, they are utilized to build electrical assemblies with unique allowance for amplification and energy conversion. However, the process of building semiconductor designed for integrated circuits used in most electronic assemblies requires a highly clean environment, not only during the semiconductor seed material refinement to produce chips with complete clarity, but also during all following production and assembly of semiconductor and electronic components.

Even the smallest particle present in the manufacturing environment can, at the least, alter the quality of a semiconductor assembly and, at the most, completely damage the function of a component and the system as a whole.

With access to an in-house, high-level clean room, MultiSource engineers and technicians are able to consistently produce high-quality, precision-based semiconductor components and assemblies for OEMS and other customers.

How Kitting and Quality Electrical Assembly Services Benefit and Improve the Supply Chain

The development and implementation of lean manufacturing practices has been a key tool in improving the production processes for a wide range of industries. Not only does lean manufacturing promote waste reduction and environmental conscientiousness, but it also provides cost-effective, streamlined procedures for production and storage of goods. At MultiSource Manufacturing, LLC, our network of facilities applies lean manufacturing across the board for all our design, fabrication, assembly, packing, and delivery services, including kitting and electrical assembly services.

When it comes to precision machining and production of electronic components, a high-quality assembly process is key to creating a finished, reliable part. The MultiSource network provides comprehensive electrical assembly services, including electromechanical assemblies, electronics kitting, and we even have the capabilities to assemble and test completed devices. As part of our lean manufacturing standards, in-house kitting and electrical assemblies work to streamline our own production operations in the long-term as well as improving the efficiency of the supply chain for OEMs and our other customers.

Benefits of Kitting

Kitting works to group together separate items into a collection of cohesive units. This categorizing and blocking together of products into a kit unit is a key step in promoting lean manufacturing for electrical and electromechanical assemblies. Kitting provides a streamlined lean inventory and supply system for all MultiSource locations benefitting our customers with:

1. Improvements in the manufacturing process that ultimately decrease the amount of material processing and inventory handling during our own production and that of OEM customers.
2. Minimized warehousing and storage space demands by reducing the amount of space components take up and organizing components in an easily inventoried system.
3. More practical inventorying possibilities with a system that cohesively organizes components with improved capabilities in quality control.
4. Reduction of deliveries to customer locations, in turn lowering costs of shipping and saving storage space.
5. Minimized potential for component damages with reduced handling during shipment and inventorying.
6. Improved recording and processing of components and full assemblies overall.

Kitting is not only a useful way of categorizing and packing electronic components and assemblies into a cohesive unit that can be quickly and easily recorded and put into inventory, it’s also a true lean manufacturing practice that supports waste reduction and efficiency of production. For our high-quality precision machined electronic components and electromechanical assemblies, the MultiSource network relies on the benefits and capabilities kitting provides.
