Why India's Semiconductor Industry Is Creating New Business Opportunities

Semiconductor-based technologies such as smartphones, electric cars, and medical devices have become indispensable for people all over the world. With the growing interest in these technologies, all companies along the semiconductor production chain have started attracting more interest, especially companies dealing with testing, packaging, equipment provision, and engineering support.

The effort of India to set up its domestic semiconductor manufacturing industry is providing an additional boost to this sector. Various government projects, such as India Semiconductor Mission and recently announced Semicon 2.0 scheme, will help enhance the capability of the country in terms of semiconductor manufacturing, packaging, equipment, materials, and research. This will create openings for specialised companies that would be servicing the manufacturers but not actually producing semiconductors.

Testing and packaging of the product are crucial stages since the chip produced needs to satisfy certain performance criteria prior to being supplied to an electronics company. The semiconductor plant requires appropriate equipment, maintenance services, process support, and qualified technicians.

But the opportunity does not necessarily have to be about creating a massive industrial plant. Entrepreneurs who have the necessary skills and industry knowledge can venture into more focused services. What needs to be done is to find out the need of a particular client and then create a business that can satisfy this need.

Understanding Chip Testing, Packaging, ATMP and OSAT

Before considering the choice of the business model, it is useful to be aware of the post-production processes related to semiconductor chips. The key stages in this case are testing and packaging, both of which require special approaches and equipment.

Testing of semiconductors is carried out to ensure that the chip conforms to its electrical, operational and performance specifications. This process depends on the type of the semiconductor and could be conducted at various stages of manufacturing. Some of the tests carried out may be to determine electrical characteristics, locate defects and evaluate reliability.

Packaging of semiconductors includes putting the fragile semiconductor into a package and creating the electrical contacts required for incorporating it into an electronic device. Various technologies can be used in semiconductor packaging based on the design, end use and performance characteristics of the device.

There are two industry terms used in this context:

• ATMP (Assembly, Testing, Marking and Packaging): Deals with the manufacturing processes required in assembling and packaging semiconductors.
• OSAT (Outsourced Semiconductor Assembly and Test): Used to denote companies offering assembly and testing services for semiconductor manufacturers and other clients.

Even though both these models have some similarities, they represent different concepts in the industry. While ATMP is an acronym for manufacturing processes, OSAT stands for a service model in the industry. However, expertise is required in both cases, but the nature of equipment, scale of production and capital differs depending on the services offered.

Five Business Opportunities in the Semiconductor Supply Chain

India’s expanding semiconductor industry presents various opportunities that fit different companies based on their technical capabilities and investment potential. Some of the options may involve sophisticated production setups, while others would involve simply providing equipment or services to current plants.

These companies need testing equipment, probes, sockets, handlers, fixtures, replacement parts, and other specialized items as well. The entrepreneurs can try their hands on equipment sales, components supply, or sourcing through association with some well-known manufacturers. Under this method, there is no necessity to run a whole semiconductor manufacturing plant, but still certain conditions are needed.

5. Equipment Maintenance and Technical Support

The testing and packaging units for semiconductors make use of special machines, which need to be installed, maintained, and provided with troubleshooting services. Such businesses as have engineering knowledge in this field can offer services like machine servicing, supply of spare parts, and maintenance services. Some of the services need the authorization from the manufacturer and some special skills. Entrepreneurs need to know the kind of equipment they can work with.

The right entry point depends on the intended customer base and available capabilities. Equipment supply and selected technical services offer alternatives to building a manufacturing facility, while testing, advanced packaging and ATMP/OSAT operations require progressively specialised infrastructure and process expertise.

Investment Requirements and Major Cost Components

The investment required to enter this industry varies significantly with the chosen business model, equipment specifications, production capacity and technical requirements. A company supplying testing components will have a very different cost structure from one establishing a semiconductor packaging facility.

The following are preliminary investment estimates for different business models. Actual costs will vary with technology, equipment capacity, facility requirements, imported machinery and project scale.

For businesses planning to enter this sector, the major expenses generally include:

• Equipment and machinery: Testing instruments, automated testers, handlers, probe stations and packaging machinery. Depending on the operation, this could account for a substantial share of the initial investment.
