Semicera Semiconductor Wafer Supplier — End-to-End Wafer Solutions from Lab Customization to Mass Production

Semicera is a high-tech enterprise focused on the R&D, manufacturing, and sales of advanced semiconductor materials and core components, long serving the semiconductor, third-generation semiconductor, photovoltaic, and related high-end manufacturing industries.

1. Background and Positioning of the Wafer Division

Semicera’s Wafer Division was not established simply to sell standardized products — it grew out of customers’ real R&D needs.

In its early stages, many universities, research institutes, and semiconductor companies developing new materials and devices urgently needed wafers with special specifications, small batch sizes, and non-standard configurations. To meet these needs, Semicera started out by offering “laboratory customization services,” providing personalized wafer solutions based on customer requirements for material, size, crystal orientation, conductivity type, thickness, and other parameters.

As the customer base grew and R&D projects progressively moved into pilot and industrialization stages, the company continued investing in production equipment, testing instruments, and supply chain resources, gradually building a more complete wafer supply system.

Today, Semicera’s Wafer Division has grown from its original small-batch R&D support role into a comprehensive wafer supply platform capable of simultaneously supporting R&D, small-batch trial production, pilot production, and large-scale mass production — delivering more stable and efficient products and services to customers worldwide.

5. Standard Lead Times and Delivery Assurance

5.1 Standard Lead Times

Lead time mainly depends on product type, specifications, inventory status, and production schedule:

• Standard specification products: shorter lead time, fast shipment
• Custom products: scheduled for production according to process requirements, evaluated based on specific specifications
• Large-volume orders: coordinated according to the overall production schedule

Semicera's overall lead time is stable, ranging from 2 weeks to 60 days.

5.2 Factors That May Affect Lead Time

The following situations may extend the lead time:

• Statutory holidays
• Longer procurement cycles for special materials
• Last-minute changes to specifications or process requirements by the customer

For urgent projects, Semicera will coordinate its sales, technical, and production teams to meet customer delivery needs as much as possible, keeping customers updated on project progress to ensure normal production and shipment of wafers.

6. Quality Management System and Product Testing

Quality control runs through the entire process of Semicera's wafer product supply. Depending on product requirements, the following key metrics can be tested:

• Dimensional parameters: wafer diameter, thickness
• Geometric parameters: TTV (total thickness variation), Bow, Warp
• Surface quality: surface roughness (Ra), surface defects, appearance and particle contamination
• Electrical performance: resistivity
• Crystal properties: crystal orientation

Every batch of products is inspected according to the relevant specification requirements to ensure the products meet customer usage requirements.

7. Certifications, Test Reports, and Compliance Documents

Depending on the product type and customer requirements, Semicera can provide the following quality and testing documents:

• Product test reports
