How long does epitaxial growth take?
The development process for all products of IVWorks begins after a sufficient preliminary agreement is made in accordance with thin-film device characteristics requested by customers. Each product is customized to meet customer requirements. Therefore, the process periods may vary depending on the customer requirements.
How do customers purchase products?
Anyone who wishes to purchase our products or receive estimates can fill out the form below, and our engineers will contact you within 1-3 days.
Where can I check product prices?
All products are customized in accordance with customer requirements, so different products have different prices. The final price is determined based on our internal price guideline and engineers’ examinations.
How can I know if the wafers I received meet the requirements I submitted?
The crystalline property, surface resistance, electrical characteristics, etc. of grown GaN epiwafers are meticulously checked using OM, SEM, AFM, etc. before delivering epiwafers to the customers. Each customer is provided with the data collected in the process.
