ST typically engages with customers through three different business models. One option is for ST to obtain specifications from the customer, provide design simulations and then samples. By using this option, ST takes over 100% of the design responsibility. Another option is for ST to deliver a CAD-based design suite to the customer and let the customer design the device needed. Based on Gerber files, ST will then ship the wafers to the customer. This option requires an additional NDA to be signed. Please feel free to contact customer support to learn more. The third option allows for a collaborative effort between the customer and ST. The second and third options are used when there is need for ST to function as a foundry partner.
