1. Purpose of the gate
The alpha tool is the first time the tool leaves the maker's hands. It will be installed in a real fab or a joint development site, run by the customer's engineers on the customer's wafers, and judged against the customer's own measurements. What happens there shapes the tool's design changes, the customer's view of the maker and very often the first production orders. Alpha shipment approval makes sure the evaluation is set up to produce useful learning, on terms that protect both sides.
The review checks the agreement as much as the tool. The joint development agreement must say who owns the data, the results and any improvements; what the customer may share; what happens to the tool at the end; and how confidential process information is protected. The evaluation plan must say what success looks like, in the customer's terms. The configuration must be recorded so that every result can be traced to the hardware and software that produced it. And export screening must be complete for this specific shipment.
The gate criteria are an alpha evaluation plan agreed with the customer, with success criteria; a signed joint development agreement covering data, results and intellectual property; a recorded alpha tool configuration; export screening complete for this shipment; and the installation procedure and site preparation issued to the customer. The key decision taken and frozen at this gate is alpha site and lead customer partnership.
