Meaning
A legal term within a semiconductor manufacturing agreement sets financial penalties for batches that do not reach a minimum functional output percentage. Integrating a yield debit clause protects the buyer from paying full price for low-quality silicon. If the foundry delivers fewer working chips than promised, the unit price drops automatically to compensate for the lost value.
This mechanism shifts some of the production risk onto the facility managers.
Output Shortfall
Calculated totals of usable die are compared against the average industry benchmark for that specific process node. Applying the yield debit clause requires a count of functional chips after the final electrical test. Foundries monitor their equipment daily to avoid triggering these payout requirements.
Financial Adjustment
Invoices are recalculated to subtract the penalty fees associated with poor manufacturing quality. The language of the yield debit clause specifies how much money is removed for every percentage point missed. These reductions are subtracted directly from the balance of the master supply contract.
Breach Boundary
Persistent failures to meet minimum standards give the buyer the right to move production to a different vendor. Under the yield debit clause, three consecutive low batches initiate a mandatory process review meeting. If no fix is implemented, the contract is considered broken and full legal remedies apply.
