How to Record Raw Silicon Wafer Purchases
Accounting for the acquisition of blank silicon wafers (e.g., 300mm) before they enter the photolithography process.
How to Record Clean Room WIP Absorption (Power, Gases, and Labor)
Allocating the massive overhead costs of a 'Class 1' Clean Room environment to the chips currently in production.
How to Record Wafer Yield Variance (The 'Good Die' Adjustment)
Adjusting the value of inventory when a wafer produces fewer working chips (Die) than the theoretical maximum.
How to Record Die-Bank Inventory (Unpackaged Chips)
Accounting for 'Finished Wafers' that have been cut into individual dies but not yet 'Packaged and Tested' (OSAT).
How to Record Silicon and Precious Metal Scrap Recovery
Accounting for the value recovered from defective wafers or manufacturing byproduct (e.g., gold/copper/silicon recycling).
How to Record and Capitalize Photomask (Mask Set) Costs
Accounting for the high-cost master 'stencils' used in the photolithography process to project circuit patterns onto wafers.
How to Record NRE (Non-Recurring Engineering) Revenue
Accounting for fees charged to a customer for the specialized design and development work required before mass production begins.
How to Record IP Core Licensing (Upfront Technology Access Fees)
Accounting for the purchase of 'blueprints' or functional blocks (e.g., an ARM CPU core) to be integrated into a chip design.
How to Record Sales-Based IP Royalty Expenses
Accounting for the recurring 'per-chip' fees owed to IP providers for every unit sold to an end customer.
How to Record EDA (Electronic Design Automation) Software Licenses
Accounting for the multi-year subscription costs for specialized chip-design software (e.g., Cadence, Synopsys).
How to Record Clean Room Infrastructure Construction
Accounting for the specialized build-out of a 'Class 1' environment, including raised flooring, HEPA filtration, and vibration-isolated foundations.
How to Record Semiconductor Tool Hook-up and Qualification Costs
Capitalizing the labor and materials required to connect a multi-million dollar lithography tool to electricity, gases, and cooling.
How to Record Specialized Gas and Chemical Delivery Systems
Accounting for high-purity stainless steel piping and chemical distribution systems used to transport toxic materials to the factory floor.
How to Record Accelerated Depreciation for Process Node Transitions
Adjusting the useful life of existing Fab equipment when a decision is made to transition to a smaller nanometer node (e.g., 7nm to 5nm).
How to Record High-Value Capital Spares (Strategic Inventory)
Accounting for critical, high-cost components (e.g., specialized lenses or vacuum pumps) held for the immediate repair of Fab tools.
How to Record Die-Bank NRV Write-downs (Unpackaged Chip Obsolescence)
Accounting for a reduction in the value of unfinished dies sitting in storage when the market price for the final product falls below production cost.
How to Record Distributor Price Protection (Ship-from-Stock-and-Debit)
Accounting for credits issued to distributors to compensate them for inventory on their shelves when the manufacturer lowers the market price.
How to Accrue OSAT (Outsourced Semiconductor Assembly and Test) Costs
Recording the liability for packaging and testing services performed by third-party vendors (e.g., ASE, Amkor) at month-end.
How to Record a Field Failure and RMA Reserve
Estimating a liability for chips that will fail after being integrated into customer products (e.g., phones or cars).
How to Record R&D Tax Credits for 'First Silicon' Development
Recognizing the tax benefit for the massive engineering labor costs involved in bringing a new chip design to 'First Silicon' (functional prototype).
How to Record Chip Binning and Grade Reclassification
Accounting for the reclassification of inventory when a single manufacturing run produces chips of varying performance 'bins' (e.g., Gold, Silver, and Bronze grades).
How to Record Patent Portfolio Licensing Revenue
Accounting for revenue earned by a chip-maker (e.g., Qualcomm or Rambus) for granting other companies the right to use their patented technology.
How to Record Evaluation Board (EVB) Sales and Costs
Accounting for the sale of hardware development kits used to win 'Design-ins' with customers, often sold at or below manufacturing cost.
How to Record a Strategic Inventory Buy-back (Channel Cleanup)
Accounting for the repurchase of chips from a distributor to prevent 'Gray Market' sales or to make room for a newer version.
How to Record an IP Indemnification Legal Reserve
Recognizing a loss contingency when a customer is sued for patent infringement and the chip-maker is contractually required to cover the legal costs.
