Micrologic 1960 Classify Ship First Commercial Integrated Circuits

# Classify and Ship: The First Commercial Monolithic Integrated Circuits

## 1. Why the Unit of Value Just Changed From a Device to a Function

This closing step classifies, packages, and ships circuits that passed Step 6's functional test, Step 7's yield gauntlet, and Step 9's military qualification — and the economics this series finally delivers are not measured in cost per transistor, the metric 1957's Step 15 introduced, but in cost per logic function, a genuinely new unit of value this project has never needed until a single chip could replace several separately packaged devices wired together on a circuit board. A customer buying a 1958 mesa transistor bought one component and still had to buy, mount, and wire every other component their circuit needed around it. A customer buying one of these flat-packs buys the transistors, the resistors, the isolation, and the interconnect all at once, pre-wired into a working function — and the number that matters to them is not what any one component inside costs, but what the finished function costs compared to building it from separate parts:

$$C_{\text{func}} = \frac{C_{\text{chip}}}{N_{\text{functions}}}, \qquad C_{\text{func, IC}} < C_{\text{func, discrete}} \iff Y_{\text{circuit}} \cdot \left(1 + \frac{C_{\text{assembly}}}{N_{\text{components}} \cdot C_{\text{part}}}\right) > 1$$

where $C_{\text{chip}}$ is this circuit's selling price, $N_{\text{functions}}$ the number of logic functions it performs, and the right-hand inequality states the condition under which this chip, despite Step 7's lower yield than any single component would have, still beats a discrete assembly on cost — because the hand-wiring and inspection labor a discrete circuit requires, $C_{\text{assembly}}$, is a cost this chip's single packaging and test sequence has already absorbed. For Minuteman and Apollo, where that assembly labor was itself a source of the reliability failures this series' own Steps 7 through 9 were built to catch, the inequality holds by a wide margin.

A Lower Yield Still Wins, Once Assembly Labor Counts cost per function, integrated versus discrete, same circuit COST PER FUNCTION, TWO WAYS TO BUILD THE SAME GATE DISCRETE ASSEMBLY parts, cheap individually hand assembly and wiring, the dominant cost THIS CHIP one part, pre-wired, tested as a function yield cost, step 7's penalty, already paid for Cfunc, IC < Cfunc, discrete once assembly labor, not parts cost, dominates the comparison the yield penalty this series paid in step 7 is smaller than the labor cost it replaced

## 2. Real Diagram: Ten Series, One Arc, From a Single Point Contact to a Shipped Function

This series' closing diagram extends the lineage this project has carried since its first entry — the 1947 point-contact transistor — through every intervening series, to the moment a customer can order a function rather than a component.

From One Point Contact to One Shipped Function 1947 through 1960, the unit of commerce itself has changed 1947 one device, one whisker 1954–58 one device, batch produced 1959 one reliable device, oxide covered 1960 one function, several devices, shipped as one part the unit this industry sells has moved, in thirteen years, from a device to a function

## 3. Why This Series Closes a Chapter That Started With a Single Whisker Touching Germanium

Every series this project has documented, from the 1947 point-contact transistor through the 1959 planar process, improved, scaled, or protected a single device. This series is the first to change what the customer is actually buying: not a transistor, however reliable, but a function, pre-assembled and pre-tested, that a 1947 engineer would have needed several separate devices and a soldering iron to build. The reliability this project fought for across nine prior series — the diffusion control of 1954, the batch economics of 1957, the exposed-junction fix of 1959 — are not superseded by this series; they are the precondition for it, because a function built from unreliable components would never have cleared Step 7's multiplied yield penalty at all. Apollo's guidance computer and Minuteman's flight control, the two programs this series' qualification named, would run on exactly this kind of part for the rest of their service lives.

Step 10 does not finish a device; it finishes a function, and in doing so closes the arc this project has been tracing since a single point of contact first proved that a crystal of germanium could do something a vacuum tube could not.
