Silicon Dioxide Flourished
Test Grade Wafers

Diameter: 100 MiliMeters
Orientation: Flat <100> Planar
Positive Charge-Type Boron Dopant
Resistance: 0-100 Ohmic CentiMeters
Thickness: 525 Microns
Polish: Single Sided

Grown Oxide Layer: 540 NanoMeters

Subsequent Etch -> New Layer: 520 NanoMeters

Specialized Start

The process initializes from a special order of 25 single crystal silicon wafers. Each wafer is delicately placed in a high temperature rated quartz holder with equal spacing. The entire cascet is then transfered to a furnace, where the wafers are subjected to a humid 1,100 ° Celsius atmosphere for exactly 48 minutes 56 seconds. This exposure grows an oxide layer of a certain thickness, 540 nanometers. Some wafers are destroyed from the extreme furnace conditions. The resulting color from the genrated thin film is an aqua blue terrestrial green blend.

Rainbow Film Navigation

Shifting the ambient observed color spectrum requires alterations to the silicon dioxide layer. Immersing the wafer in a 40% hydrogen fluoride solution etches 0.6 nanometers per second. Floating 33.4 seconds in the treatment disintegrates 20 nanometers of the oxide layer. The background color of the wafer now ranges from nova green, to deep sky blue, to galaxy stellar violet. Changing the view angle transitions from one shade to another. After a cycle of water spin, rinse, drying the wafers are primed for further detail.

Triple Element Synchronous Discharge

Metallic Vaporization

Escaping non conductance requires additional layer construction. The wafers are suspended inversly to the cieling of chamber depressurized to 10-6 Pascals or 10-9 Torr. Ultra high purity nitrogen or argon then floods the environment. Powerful electronic magnets ionize the atmosphere in a controlled plasma ring. The neon like pulse strikes metallic targets, fragmenting them into airborne particles.

Combining multiple metallic targets in the same active chamber can produce highly controlled alloys. Plasma ring exposure can be timed to generate either cascades or steady mixtures of metals. Unique compositions exhibit various electrical or chemical properties. Succesful depositional finishes are often mirror like, highlighting the precise nature of micro fabrication. This new conductive substrate provides a pathway for the free movement of charge carriers.

Metal misted wafers are then transported to a centered disc. Small drops of positive photo resist are applied to the surface. The disc begins to spin the wafer up to 6,000 revolutions per minute to evenly distribute the light sensitive liquid. Soft then hard baking the wafer laminates the photo resist. Moving to a lithography machine, an aligned tailored polymer mask imprints its design by allowing only some ultra violet light to pattern the cross linked resist.

Marching the habilitated wafers through a campagin of chemical developers and rinses lays siege to the walls of the activated photo resist and strips anterior metal. Lost at last, the final form is revealed, art is created. Similar techniques are utilized across contrasting fields ranging from medicine to mightily organized rivers and bridges of advanced electronic signals.

Champion Wafers Are Cut Into Smaller Chips By A Diamond Scribe

Critical Reflections

I made these chips in the winter my final year of university. This project was extraordinarily difficult and enduringly expensive. Not only were the machines and facility costs required in the range of multi millions of dollars, the time invested for this endevour to blossom priced years of youthful university forerunner experience. Only 5 out of the original 25 wafers survived the entire process, an unmerciful yield. I will always be thankful to my excellent professors for the unparalleled support, professional lessons, and personal guidance relayed unto me.
