Rare 1960s 1.6" Silicon Wafer - Mullard FCH211 NAND/NOR Sextuple Inverter

Description: About this Artwork:Logic chips were the first computer chips. The Mullard FCH211 logic chip was produced in the mid-1960s. The FCH211 was a NAND/NOR Sextuple Inverter Gate. The name is a mouthful, and it was a very advanced and flexible chip, providing three logic functions for 6 inputs and outputs. There are about 480 DTL Mullard FCH211 logic chips on this silicon wafer. The artwork on the front shows individual chips on the wafer. The FCH211 had 6 transistors, 15 diodes, and 6 resistors on each chip. The logic diagram to the right (on back of artwork) shows the circuit for the FCH211 logic chip. It is interesting to compare this logic diagram with the actual physical chip implementation on the front of the artwork. The input and output connections are identified on both the physical chip and the logic diagram. Unless you are versed on chip design, you might not be able to recognize the diodes, transistors, and resistors in the FCH211 chip image on the front of the artwork. The images below (on back of artwork) provide a quick legend for identifying them. On the left is a diode that allows electricity to flow in one direction. In the middle is a transistor which is an electrically controlled switch. And to the furthest right is a resistor that impedes electrical flow (in the picture the resistor is vertical, however an unrelated trace is passing over it in the center going left to right). Framing: The artwork is framed in an 8"x10" black shadow box frame, with glass. All framing materials are acid free. A narrative about the artwork that includes the artist’s signature is placed on the back of the artwork.Shipping: I ship by US Priority Mail. I combine shipping costs.

However, the silicon must be made very, very pure. The first step is to melt the sand, in a furnace that reaches about 3200o F, and mix with carbon. This first purification process creates 99% pure Silicon, a common output is Silicon Carbide. The Silicon Carbide is processed in a trichlorosilane distillation method to create 99.9999% pure silicon called polycrystalline silicon. The polysilicon is broken up into chunks. These chunks are melted in a crucible at about 2500o F. A silicon crystal seed is dipped in molten silicon and slowly drawn out to create a cylinder of silicon. These silicon cylinders are some of the purest crystals on the planet. Once the silicon cylinder is grown to the desired diameter, it is sawed into wafers. These wafers are polished to achieve a very flat mirror surface. Transistors, and other micro-electronic parts, are built on the polished wafer in layers in a process called etching. The wafer is then sawed into its individual chips. Each chip is mounted in an electronic package that serves to protect it and connect it to the outside world. It has been said that computer chips are the greatest value added product in the world. We essentially take a pile of sand and change it into thousands of dollars worth of computer chips.General Information:These artworks are the creation of ChipScapesTM artist Steve Emery. ChipScapesTM are photographs taken of computer chips, boards, and other computer artifacts. They are sort of chip landscapes, or ChipScapesTM for short. Most often a macro-lens or microscope is used with special lightning to achieve these unique artworks. Intel, IBM, Fairchild, DEC, Signetics, Intersil, AMD, Zilog, Motorola, MOS, NEC, Texas Instruments, are some of the great chip making companies. Chips like the Intel 4004, MOS 6502, Zilog Z80, AMD 2901, IBM PowerPC and others have changed the way people work and play. ChipScapesTM are dedicated to preserving and sharing these computing and communication technologies that changed the world. ChipScapesTM artworks are fine collectible artworks. ChipScapesTM come is a variety of shapes sizes and colors. Clusters of my artwork make for stunning displays! A ChipScapeTM would make a great gift for the nerd, geek, engineer, programmer, IT executive, or just that technology savvy person in your life.More Questions?For more information about ChipScapesTM, please check out my ChipScapesTM website.
