Unfortunately, they are not used yet. Fabrication problems are the biggest issue (pure diamond is very hard and brittle and diamond film on silicon builds up internal strain causing spontaneous fracturing).
Carbon in the form of either diamond or nanotubes is currently being heavily researched as a possible semiconductor material both because it can operate at junction temperatures as high as 600C and at higher switching speeds both far exceeding other semiconductor materials.
Diamond chips can always be used for finishing and polishing other diamonds.
The term 'prototype' and the term 'diamond chips' aren't really connected, since diamond chips are the result of cutting and polishing a diamond stone. Prototype implies something designed and fashioned; diamond chips don't fit into that definition.
Diamond chips do have some value they are used in high performance commercial drills.
Not usually, although you can buy them online.
Your answer depends on the chips. Some chips can only be used as abrasives to cut and polish other diamonds; other chips -- rather large chips -- can be cut and polished into smaller gemstones. Every diamond is valued individually by its cut, clarity, carat weight and colour.

Silicon is the non-metal used to make micro-chips for computers/electronics.
silicon and germanuim are the two metalloid elements that are used to make computer chips
Second generation computers were used during this period..
Copper is used in computers for wiring and heat dissipation, but it is not the main metal. The main metals in computers are silicon, aluminum, and steel. Silicon is used in computer chips, aluminum in the casing, and steel for structural support.
I have no idea YOU KNOW WHAT THIS WEBSITE IS USELESS
Not at all, except for the first few computers I used (which were built with discrete germanium transistors) every machine I used was built using silicon chips. If the first computer you used was in the 1980s or later, you probably never saw a machine that wasn't entirely silicon chips. Even the germanium transistor machines ran about the same as modern computers, except the I/O which was usually very mechanical.
