Qinhuangdao Intrinsic Crsytal Technology Co., Ltd offers a handful of standard 4" silicon wafer options, also referred to as 100mm silicon wafers, for our customer's urgent needs. These are considered stocking parts and ship from our shelf in San Jose, California and usually within the same day as the request.
As silicon wafer manufacturing technology has progressed, driven primarily by the needs of the integrated circuit "chip" manufacturers, silicon wafer sizes have gradually increased in size from 25mm silicon wafers to the current largest available diameter of 450mm silicon wafers. The larger the diameter of the silicon wafer, the larger the surface area and the more chips that can be manufactured from a single wafer. More chips per silicon wafer equals lower cost per chip for the chip maker.
As diameters have increased and the semiconductor industry has moved to the new larger diameters of silicon wafers, all of the major silicon manufacturers have ceased production of smaller diameter wafers. There are no longer any major silicon manufacturers in the world that are manufacturing 4" silicon wafers, also known as 100mm silicon wafers. This has caused a constriction of supply of 4" silicon wafers in the marketplace while creating opportunities for smaller secondary players to begin production, though not in the volumes that were manufactured in the past.
These events have conspired to make the sourcing of 4" silicon wafers a challenge yet these wafers are still critical components for Universities and Research and Development facilities around the globe. We have met the challenge and can meet your demands for 4" silicon wafers.
