Semiconductors is another very large category, like hardware. Although you can find companies in this list that offer integrated circuits and chipsets, the primary purpose for this semiconductors page is to collect sources for discrete transistors, diodes, low circuit density analog & digital ICs, SCRs, triacs, diacs, FETs, MOSFETs, and other types of semiconductors that perform a single, simple function.
