| 摘要 |
A programmable transistor array circuit is disclosed comprising a semiconductor substrate; and a plurality of basic transistor units (BTUs) arranged in rows and columns of uniformly spaced cells, the BTUs further comprising PMOS transistor units (PTUs), NMOS transistor units (NTUs) and dummy transistor units (DTUs) each BTU having conductors arranged in a single direction running through the BTUs and the conductors being uniformly spaced with respect to each other. The arrangement of the BTUs is subject to restricted design rules. Logical transistor units (LTUs) are formed from the BTUs using first and second layers of metallization. Methods for producing integrated circuits are disclosed forming programmable transistor arrays and implementing customer specified system designs upon the programmable transistor arrays.
