High-density DNA probe arrays offer a massively parallel approach to nucleic acid sequence analysis that will have a major impact on gene-based biomedical research and clinical diagnostics. Light-directed synthesis has enabled the large- scale manufacture of arrays containing hundreds of thousands of oligonucleotide probe sequences on a glass `chip' about 1.6 cm2 in size. This method is used to produce high- density GeneChipTM probe arrays, which are now finding widespread use in the detection and analysis of mutations and polymorphisms (`genotyping'), and in a wide range of gene expression studies. This paper will discuss methods for high-resolution photolithographic array fabrication which integrate solid-phase oligonucleotide synthesis, photochemically removable protecting groups, and lithographic techniques adapted from the microelectronics industry.
