In the exposure and development of available deep ultraviolet (DUV) sensitive photoresist it has been observed that following the standard prior art methods of exposure and development results in a high density of undesirable remnants (denoted as Blob Defects) of various components of photoresist material remaining on the semiconductor substrate (body). A method of exposing and developing the photoresist material which results in a reduced incidence of these Blob Defects consists of using a Puddle Development technique to develop the photoresist material, and subsequently exposing the semiconductor wafer to at least one Puddle Rinse cycle which uses water.
