A coating and developing apparatus comprises a process block which forms a resist film on a wafer, then transfers the wafer to an exposure apparatus, and performs a developing process on the wafer after exposure, and an interface transfer mechanism provided between the process block and the exposure apparatus. The process block includes unit blocks for coating-film formation and unit blocks for development laid out in a stacked manner. When an abnormality occurs in the interface transfer mechanism, an ordinary process in the unit block for coating-film formation is performed on those substrates which are present in that unit block for coating-film formation, after which processed wafers are retreated to a retaining unit and transfer of any wafer into the unit block for coating-film formation is inhibited.

Rinsing nozzles 310a to 310e are moved on a wafer W while they are discharging rinsing solution 326. At that point, discharging openings 317a to 317e are contacted to developing solution 350 coated on the wafer W or rinsing solution 326 on the wafer W. Thus, the impact against the wafer W can be suppressed. As a result, pattern collapse can be prevented. In addition, a front portion of the developing solution 350 can push away the developing solution 350.

A high-speed digital photographic printing system and method includes image-specific backprinting and automatic tracking and sorting of printed jobs. The system includes one or more photographic printers, where each printer can have a different printing rate. A scheduler schedules printing orders to the different printers. The printer-independent image rendering is conducted asynchronous to the printing to maximize the printing throughput. In some embodiments, the rendering image processor does the vast majority of the image processing and outputs a printer-independent data file (generally much larger than the source image data file) that requires little if any further data manipulations or processing in the exposure unit.

A pretreatment process, carried out prior to a developing process, spouts pure water, namely, a diffusion-assisting liquid for assisting the spread of a developer over the surface of a wafer, through a cleaning liquid spouting nozzle onto a central part of the wafer to form a puddle of pure water. The developer is spouted onto the central part of the wafer for prewetting while the wafer is rotated at a high rotating speed to spread the developer over the surface of the wafer. The developer dissolves the resist film partly and produces a solution. The rotation of the wafer is reversed, for example, within 7 s in which the solution is being produced to reduce the water-repellency of the wafer by spreading the solution over the entire surface of the wafer. Then, the developer is spouted onto the rotating wafer to spread the developer on the surface of the wafer.

An image recording surface of an exposed instant film is held so as to face an optical head module. Read light (white light) emitted from a light source passes a transparent portion of a color-separation filter, a first mirror, a first graded-index-type optical fiber array, and a second mirror in order. Then, the read light is radiated toward an instant film from an opening of the optical head module. The second mirror is set to a read position where the read light is inclined by a predetermined angle relative to the instant film. The read light is reflected by the image recording surface of the instant film and enters a line-CCD sensor via a second graded-index-type optical fiber array. By moving the optical head module in a sub-scanning direction, it is possible to read an image from the instant film.
