System and method for aligning a mask with a substrate
An alignment module for positioning a mask on a substrate comprises a mask stocker, an alignment stage, and a transfer robot. The mask stocker houses a mask cassette that stores a plurality of masks. The alignment stage is configured to support a carrier and a substrate. The transfer robot is configured to transfer one of the one or more masks from the mask stocker to the alignment stage and position the mask over the substrate. The alignment module may be part of an integrated platform having one or more transfer chambers, a factory interface having a substrate carrier chamber and one or more processing chambers. A carrier may be coupled to a substrate within the substrate carrier chamber and moved between the processing chambers to generate a semiconductor device.
Substrate treatment apparatus
A substrate treatment apparatus includes a transport part to transport a transparent rectangular substrate, a substrate support part to support the substrate, light generators to irradiate two different lights onto the moving substrate, and sense the irradiated lights, and a controller to determine a posture of the substrate with reference to the sensed lights and control the transport part such that the substrate is seated on the substrate support part in a default posture that is preset. The controller determines the posture of the transparent rectangular substrate with respect to the default posture using a time difference between a time point at which a first light of the two different lights is not transmitted through an edge of the transparent rectangular substrate and a time point at which a second light of the two different lights is not transmitted through the edge of the transparent rectangular substrate.
WAFER ALIGNMENT APPARATUS AND METHOD FOR MULTI-CASSETTE LOAD PORT
A method of a handling semiconductor wafers in a space of a semiconductor wafer processing facility includes: loading a cassette containing at least one semiconductor wafer into a storage buffer of a load port; measuring, from within the storage buffer, a position of a selected at least one semiconductor wafer being retrieve from the cassette residing in the storage buffer; and determining, at least in part based on said measuring, a variation of the position of the selected semiconductor wafer from a nominal position.
TRANSPORT SYSTEM AND DETERMINATION METHOD
A transport system includes a robot, sensors (an aligner sensor, a protrusion detecting sensor) and a controller.
