Patent number: 6541170Abstract: Before forming a resist pattern, the light reflectivity of the undercoat of the wafer is measured by a reflectivity measuring unit. The conditions are controlled according to the measured reflectivity when forming the resist pattern. The conditions when forming the resist pattern are the rotation speed when supplying the resist solution while rotating the wafer inside the resist coating unit, the exposure time in the exposing unit, the developing time in the developing unit, and so forth. Thus, by controlling the conditions when forming the resist pattern according to the light reflectivity of the wafer's undercoat, a highly fine control of the line width of the resist pattern is made possible.Type: GrantFiled: June 19, 2001Date of Patent: April 1, 2003Assignee: Tokyo Electron LimitedInventors: Yuji Fukuda, Kunie Ogata

Patent number: 6313903Abstract: In a transferring region of a wafer transferring portion that transfers a wafer placed in a carrier loading and unloading portion, a pattern inspecting portion for inspecting a resist pattern and a carrier for accommodating a wafer determined as an unacceptable wafer are disposed. The carrier is conveyed to an external cleaning portion. Resist on the unacceptable wafer is cleaned and removed. The resultant wafer is loaded to the coating and developing unit. The film thickness of a monitor wafer is measured by a film thickness measuring portion disposed in the coating and developing unit. Thereafter, resist on the entire surface of the monitor wafer is removed with thinner supplied from a solvent nozzle. Thus, the monitor wafer is regenerated. Consequently, when the coating and developing unit is operated and a substrate and a monitor substrate that have been processes are inspected, the throughput of the coating and developing unit becomes high and the processes can be automatically performed.Type: GrantFiled: January 28, 2000Date of Patent: November 6, 2001Assignee: Tokyo Electron LimitedInventor: Kunie Ogata
