One aspect of the present invention relates to a system for dissipating electrostatic charge on a mask plate structure containing the mask plate structure containing a substrate, a chromium layer over the substrate, and a conductive polymer over the chromium layer; a conductive structure coupled to the mask plate structure which allows accumulated electrostatic charge to flow from the mask plate structure; a conductive path between the conductive structure and a ground, wherein the conductive path inacludes a switch controlled by a controller; and a detector coupled to the controller for signaling the controller when the accumulation of electrostatic charge is detected. Another aspect of the present invention relates to a method for dissipating charge accumulation during patterning of mask plates using a conductive polymer layer involving the steps of providing a mask substrate having a chromium layer; depositing a conductive polymer layer over the chromium layer; connecting a conductive structure to the mask substrate; irradiating portions of the mask substrate with an electron beam; detecting whether electrostatic charge exists on the mask substrate; and if electrostatic charge is detected, closing a circuit whereby the conductive structure is grounded to permit a flow of electrostatic charge from the mask substrate to the ground.

In one embodiment, the present invention relates to a method of treating a resist layer involving the steps of providing the resist layer having a first thickness, the resist layer comprising a polymer having a labile group; contacting a coating containing at least one cleaving compound with the resist layer to form a deprotected resist layer at an interface between the resist layer and the coating; and removing the coating and the deprotected resist layer leaving a resist having a second thickness, wherein the second thickness is smaller than the first thickness.
摘要:
Systems and/or methods are disclosed for measuring and/or controlling an amount of impurity that is dissolved within an immersion medium employed with immersion lithography. The impurity can be photoresist from a photoresist layer coated upon a substrate surface. A known grating structure is built upon the substrate. A real time immersion medium monitoring component facilitates measuring and/or controlling the amount of impurities dissolved within the immersion medium by utilizing light scattered from the known grating structure.

The present invention provides a system and methodology for dummy-dispensing resist though a dispense head while mitigating waste associated with the dummy-dispense process. The dummy dispensed resist is returned to a reservoir from which it was taken. Between substrate applications, the dispense head can be positioned to dispense resist into a return line. The flow of resist from the dispense head keeps resist from drying at the dispense head. By funneling the dummy-dispensed resist into a return line with low volume, for example, waste from the dummy-dispensing process can be mitigated.

One aspect of the present invention relates to a method for making a dual damascene pattern in an insulative layer in a single etch process involving providing a wafer having at least one insulative layer formed thereon; depositing a first photoresist layer over the at least one insulative layer; patterning a first image into the first photoresist layer; curing the first patterned photoresist layer; depositing a second photoresist layer over the first patterned photoresist layer; patterning a second image into the second photoresist layer; and etching the at least one insulative layer through the first patterned photoresist layer and the second patterned photoresist layer simultaneously in the single etch process.
摘要:
A system for regulating an etch process is provided. The system includes one or more light sources, each light source directing light to one or more features and/or gratings on a wafer. Light reflected from the features and/or gratings is collected by a measuring system, which processes the collected light. The collected light is indicative of the dimensions achieved at respective portions of the wafer. The measuring system provides etching related data to a processor that determines the acceptability of the etching of the respective portions of the wafer. The system also includes one or more etching devices, each such device corresponding to a portion of the wafer and providing for the etching thereof. The processor selectively controls the etching devices to regulate etching of the portions of the wafer.
