摘要: An apparatus and method are provided for efficiently and effectively coating a substantially flat surface, i.e., a substrate, with a high-viscosity liquid chemical, such as photoresist. The flat surface is oscillated by rotating the surface in one direction and then repeatedly reversing the direction of rotation of the surface. The chemical is spread by both the centrifugal force of the rotation of the surface and the tangential force of the angular acceleration of the surface. The tangential force helps spread the chemical without prematurely overcoming the surface tension of the chemical resulting in a particularly effective coating using substantially less chemical. Chemical is alternatively spread by vibrating the flat surface. Vibrating applies to the chemical, in addition to radial, centrifugal force, if any, non-radial forces which are not directly opposed by surface tension. The chemical is therefore spread more evenly and efficiently without overcoming the surface tension of the chemical. Vibrating is accomplished either (i) by oscillating the surface with a low amplitude and a high frequency or (ii) by quickly moving the surface in a small, circular motion.

摘要: A substrate photolithography system includes a substrate handling robot that pivots about a fixed point and transfers substrates between photoresist coater, a developer, and a heating/cooling unit, all of which are clustered about the robot. The end effector of the robot is capable of both vertical and lateral movement so that individual modules of the heating/cooling unit may be stacked. For heating/cooling, the substrate is placed in the heating/cooling unit in close proximity to a hotplate/chillplate and a thermally conductive, non-reactive gas, such as helium, is introduced into the airspace between the substrate and the hotplate/chillplate. The thermally conductive, non-reactive gas, is preheated/precooled before introduction into the airspace between the substrate and the hotplate/chillplate when the gas passes through a bore in the hotplate/chillplate. Additionally, the substrate is automatically aligned in a milled recession in the hotplate surface for future handling.

摘要: A substrate photolithography system includes a substrate handling robot which pivots about a fixed point and transfers substrates between photoresist coater, a developer, and a heating/cooling unit, all of which are clustered about the robot. The end effector of the robot is capable of both vertical and lateral movement so that individual modules of the heating/cooling unit may be stacked. An apparatus and a method for baking and cooling silicon substrates are disclosed. Both baking and cooling of silicon substrates are done in a single integrated thermal process module. Each thermal process module includes two hot plate assemblies, a cool plate assembly, two local linear transfer arms and a micro-processor based module controller. Both transfer arms are capable of transferring substrates among the cool and hot plate assemblies. A cassette input/output unit handles cassettes which contain semiconductor wafers or other substrates that are to be delivered to or withdrawn from a semiconductor processing system. The input/output unit includes a drawer front which rotates 90.degree. about a horizontal axis as it is opened.
