    摘要: The present invention provides a method and an apparatus for improving the etch uniformity across a substrate during a plasma etch process that employs the use of an inductively coupled plasma helical inductor. The plasma apparatus comprising a vacuum chamber, a support member in the vacuum chamber for holding the substrate, an etchant gas supply for providing an etchant gas to the vacuum chamber, an exhaust in fluid communication with the vacuum chamber, an RF power source and a helical inductor disposed around or near a portion of the vacuum chamber. A sensor is provided for measuring a process attribute to generate a signal to a controller that then controls a mechanism that varies the position of the helical inductor so that the uniformity of the plasma etch is improved.

    摘要: The present invention provides a method for processing a photolithographic substrate, comprising the placement of the photolithographic substrate on a support member in a chamber wherein the photolithographic substrate has an initial temperature of about zero degrees Celsius to about fifty degrees Celsius. A heat transfer fluid is introduced into the chamber to cool the photolithographic substrate to a target temperature of less than about zero degrees Celsius to less than about minus forty degrees Celsius. The cooled photolithographic substrate is subjected to a plasma process before the temperature of the cooled photolithographic substrate reaches the initial temperature.

    摘要: The present invention provides a method for improving the critical dimension performance during a plasma etching process of a photolithographic substrate having a thin film. A passivation film is deposited onto the photolithographic substrate using a first set of process conditions. The deposited film is etched from the photolithographic substrate using a second set of process conditions. An exposed surface of the photolithographic substrate is etched using a third set of process conditions. During the plasma processing of the photolithographic substrate, the critical dimension performance of the photolithographic substrate is monitored to insure that the target uniformity and feature widths are obtained by adjusting the deposition and etch plasma processing of the photolithographic substrate.

    摘要: The present invention provides a method and an apparatus for reducing aspect ratio dependent etching that is observed when plasma etching deep trenches in a semiconductor substrate through an alternating deposition/etch process. A plurality of different sized features on the substrate are monitored in real time during the alternating deposition/etch process. Then, based on the information received from the monitor, at least one process parameter is adjusted in the alternating deposition/etch process to achieve equivalent etch depths of at least two different sized features on the substrate.
