    Abstract: Embodiments of the present invention relate to implanting arsenic into a wafer to quickly detect if there is metal contamination, such as iron, aluminum, or manganese, on the wafer. In accordance with an aspect of the present invention, a method for detecting metal contamination of a silicon chip comprises implanting arsenic ions into the silicon chip, and etching the silicon chip with a chemical etching solution. The existence of any metal contamination is detected by observing occurrence of silicon pits on the silicon chip caused by reaction between the arsenic ions and the metal contamination and etching with the chemical etching solution.

    Abstract: An apparatus and a method for preventing etch rate drop after a machine idle time in a plasma etch chamber are disclosed. In the apparatus, an enclosure for enclosing a top plate in the plasma etch chamber is provided which is equipped with a heater in fluid communication with the enclosure. The top plate which includes a dielectric window and an inductive coil can be heated to a temperature between about 35.degree. C. and about 45.degree. C. during machine idle time to prevent etch rate drop after the chamber is restarted. The plasma etch chamber may be an inductively coupled RF plasma etcher. The heater may be constructed by a heater housing which is in fluid communication with the enclosure, at least one heating lamp in the housing, and a blower for delivering heated air into the enclosure cavity. By utilizing the present invention novel apparatus and method, etch rate can be substantially maintained even after a machine idle time and an under-etch condition can be prevented to substantially eliminate scrap of defective wafers.

    Abstract: A method for earthquake-proof mounting a semiconductor process machine on a removable floor (or a raised floor) in a semiconductor fabrication plant. In the method, a modified I-beam which has a horizontally extending upper flange is provided for mounting under a removable floor and attaching through the floor directly to a process machine situated on top of the floor. The process machine may be attached to the modified I-beam through an L-shaped bracket that is attached to the support frame of the process machine with the horizontal flange of the bracket attached to the modified I-beam through apertures in the removable floor. The present invention further comprises an earthquake-proof mounting fixture for mounting a process machine on a removable floor in a semiconductor fabrication plant. The mounting fixture consists of essentially a modified I-beam for supporting the removable floor on a non-removable floor, the I-beam is equipped with a horizontally extending upper flange for attaching to the process machine directly through the removable floor. The present invention novel method and apparatus allows a process machine to be mounted on a removable floor in a fabrication plant to meet seismic prevention regulations imposed by government agencies for environmental protection and occupational safety. The present invention novel apparatus is especially suitable for use in mounting process machines that holds hazardous, corrosive chemicals for preventing chemicals from spilling during an earthquake, especially when the process machine is mounted on a higher floor in the plant.
