About
This is a three-chamber tool for etching of a variety of materials.
Chamber one "Etch Chamber" is configured as an ICP etching tool with 1000 W ICP power, 500 W RF substrate power, and RT - 80°C operation with back-side He cooling and an electrostatic chuck to maintain controlled surface temperatures during etching.
This chamber has the following gas sources: Cl2, BCl3, N2, and O2 (CHF3 or Ar), (CF4 or SF6), where two of the lines must be manually switched between the two options shown (gasses can't be used simultaneously).
The system can be used to etch a variety of materials from SiO2 to metals to compound semiconductors. The chamber is evacuated with a 2000 lpm Osaka Vacuum magnetically levitated turbo pump, and is load-locked for fast pump down.
The in-situ laser monitor installed on the etch chamber allows for repeatable etches and endpoint detection via continuous optical monitoring of the wafer reflectivity in a user-determined location, through a porthole on the chamber.
Chamber two, "Ashing Chamber" is a 2000 W ICP chamber configures for plasma "ashing" of photoresist and other materials such as BCB. The substrate is not biased for isotropic etching, and the chamber has CF4 and O2 for the gases. This is especially well-suited for omni-directional etching of photoresist/PR removal, or BCB etch-back.
Chamber three "Rinse Chamber" is a DI rinsing chamber for rinsing off any etch byproducts before removing the sample from the system.
The system accepts 6” wafers with SEMI-std. flats. Users often mount smaller pieces to the wafers, usually with easily removable oil to improve uniform heatsinking. In Automatic mode, multiple wafers can be run through automatically with the cassette-based system.
