This is a three-chamber tool for etching of a variety of materials.
This is a single-chamber tool for etching of a variety of materials. The chamber is configured as an ICP etching tool with 1250 W ICP power, 600 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 Cl<sub>2</sub>, BCl<sub>3</sub>, CF<sub>4</sub>, CHF<sub>3</sub>, SF<sub>6</sub>, Ar, N<sub>2</sub>, He, and O<sub>2</sub> for gas sources and can be used to etch a variety of materials from SiO<sub>2</sub> to metals to compound semiconductors. The chamber evacuated with a 2000 lpm Osaka Vacuum magnetically levitated turbo pump, allowing for fast pump down. The system accepts 6” wafers (JEIDA Std) or pieces mounted to the wafers.

The system can be used to etch a variety of materials from SiO<sub>2</sub> 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 CF<sub>4</sub> and O<sub>2</sub> 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 that is not used/offline.

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 heat-sinking.

In Automatic mode, multiple wafers can be run through automatically with the cassette-based system.

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 dedicated gas sources: Cl2, BCl3, and O2

The chamber also has the following gas sources, where two of the lines must be manually switched between the two options shown (gasses can't be used simultaneously): N2/He, CHF3/Ar and CF4 /SF6

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 that is not used/offline.

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 heat-sinking.

In Automatic mode, multiple wafers can be run through automatically with the cassette-based system.
