摘要:
A plasma ashing apparatus has a vacuum treatment chamber for receiving therein a substrate coated with a resist film, a reactive gas introduction pipe equipped with a plasma applicator, a vacuum exhaust pipe, a heating means for heating the substrate, and two pieces of electrodes disposed in parallel to each other. One of the electrodes is a substrate electrode and the other thereof is a circular counter electrode. These two electrodes are commonly connected to an RF power source to thereby constitute a cathode electrode. Multiple concentric perforations are formed in the counter electrode except for a rib portion. A central perforation is formed in the center of the counter electrode. The concentric perforations are formed at every distance, from the center, equivalent to a diameter of the central perforation, while leaving circular electrode surfaces corresponding in width to a radius of of the perforation.
摘要:
Process and apparatus for carrying out a reaction, such as etching aluminum, in the glow discharge of a gas plasma. The plasma is formed between a pair of closely spaced electrodes, and a distributed impedance is provided in series with the plasma to assure uniform distribution of the ionizing current and the glow discharge of the plasma throughout the region between the electrodes.
摘要:
A method for removing a resist layer, particularly in via holes, includes plasma to remove organic compounds, rinsing the device in deionized water, and sputtering with argon to remove inorganic compounds. The order of rinsing and sputtering can be reversed. These methods avoid the use of acids and industrial solvents.
摘要:
A method for removing a resist layer includes an RIE process and a downstream microwave process, each performed such that the temperature of the wafer is no greater than about 60.degree. C. By performing these processes cold, the resist need not be pre-heated to drive off solvents. The RIE process and the microwave process can be performed sequentially or simultaneously.
摘要:
Gas plasma process and gas mixture useful for the removal of materials in the manufacture of semiconductor devices. Substrate wafers or other semiconductor devices are exposed to a gaseous plasma containing SiF.sub.4 or SiF.sub.4 and oxygen for a time sufficient to effect a desired removal of material from the wafer or device. The process and gas are particularly suitable for selective etching of Si.sub.3 N.sub.4 and the stripping of photoresist, as well as the etching of materials such as silicon and compounds containing silicon.

摘要:
In a microwave downstream process, a microwave plasma is formed from a gas that has a small quantity of fluorine to enhance ashing without substantial oxide loss. This process can be performed before or after other microwave downstream processes or reactive ion etching processes.
摘要:
Plasma etching device and process in which a chamber is divided into two regions by a perforated screen. Objects to be etched are placed in one region, and a plasma is formed in the other region. Etching occurs in the first region, and structure is included for heating the etched objects in the first region to facilitate the removal of photoresist used to define the areas to be etched.
摘要:
A method and apparatus for dry processing of a substrate is provided. More particularly, a substrate is exposed to a gas, such as an effluent from a gas plasma, having at least one reactive specie, such as a free radical, the gas having substantially no electrically charged particles present. Simultaneously, the substrate is irradiated with ultraviolet radiation to enhance the reaction rate in a controlled manner. Also provided is a means for irradiating the wafer with infrared radiation to heat the wafer independently of the irradiation with ultraviolet radiation.
摘要:
A method is provided for removing photoresist from a substrate, wherein the method comprises producing a gas plasma from a gas mixture comprising oxygen, CF.sub.4, nitrogen, and hydrogen; substantially eliminating any electrically charged particles from the plasma to produce a plasma effluent; heating the substrate to a temperature in the range of from about 250 to 300 degrees Centigrade; exposing the substrate and photoresist thereon to the effluent while said temperature is maintained; and simultaneously with the exposure step, irradiating the substrate with collimated ultraviolet radiation.
摘要:
This invention relates to an apparatus and process for the uniform dry process treatment of the surface of a substrate. More particularly, the invention relates to an apparatus and process wherein a gas plasma composition having at least one reactive specie is supplied through a first inlet port into a chamber means containing the substrate to be treated. A second gas is also supplied into the chamber through a second inlet port thereby redirecting the gas plasma composition into contact with the substrate in a substantially uniform manner.
