Abstract:
A method of treating an anti-reflective coating on a substrate. The method includes exposing the anti-reflective coating to a dosage of ultraviolet radiation sufficient to result in the removal of at least a portion of the anti-reflective coating resulting in reduced ARC etch process time and reduced damage to photoresist during one etch.
Abstract:
Material that has previously been subjected to a removal treatment is removed from a substrate by being contacted with a gas containing an excited halogen at a pressure of greater than 50 torr.
Abstract:
A high power lamp (2) that may be either an electrodeless or arc lamp is disclosed. The lamp contains a fill of either selenium or sulfur and a small amount of rare gas (e.g. argon or xenon).
Abstract:
The spectral energy characteristic of a discharge lamp is controlled by changing the density of the fill substance. The spectral characteristic can be shifted while substantially maintaining its shape by changing the density of the fill. A sulfur or selenium containing discharge lamp which is operated at a pressure of at least about 1 atmosphere contains a low ionization potential substance in the fill. Characteristics which are improved are one or more of spatial color uniformity, extinguishing characteristics, and bulb starting reliability. Particular substances which are added to the fill are alkali metal containing substances, III B metal containing substances, and alkaline earth metal containing substances. When light is reflected back into the bulb, the light which is re-emitted is stronger in the higher wavelengths.
Abstract:
A method of removing material from a substrate (88), and a plasma discharge device wherein a plasma is excited by microwave energy (91, 93, 95, 97) having an electric field which is azimuthally and axially uniform in relation to the plasma tube (40). The microwave cavity is divided longitudinally into sections by conducting partitions (44, 45, 46), each of which is separately fed with microwave energy (91, 93, 95, 97), and the plasma tube (40) extends through openings in the partitions (44, 45, 46).
Abstract:
A magnetron power supply prevents high level mode current, varies a power output level and prevents moding of the magnetron (8). To limit excessive anode current, a transformer (26) includes an air gap located between primary and secondary windings and a shunt of high magnetic permeability adjacent the air gap. When the magnetron (8) starts conducting, the secondary winding becomes heavily loaded. Some of the flux overcomes the magnetic permeability and passes through the shunt and the resulting current becomes diverted from the secondary winding to reduce the high level anode current. A microprocessor (46) senses anode (36) current and voltage of the magnetron (8) for adjusting the conduction angle of a thyristor (22) to obtain the desired power level and monitors the anode (36) voltage for detecting moding of the magnetron (8). If moding is detected, the microprocessor (46) adjusts the conduction angle of another thyristor (38) to change the current supplied to the filament (34).
Abstract:
A method for removing material from a substrate. A plasma is generated in a plasma generating and discharge device including a sapphire plasma tube (40). At least one fluorine-containing compound is introduced into the plasma. A forming gas is introduced into the plasma. The plasma is directed toward the material to be removed from the substrate (88).
Abstract:
An electrodeless lamp bulb (12) is rotated at sufficient rate to obviate isolated discharges. A coaxially excited electrodeless lamp bulb (12) is rotated in such manner that different regions of the bulb are near the high field region caused by the inner coaxial conductor, thus preventing arc attachment from occurring. An electrodeless lamp bulb (12) is rotated at a high speed sufficient to improve lamp efficiency and reduce cooling requirement. An electrodeless lamp bulb (12) is provided with wall of reduced thickness at the area of the bulb (12) where it is desired to condense the fill upon turning off the power, thus providing for quicker starting.
