PVD TARGET DESIGN AND SEMICONDUCTOR DEVICES FORMED USING THE SAME
A physical vapor deposition (PVD) target for performing a PVD process is provided. The PVD target includes a backing plate and a target plate coupled to the backing plate. The target plate includes a sputtering source material and a dopant, with the proviso that the dopant is not impurities in the sputtering source material. The sputtering source material includes a diffusion barrier material.
Film formation apparatus and film formation method
There is provided a film formation apparatus which forms a film on a substrate by sputtering. The apparatus comprises: a substrate holder configured to hold the substrate; and a plurality of cathodes configured to hold targets that emit sputtered particles, and connected to a power supply. At least one of the plurality of cathodes holds the targets of a plurality of types.
IN SITU AND TUNABLE DEPOSITION OF A FILM
A method is provided. The method includes the following steps: introducing a first physical vapor deposition (PVD) target and a second PVD target in a PVD system, the first PVD target containing a boron-containing cobalt iron alloy (FeCoB) with an initial boron concentration, and the second PVD target containing boron; determining parameters of the PVD system based on a target boron concentration larger than the initial boron concentration; and depositing a FeCoB film on a substrate according to the parameters of the PVD system.
MANUFACTURING METHOD OF GALLIUM NITRIDE FILM
A method for manufacturing a gallium nitride film includes the steps of placing a substrate so as to face a target containing nitrogen and gallium in a vacuum chamber, supplying a sputtering gas into the vacuum chamber, supplying a nitrogen radical into the vacuum chamber, generating a plasma of the sputtering gas by application of a voltage to the target, generating a gallium ion by a collision of an ion of the sputtering gas with the target, and stopping the application of the voltage to the target and depositing gallium nitride on the substrate. The gallium nitride is generated by a reaction of the gallium ion with a nitrogen anion which is generated by a reaction of an electron in the vacuum chamber with the nitrogen radical.
High efficiency rotatable sputter target
A rotatable sputtering target is provided for use in a sputtering system having a plurality of hollow sleeves of sputtering material arranged on a hollow e backing tube so as to form an annular space that is occupied by a bonding agent and a thermally conductive element which is a woven metal mesh.
GARNET COMPOUND, SINTERED BODY AND SPUTTERING TARGET CONTAINING SAME
A garnet compound represented by a general formula (I): Ln.sub.3In.sub.2Ga.sub.3-XAl.sub.XO.sub.12 (I) (in the formula, Ln represents one or more metal elements selected from La, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu; and X satisfies an expression 0≤X<3).
Sputtering system with a plurality of cathode assemblies
A magnetron sputtering system includes a substrate mounted within a vacuum chamber. A plurality of cathode assemblies includes a first set of cathode assemblies and a second set of cathode assemblies, and is configured for reactive sputtering. Each cathode assembly includes a target comprising sputterable material and has an at least partially exposed planar sputtering surface. A target support is configured to support the target in the vacuum chamber and rotate the target relative to the vacuum chamber about a target axis. A magnetic field source includes a magnet array. A cathode assemblies controller assembly is operative to actuate the first set of cathode assemblies without actuating the second set of cathode assemblies, and to actuate the second set of cathode assemblies without actuating the first set of cathode assemblies.
Garnet compound, sintered body and sputtering target containing same
A garnet compound represented by a general formula (I): Ln.sub.3In.sub.2Ga.sub.3-XAl.sub.XO.sub.12 (I) (in the formula, Ln represents one or more metal elements selected from La, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu; and X satisfies an expression 0≤X<3).
Paste method to reduce defects in dielectric sputtering
Embodiments of a tantalum (Ta) target pasting process for deposition chambers using RF powered processes include pasting at least a portion of the inner surfaces of the process chamber with Ta after using RF sputtering to deposit dielectric material on a wafer. Pressure levels within the process chamber are adjusted to maximize coverage of the Ta pasting layer. The Ta pasting encapsulates the dielectric material that has been inadvertently sputtered on the process chamber inner surfaces such as the shield. Oxygen is then flowed into the process chamber to form a tantalum oxide layer on the Ta pasting layer to further reduce contamination and particle generation.
SPUTTERING TARGET
A sputtering target is a sputtering target including aluminum and either a rare earth element or a titanium group element or both a rare earth element and a titanium group element, and the sputtering target has a chlorine content of 100 ppm or less.
