  • Patent number: 9954476
    Abstract: A TH terminal receives an analog control voltage VTH which indicates a rotational speed. With a first platform, a capacitor and a discharging resistor are connected in parallel between an OSC terminal and the ground. A charging resistor and a first switch are arranged in series between the OSC terminal and a reference voltage line via which a stabilized voltage is supplied. When an oscillator voltage VOSC that occurs at the OSC terminal reaches an upper-side threshold VH, a switching circuit turns off the first switch. When the oscillator voltage VOSC falls to a lower-side threshold value VL, the switching circuit turns on the first switch. The oscillator voltage VOSC is compared with the voltage at the TH terminal, so as to generate a pulse-modulated control pulse S3.

  • Patent number: 9711365
    Abstract: Pretreatment of an etch chamber for performing a silicon etch process and Bosch process can be effected by running a deposition process employing C5HF7, or by running an alternating deposition and etch process employing C5H2F6 and SF6. It has been discovered that the pretreatment of the etch chamber for the silicon etch process can enhance the etch rate of silicon by at least 50% without adverse effect on etch profile during a first each process following the pretreatment, while the etch rate enhancement factor decreases over time. By periodically performing the pretreatment in the etch chamber, the throughput of the etch chamber can be increased without adversely impacting the etch profile of the processed substrates.

  • Publication number: 20170194497
    Abstract: A silicon nitride cap on a gate stack is removed by etching with a fluorohydrocarbon-containing plasma subsequent to formation of source/drain regions without causing unacceptable damage to the gate stack or source/drain regions. A fluorohydrocarbon-containing polymer protection layer is selectively deposited on the regions that are not to be etched during the removal of the nitride cap. The ability to remove the silicon nitride material using gas chemistry, causing formation of a volatile etch product and protection layer, enables reduction of the ion energy to the etching threshold.

  • Patent number: 9633948
    Abstract: A stack that includes, from bottom to top, a nitrogen-containing dielectric layer, an interconnect level dielectric material layer, and a hard mask layer is formed on a substrate. The hard mask layer and the interconnect level dielectric material layer are patterned by an etch. Employing the patterned hard mask layer as an etch mask, the nitrogen-containing dielectric layer is patterned by a break-through anisotropic etch, which employs a fluorohydrocarbon-containing plasma to break through the nitrogen-containing dielectric layer. Fluorohydrocarbon gases used to generate the fluorohydrocarbon-containing plasma generate a carbon-rich polymer residue, which interact with the nitrogen-containing dielectric layer to form volatile compounds. Plasma energy can be decreased below 100 eV to reduce damage to physically exposed surfaces of the interconnect level dielectric material layer.
