摘要:
Systems and methods for plasma processing of microfeature workpieces are disclosed herein. In one embodiment, a method includes generating a plasma in a chamber while a microfeature workpiece is positioned in the chamber, measuring optical emissions from the plasma, and determining a parameter of the plasma based on the measured optical emissions. The parameter can be an ion density or another parameter of the plasma.

Systems and methods for plasma doping microfeature workpieces are disclosed herein. In one embodiment, a method of implanting boron ions into a region of a workpiece includes generating a plasma in a chamber, selectively applying a pulsed electrical potential to the workpiece with a duty cycle of between approximately 20 percent and approximately 50 percent, and implanting an ion specie into the region of the workpiece.

Some embodiments include methods of forming one or more doped regions in a semiconductor substrate. Plasma doping may be used to form a first dopant to a first depth within the substrate. The first dopant may then be impacted with a second dopant to knock the first dopant to a second depth within the substrate. In some embodiments the first dopant is p-type (such as boron) and the second dopant is neutral type (such as germanium). In some embodiments the second dopant is heavier than the first dopant.

A hinge assembly (200) includes a housing (12), a shaft (11), a fixing pin (14), a transposition mechanism (13) and a first spring (16). The housing has a circumferential wall defining a manual slot (121) and an automatic slot (123). Each of the manual slot and the automatic slot runs through a circumferential wall thereof. The shaft defines a pin hole (1141), and the shaft is engaged in the housing. The fixing pin passes through the pin hole of the shaft. One end of the fixing pin is alternatively received in the manual slot or the automatic slot. The transposition mechanism is configured for switching the pin from the manual slot to the automatic slot. The first spring provides an elastic force causing the housing to move relative to the shaft when the pin breaks away from the manual slot.

A battery cover latching mechanism (300) is used in a portable electronic device. The portable electronic device has a housing (10) and a battery cover (20). The battery cover latching mechanism comprises a fixing portion (206) formed on the battery cover, a locking member (30) and a switch (40). The locking member is mounted on the housing and slidable between a first position where the locking member engages with the housing and the battery cover and a second position where the locking member detaches with the housing and the battery cover relative to the housing. The switch is rotatably mounted on the housing. The switch engages with the locking member. The rotation of the switch urges the locking member to slide from the first position to a second position.

One embodiment of a method for forming a low-k dielectric for a semiconductor device assembly comprises forming a silicon dioxide layer, then forming a patterned masking layer such as silicon nitride on the silicon dioxide. Using the patterned nitride layer as a pattern, the silicon dioxide is etched to form a plurality of hemispherical microcavities in the silicon dioxide. Openings in the patterned nitride are filled, then another layer is formed over the silicon nitride layer using the silicon nitride as a support over the microcavities. An inventive structure resulting from the method is also described.

The present invention is directed to a method for clamping and processing a semiconductor substrate using a semiconductor processing apparatus. According to one aspect of the present invention, a multi-polar electrostatic chuck and associated method is disclosed which provides heating or cooling of a substrate by thermal contact conduction between the electrostatic chuck and the substrate. The multi-polar electrostatic chuck includes a semiconductor platform having a plurality of protrusions that define gaps therebetween, wherein a surface roughness of the plurality of protrusions is less than 100 Angstroms. The electrostatic chuck further includes a voltage control system operable to control a voltage applied to the electrostatic chuck to thus control a contact heat transfer coefficient of the electrostatic chuck, wherein the heat transfer coefficient of the electrostatic chuck is primarily a function of a contact pressure between the substrate and the plurality of protrusions.
