  • Publication number: 20170203417
    Abstract: A pipe wrench includes a fixed jaw with alternatively located first recesses and first driving faces defined in the inner side thereof. A pivotal member is pivotably connected to the fixed jaw and a resilient member is biased between the fixed jaw and the pivotal member. The pivotal member has alternatively located third recesses and second driving faces. A hexagonal space is defined between the first and second driving faces. The end portion of the pivotal member is inserted into a second recess defined in the inner side of the fixed jaw. The object is clamped in the hexagonal space, and the pivotal member can be pivoted away from the fixed jaw. The pipe wrench is able to quickly clamp and dismounted from the object.

  • Publication number: 20170178898
    Abstract: A process tuning kit for use in a chemical deposition apparatus wherein the process tuning kit includes a carrier ring, horseshoes and shims. The horseshoes have the same dimensions and the shims are provided in sets with different thicknesses to control the height of the horseshoes with respect to an upper surface of a pedestal assembly on which the horseshoes and shims are mounted. A semiconductor substrate is transported into a vacuum chamber of the chemical deposition apparatus by the carrier ring which is placed on the horseshoes such that minimum contact area supports lift the substrate from the carrier ring and support the substrate at a predetermined offset with respect to an upper surface of the pedestal assembly. During processing of the substrate, backside deposition can be reduced by using shims of desired thickness to control the predetermined offset.

  • Publication number: 20170167017
    Abstract: Disclosed are methods of depositing films of material on semiconductor substrates employing the use of a secondary purge. The methods may include flowing a film precursor into a processing chamber and adsorbing the film precursor onto a substrate in the processing chamber such that the precursor forms an adsorption-limited layer on the substrate. The methods may further include removing at least some unadsorbed film precursor from the volume surrounding the adsorbed precursor by purging the processing chamber with a primary purge gas, and thereafter reacting adsorbed film precursor while a secondary purge gas is flowed into the processing chamber, resulting in the formation of a film layer on the substrate. The secondary purge gas may include a chemical species having an ionization energy and/or a disassociation energy equal to or greater than that of O2. Also disclosed are apparatuses which implement the foregoing processes.

  • Patent number: 9624578
    Abstract: Methods for depositing film on substrates are provided. In these embodiments, the substrates are processed in batches. Due to changing conditions within a reaction chamber as additional substrates in the batch are processed, various film properties may trend over the course of a batch. The methods herein can be used to address the trending of film properties over the course of a batch. More specifically, film property trending is minimized by changing the amount of RF power used to process substrates over the course of the batch. Such methods are sometimes referred to as RF compensation methods.

  • Publication number: 20170009346
    Abstract: Methods of depositing uniform films on substrates using multi-cyclic atomic layer deposition techniques are described. Methods involve varying one or more parameter values from cycle to cycle to tailor the deposition profile. For example, some methods involve repeating a first ALD cycle using a first carrier gas flow rate during precursor exposure and a second ALD cycle using a second carrier gas flow rate during precursor exposure. Some methods involve repeating a first ALD cycle using a first duration of precursor exposure and a second ALD cycle using a second duration of precursor exposure.

  • Publication number: 20160177443
    Abstract: The present inventors have conceived of a multi-stage process gas delivery system for use in a substrate processing apparatus. In certain implementations, a first process gas may first be delivered to a substrate in a substrate processing chamber. A second process gas may be delivered, at a later time, to the substrate to aid in the even dosing of the substrate. Delivery of the first process gas and the second process gas may cease at the same time or may cease at separate times.
