A semiconductor processing system includes a semiconductor processing chamber constructed of a main body, a window support member, and a window. The window support member is located over an opening into the main body. The window is located over the window support component. At least one radiation passage is formed in the window support component. The radiation passage has a first end which is open to the internal dimensions of the main body and a second end, opposing the first end, which terminates against the window.

A precursor used for labeling hepatocyte receptors and applied to radiotracers for imaging or pharmaceutical compositions for liver cancers is revealed. The precursor is a bifunctional compound. The bifunctional group includes a trisaccharide structure and a diamide dimercaptide (N2S2) ligand. The trisaccharide has high affinity to asialoglycoprotein receptors (ASGPR) on surfaces of hepatocytes while N2S2 ligand reacts with radioisotopes to form neutral complexes. Thus the precursor stays on surfaces of hepatocytes to provide radioisotope labeling or treatment effect of liver cancers.

摘要:
A method for preparing a precursor used to label hepatocyte receptors is revealed. The precursor contains a bifunctional structure including trisaccharide and DTPA ligand. During synthesis processes of the precursor, silica gel columns and Reverse phase-18 (RP-18) columns are used for purification. Thus both the purification times and cost of each purification are reduced. Moreover, use diethyl ether to facilitate precipitation of products and remove a part of coupling reagent. Removing the coupling reagent helps purification of products. Furthermore, Nα,Nα-bis(carboxymethyl)-L-lysine hydrate and benzyl chloroformate are coupled to form a trisaccharide skeleton so as to ensure the yield rate of trisaccharide structure.

The present invention relates to a method of forming copper nanowires with a metallic coating. In a preferred embodiment, the metallic coating is copper. Due to the metal coating, the nanowires become magnetically guidable and chemically stable. As such, the nanowires can be used to form nanomesh. Further, the nanowire and nanomesh of the present invention can be used as transparent electrodes that are used in TV, PC, touch-control, and solar industries.
摘要:
A control system and method for controlling two motors determining the azimuthal and circumferential position of a magnetron rotating about the central axis of the sputter chamber in back of its target sputtering and capable of a nearly arbitrary scan path, e.g., with a planetary gear mechanism. A system controller periodically sends commands to the motion controller which closely controls the motors. Each command includes a command ticket, which may be one of several values. The motion controller accepts only commands having a command ticket of a different value from the immediately preceding command. One command selects a scan profile stored in the motion controller, which calculates motor signals from the selected profile. Another command instructs a dynamic homing command which interrogates sensors of the position of two rotating arms to determine if the arms in the expected positions. If not, the arms are rehomed.

Embodiments of the invention provide processes for vapor depositing tungsten-containing materials, such as metallic tungsten and tungsten nitride. In one embodiment, a method for forming a tungsten-containing material is provided which includes positioning a substrate within a processing chamber containing a lid plate, heating the lid plate to a temperature within a range from about 120° C. to about 180° C., exposing the substrate to a reducing gas during a pre-nucleation soak process, and depositing a first tungsten nucleation layer on the substrate during a first atomic layer deposition process within the processing chamber. The method further provides depositing a tungsten nitride layer on the first tungsten nucleation layer during a vapor deposition process, depositing a second tungsten nucleation layer on the tungsten nitride layer during a second atomic layer deposition process within the processing chamber, and exposing the substrate to another reducing gas during a post-nucleation soak process.

Embodiments of the invention provide apparatuses for vapor depositing tungsten-containing materials, such as metallic tungsten and tungsten nitride. In one embodiment, a processing chamber is provided which includes a lid assembly containing a lid plate, a showerhead, a mixing cavity, a distribution cavity, and a resistive heating element contained within the lid plate. In one example, the resistive heating element is configured to provide the lid plate at a temperature within a range from about 120° C. to about 180° C., preferably, from about 140° C. to about 160° C., more preferably, from about 145° C. to about 155° C. The mixing cavity may be in fluid communication with a tungsten precursor source containing tungsten hexafluoride and a nitrogen precursor source containing ammonia. In some embodiments, a single processing chamber may be used to deposit metallic tungsten and tungsten nitride materials by CVD processes.
摘要:
The present invention discloses a scheduling method for remote object procedure call and system thereof, by a two-phase scheduling mechanism to deal with the stateful and stateless invocations simultaneously. First, plural stateful invocations in a workflow are grouped into plural groups of stateful tasks. Then, the groups of stateful tasks are assigned to the server with the minimum load. Next, the rank of each of the stateful and stateless invocations is determined to form a scheduling sequence. An estimated finish time for each stateless invocation for each server is calculated and the stateless invocation is assigned to the server with the minimum estimated finish time.
摘要:
Multiple levels of interlocks are provided relative to gas flow for a chemical vapor deposition chamber. When a chamber lid used for normal processing is in place, no interlock is in effect. When a lid used during maintenance operations is in place, flow of toxic gas to the chamber is interlocked, but flow of purge gas is permitted. When no lid is in place, all gas flow to the chamber is interlocked. The interlock arrangement may be implemented with two switches, both of which are actuated when the lid for normal processing is in place, and only one of which is actuated by the lid for the maintenance process.
