This invention provides a coating liquid for the formation of a positive electrode for a lithium rechargeable battery. This coating liquid contains a large particle diameter active material having an average particle diameter of 1 to 20 [mu]m and a small particle diameter active material having an average particle diameter of 5 to 100 nm. The mixing ratio between the large particle diameter active material and the small particle diameter active material is 90 : 10 to 50 : 50 on a volume basis, and the average particle diameter ratio (the average particle diameter of the large particle diameter active material / the average particle diameter of the small particle diameter active material) is 50 to 500. The coating liquid has an excellent long-term storage stability and can realize high-density filling of the active material in the coating liquid. Accordingly, the preparation of a positive electrode using the coating liquid can realize the provision of a lithium rechargeable battery with a high energy density and a high capacity.

The present invention provides a method and equipment for processing semiconductor wafers to reduce dimensional changes. It measures the CD and profile of the photoresist mask and the thickness of the underlying layer at multiple points on the wafer and feeds back such information to adjust the following A process (eg, etch process) of the inspected wafer to be processed. After this processing step, the dimensions of the features formed by the process, such as the CD and depth of the trenches, are measured at multiple points on the wafer and this information is fed back to the processing tool to adjust the process for the next wafer , further reducing size variations. In some embodiments, CD, profiling, thickness and depth measurements, etch processing and post-etch cleaning are performed in a single module in a controlled environment. All transfer and processing steps implemented by this module are carried out in a clean environment, thereby avoiding exposure of the wafer to the atmosphere and avoiding possible contamination between steps to increase yield.

The invention relates to a MFI structure molecular sieve containing phosphorus and transition metal as well as its preparation method. The anhydrous chemical expression of the molecular sieve is (0-0.3) Na2O.(0.5-6) Al2O3.(1.3-10) P2O5.(0.7-15) MxOy.(70-97) SiO2, wherein M is selected from one or more of Fe, Co, Ni, Cu, Mn, Zn, Sn and Bi, x is expressed as atomicity of M, y is expressed as a number which satisfies the requirement of an oxidation state of M; No characteristic absorption peak is existed at 1633cm<-1> on infrared spectrum by molecular sieve trimethylpyridine adsorption. The preparation method comprises that phosphor and transition metal are introduced in molecular sieve with the MFI structure during ammonium exchanging, wherein the phosphor introduction is divided into two parts, a part of phosphor is introduced before introducing the transition metal or at the same time with transition metal introduction, the other part of the phosphor is introduced after the transitionmetal introduction. The provided molecular sieve is used for conversing hydrocarbon oil, the yield of dry gas and coke is low, and the yield of propylene and isobutene is high.

The cell is also placed a plurality of times (606, 608, 610) in a second array. The second array is placed adjacent and offset from the first array by an offset distance (O2).

The invention discloses a positive-negative-positive (PNP) transistor integrated with a germanium-silicon hetero-junction negative-positive-negative (NPN) transistor. A base area out-leading area is arranged on the lateral face of an active area to lead out a base area so that the fact that polycrystalline silicon is formed on the top portion of the active area to lead out the base area can be avoided, and therefore the integration of the PNP transistor and the germanium-silicon hetero-junction NPN transistor can be realized without changing the manufacturing process of the germanium-silicon hetero-junction NPN transistor, influences to the manufacturing of the germanium-silicon hetero-junction NPN transistor are prevented from being produced, and the facts that manufacturing cost of germanium-silicon hetero-junction NPN transistor is not increased and yield of the germanium-silicon hetero-junction NPN transistor is not reduced are guaranteed.
