Title: Modular abatement apparatus
Inventor: SEELEY ANDREW JAMES
IPC: F23G7/06
Filed: 2022-07-07
Abstract: A modular abatement apparatus and a method are disclosed. The modular abatement apparatus is for abatement of an effluent stream from a semiconductor processing tool and comprises: a housing defining a common housing chamber; a plurality of combustion chamber modules positionable within the common housing chamber for treating the effluent stream, each combustion chamber module containing a foraminous sleeve defining a combustion chamber therewithin. In this way, multiple combustion chambers may be provided within a single, common housing, each of which may be configured to treat a particular effluent stream flow. Accordingly, the number of combustion chambers can be selected to match the different types and flowrates of the effluent stream expected from any particular processing tool. This provides an architecture which is readily scalable to suit the needs of different effluent gas stream types and flowrates while retaining a common housing which may interface with upstream and downstream components.

Title: Patterning parameter determination using a charged particle inspection system
Inventor: RUAN JUN-RU
IPC: H01J37/26
Filed: 2022-08-23
Abstract: A method of obtaining focus and dose data that requires no special marks and that uses images of in-die features is described. A focus/dose matrix wafer is created. Dimensions such as critical dimension (CD), CD uniformity (CDU), edge placement error (EPE), etc., at in-die locations are measured using a charged particle inspection system having a large field of view.

Granted: 1897-12-04
Abstract: 23,452. Lake, H. H., [Shaw, W.]. Oct. 12. Nailing.-Relates to a tack-driving machine in which the driver makes a number of strokes while the feeding-mechanism delivers one tack, so that time is allowed for the adjustment of the work between the driving of one tack and the delivery of another. The shaft B is driven by a belt on a pulley b, and actuates the driver in any usual way. The shaft D operating the feeding-mechanism carries a four-toothed ratchet-wheel d<3>, Fig. 3, which is engaged by a pair of pawls d<1>, d<2>, actuated by an eccentric b' on the shaft B. During a revolution of the shaft B the pawls d<1>, d<2> rotate the ratchet-wheel and shaft D through one-eighth of a revolution, the other eighth being accomplished by the gear described below. The shaft B drives, by means of a screw, a wheel b<3> carrying three cams b<4> which successively rock the lever j<6> and, by means of the rod j<5>, the lever j<2>. This lever j<2> is jointed to a sleeve k, Figs. 1 and 2, carrying a pawl j<1>. This pawl gears with a rack cut in the rod H, when the sleeve or shield J is withdrawn by means of a foot-lever G. The movements of the lever j<2> are thus conveyed to the rod H, which by means of a hook h operates the ratchet-wheel d<3>. The foot-lever G, when. depressed, pulls downwards a rod E, and by means of a hook e rotates the ratchet-wheel and shaft D so that a tack is immediately delivered through the shoot shown in dotted lines in Fig. 1.
