Abstract:
A Wafer Image Modeling and Prediction System (“WIMAPS”) is described that includes systems and methods that generate and/or apply models of resolution enhancement techniques (“RET”) and printing processes in integrated circuit (“IC”) fabrication. The WIMAPS provides efficient processes for use by designers in predicting the RET and wafer printing process so as to allow designers to filter predict printed silicon contours prior to application of RET and printing processes to the circuit design
Abstract:
Systems and methods for timing-driven shape closure in integrated circuit (“IC”) fabrication are provided. These Integrated Design-Manufacturing Processes (“IDMP”) include a delta flow that integrates information of the IC fabrication timing and geometry verification processes into the IC design. The delta flow is an incremental flow that includes delta-geometry timing prediction processes and/or delta-timing shape prediction processes for processing difference information associated with circuit characterization parameters. The delta flow independently re-characterizes an IC design using the difference or delta information corresponding to the circuit characterization parameters. The delta flow provides delta outputs (incremental) that enhance or re-characterize corresponding parameters of the devices and interconnect structures without the need to generate new circuit characterization parameters and without the need to re-process all information of the IC design.
Abstract:
A method and apparatus for creating a phase shifting mask and a structure mask for shrinking integrated circuit designs. One embodiment of the invention includes using a two mask process. The first mask is a phase shift mask and the second mask is a single phase structure mask. The phase shift mask primarily defines regions requiring phase shifting. The single phase structure mask primarily defines regions not requiring phase shifting. The single phase structure mask also prevents the erasure of the phase shifting regions and prevents the creation of undesirable artifact regions that would otherwise be created by the phase shift mask. Both masks are derived from a set of masks used in a larger minimum dimension process technology.

Abstract:
A subscriber identity model (SIM) card holder for fixing and connecting a SIM card with a circuit board is disclosed. The SIM card holder comprises a tray, a terminal rack, and electrically conductive terminals. A bottom surface of the tray defines a first card slot. A bottom surface of the first card slot defines a second card slot. The second slot penetrates the first card slot as well as a top surface of the tray. When the SIM card is contained in the first card slot and/or a micro-SIM card is contained in the second card slot, metal contacting parts of the SIM card are positioned directly under metal contacting parts of the micro-SIM card. The SIM card holder of the present invention is capable of containing the SIM card and the micro-SIM card.
Abstract:
An electrical connector includes a first insulating body having a base board and a first tongue board extending rearward from a bottom of the base board, first terminals each having a first contact portion disposed on the base board, a second insulating body having a base portion and a second tongue board extending forward from a bottom of the base portion, and second terminals each having a second contact portion stretching out of a front of the base portion and disposed above the second tongue board. Two opposite sides of the first tongue board protrude upward to form two clipping walls defining a receiving space therebetween. The second insulating body is received in the receiving space of the first insulating body with the base portion being clipped between the clipping walls and a front end of the second tongue board abutting against a rear end of the base board.
Abstract:
An electrical connector includes a first insulating body having a base board and a tongue board extending rearward from the base board, and a second insulating body having a base portion and fingers extending forward from the base portion. Two opposite sides of the tongue board protrude upward to form two clipping walls and oppositely protrude outward to form two restraining portions spaced from the clipping walls. A receiving space is formed among the tongue board, the base board and the clipping walls for receiving the second insulating body therein. The base portion is clipped between the clipping walls. Front ends of the fingers prop against the base board. Each side surface of the base portion defines an elastic arm having a top connected with the side surface and a bottom beyond a bottom surface of the base portion to be restrained between the restraining portion and the clipping wall.
Abstract:
An audio jack connector adapted for receiving a plug has a base which has a socket, a first terminal groove and a second terminal groove opened at a same side of the socket. The second terminal groove is located between the socket and the first terminal groove and connects with the socket through a first connecting passage. A stationary switch terminal has a first fixing slice fastened in the first terminal groove and a first contacting end projected in the first connecting passage. A resilient switch terminal has a second fixing slice fastened in the second terminal groove, a second contacting end contacting the first contacting end and projected into the socket through the first connecting passage and an opening opened in the second fixing slice for receiving the second contacting end when the second contacting end is biased by the plug to be disconnected from the first contacting end.
