A computer program product, comprising a computer readable storage device having a computer readable program code stored therein, said program code including an algorithm adapted to be executed by a computer to implement a method. First, design information of a design structure is provided including a back-end-of-line layer of an integrated circuit which includes N interconnect layers, wherein N is a positive integer. Next, each interconnect layer is divided into multiple pixels. Next, a first path of a traveling particle in a first interconnect layer of the N interconnect layers is determined. Next, M path pixels of the multiple pixels of the first interconnect layer on the first path of the traveling particle are identified, wherein M is a positive integer. Next, a first loss energy lost by the traveling particle due to its completely passing through a first pixel of the M path pixels is determined.

Computer program products for determining stopping powers of design structures with respect to a traveling particle

A system, a method and a computer program product for analyzing a circuit design provide for discretizing the circuit design into a series of pixels. A fraction of at least one constituent material is determined for each pixel. A deflection is also determined for each pixel. The deflection is predicated upon a planarizing of the pixel, and it is calculated while utilizing an algorithm that includes the fraction of the at least one constituent material. A series of deflections for the series of pixels may be mapped and evaluated.

Deflection analysis system and method for circuit design

A method of determining a stopping power of a design structure with respect to a traveling particle. The method includes (i) providing design information of the design structure comprising a back-end-of-line layer which includes N interconnect layers, N being a positive integer, (ii) dividing each interconnect layer of the N interconnect layers into multiple pixels, and (iii) determining a first path of the traveling particle in a first interconnect layer of the N interconnect layers, (iv) identifying M path pixels of the multiple pixels of the first interconnect layer on the first path of the traveling particle, M being a positive integer, and (v) determining a first loss energy lost by the traveling particle due to its completely passing through a first pixel of the M path pixels.

Method of determining stopping powers of design structures with respect to a traveling particle

A method for analyzing circuit designs includes discretizing a design representation into pixel elements representative of a structure in the design and determining at least one property for each pixel element representing a portion of the design. Then, a response of the design is determined due to local properties across the design.

Method of extracting properties of back end of line (BEOL) chip architecture

A thick-oxide ESD transistor for a BiCMOS integrated circuit has its source/drain contacts formed of the BiCMOS base or emitter polysilicon and its source/drain formed by an outdiffusion of the respective polysilicon contact. In one embodiment the BiCMOS resistor doping deepens the ESD source/drains, and in another embodiment the BiCMOS collector reach through doping deepens the ESD source/drains. The entire ESD transistor is fabricated from a standard BiCMOS process without any additional steps, has an area of about 100 square microns, can shunt up to 6000 volts, and has a turn-on time of about 10 picoseconds.
