A high performance 0.20 /spl mu/m logic technology has been developed with six levels of planarized copper interconnects. 0.15 transistors (L/sub gate/=0.15/spl plusmn/0.04 mu/m) are optimized for 1.8 V operation to provide low power-delay products and excellent reliability. Copper integrated into the back-end resistance Critical layer pitches summarized enable fabrication 7.6 mu/m/sup 2/ 6T SRAM cells.
The Linac for Image Guided Hadron Therapy (LIGHT) system has been developed as the first commercial high-frequency linac-based proton therapy accelerator system. As part of development process and technical validation concept, a reduced energy prototype linac (including all key functional aspects full accelerator) designed tested in parallel with preparation work full-scale LIGHT construction, installation, commissioning beam allowed identification gaps design improvements before transfer to...
On-line verification of the delivered dose during proton and carbon ion radiotherapy is currently a very desirable goal for quality assurance hadron therapy treatment plans. In-beam positron emission tomography (ibPET), which can provide an image β+ activity induced in patient irradiation, turn correlated to range beam, one modalities achieving this goal. Application requires that scanner geometry be modified from used nuclear medicine. In particular, PET detectors allow sub-nanosecond...
A prototype 10×10 cm active-area proton range telescope (PRT) has been built for use in quality assurance hadrontherapy. The PRT uses two triple-GEM detectors tracking and a stack of 3 mm-thick plastic scintillators the residual determination. tested with beams at Paul Scherrer Institut (PSI) Villigen, Switzerland. Presentation results will be followed by discussion plans to build larger having 30 cm×30 active area.
A portable electronics solution for gaseous detector readout is being developed use in high-rate tracking experiments or medical imaging applications. The frontend makes of the IDEAS VATA family 128-channel charge-sensitive ICs coupled with pitch-adaptor diode-protection circuit originally designed CERN TOTEM experiment. Each input channel front-end can be programmed individual trigger and a global threshold DAC adjustment used to achieve uniform over all channels. Chip programming...
Daily verification of the proton beam range in radiation therapy is a vital part quality assurance (QA) program. The objective this work to study use multilayer Faraday cup (MLFC) perform quick and precise daily beams produced by synchrotron.Proton depth dose measurements were performed at room iso-center water using PTW tank Bragg Peak ion chamber. IBA Giraffe, calibrated against data, was used measure equivalent thickness (WET) sample copper plates. WET provided calibration factors for...
Particle therapy is a highly conformal radiotherapy technique which reduces the dose deposited to surrounding normal tissues.In order fully exploit its advantages, treatment monitoring necessary minimize uncertainties related delivery.Up now, only clinically feasible for of therapeutic irradiation with particle beams Positron Emission Tomography (PET).In this work we have compared Resistive Plate Chamber (RPC)-based PET scanner scintillation-crystal-based application.In general, main...
In this work a 3.97 /spl mu/m/sup 2/ 6T CMOS SRAM bitcell technology has been developed using logic based platform incorporating self-aligned local interconnect and copper metallization. This 0.20 mu/m process is suitable for stand-alone applications as well embedded such digital signal processors. A stable operation demonstrated power supply (Vdd) of 1.8 V. technology, the minimum transistor (0.27 mu/m/spl times/0.15 mu/m) with gate pitch 0.54 metal 0.65 mu/m.
The ChemicalVia process, patented by CERN, provides a new method of making microvias in high‐density multilayer printed circuit boards different types, such as sequential build‐up (SBU), high density interconnected (HDI), or laminated multi‐chip modules (MCM‐L). process uses chemical etching instead laser, plasma other techniques and can be implemented chain production line. This results an overall reduced operation maintenance cost much shorter hole time compared with microvia processes.
Positron emission tomography (PET) is one of the most promising techniques for hadron therapy monitoring. This method uses imaging annihilation photons resulting from positron emitting isotopes produced during patient irradiation in therapy. In order to maximize sensitivity, in-beam PET preferred option, which requires a partial ring configuration. The usage systems causes image artefacts and low quality images due incomplete data. inclusion Time-of-flight (TO F) information into...
With finer geometries and multiple metal levels, CMP planarity demands have increased at the lower device levels. Interconnect material changes (metals such as W, Ti, TiN dielectrics BP-TEOS, HDP, F-HDP) process (such pads tool sets) were explored to improve post-polish local interconnect level. The pad hardness was found offer best avenue, with up a tenfold decrease in post-CMP interlevel dielectric thickness range.
A high performance sub-0.25 /spl mu/m CMOS technology has been developed with six levels of planarized copper interconnects. 0.15 transistors (L/sub gate/=0.15 mu/m) are optimized for 1.8 V operation to provide low power-delay products and excellent reliability. Copper integrated into the back-end resistance interconnects minimize wiring induced RC delays.
