"Mask Making 101" * Tier 1 mask shops vs. Tier 2 mask shops: Is there a difference? * Ebeam vs. Laserwriters: What works best for your application? * Address units vs. spot size and grids * Data issues: not all GDS programs are the same o Dealing with conics o Fracturing of polygons * MEMS vs. electronics masks * DXF data vs. GDS data: Can you use both? * What drives mask costs * Defect inspection: How much do you really need or are you getting enough...

BSAC Seminar: FBAR Technology: Past, Present, and Future

February 20, 2008
Dr. Rich Ruby Avago February 20, 2008 | 12:00 to 01:00 | 521 Cory Hall, Hogan Room Host: John Huggins

This talk will be about thin film acoustic resonators. The resonator is manufactured on a 6 micron silicon substrate, and consists of a free-standing membrane 1 to 2 microns thick. This thin film is the acoustic stack. The stack has metal electrodes and a sputtered piezoelectric aluminum nitride film. Made in a CMOS fab in Fort Collins, we now ship over 1 million filters per day. This year, we will pass the one billion mark for shipped...

BSAC Seminar: When Applying Sonic Energy, One Size Does Not Fit All

Garry L. Montierth P.E. PCT Systems February 27, 2008 | 12:00 to 01:00 | 521 Cory Hall, Hogan Room Host: M. Wasilik

Sonic energy is being investigated to enhance processing in a many different technology areas including applications in such diverse fields as: - Chemical Synthesis new methods, green chemistry and catalysis - Electrochemistry analysis, plating, synthesis - Environmental Protection remediation of air, land and water - Food Technology drying, mixing and preservation - Materials Science - Extraction of raw materials from plants - Preparation of...

BSAC Seminar: Tools & Technologies for the Study of Protein Dynamics, Detection, and Interaction

April 2, 2008
Dr. Mekhail Anwar UCSF Medical School & MIT April 2, 2008 | 12:00 to 01:00 | 521 Cory Hall, Hogan Room Host: Ming Wu

The study of proteins in biological systems requires a comprehensive approach: investigating dynamics, interaction and identification.This talk will examine several technological approaches we have developed to address these needs, including an optics-free integrated circuit-based microarray imager compatible with existing (optics-based) microarray protocols. By eliminating optics, and developing the reader using integrated circuit technology, the...

BSAC Seminar: Piezoelectric Micromachined Ultrasonic Transducers

April 23, 2008
Dr. Hongsoo Choi Department of Mechanical & Aeronautical Engineering, UC Davis April 23, 2008 | 12:00 to 01:00 | 521 Cory Hall, Hogan Room Host: David Horsley & John Huggins

Experimental and numerical studies of Piezoelectric Micromachined Ultrasonic Transducers (pMUTs) were done to improve their performance. pMUT uses a micromachined multilayered membrane resonator as a sound radiating element and lead zirconate titanate (PZT) film in pMUT is mainly used as a component to drive the membranes. Thus pMUTs offer a more flexible and innovative approach to the...

BSAC Seminar: Microscope Manipulation of Cells and their Environment for Cell Sorting and Stem Cell Biology

May 7, 2008
Prof. Joel Voldman Department of Electrical Engineering and Computer Sciences, MIT May 7, 2008 | 12:00 to 01:00 | 521 Cory Hall, Hogan Room Host: Luke Lee

Microsystems have the potential to impact biology by providing new ways to manipulate cells and the microenvironment around them. These microsystems provide the interface between the macro world and the micro world of cells. Simply physically manipulating cells or their environment--using microfluidics, electric fields, or optical forces--provides new ways to separate cells and organize cell-cell interactions. The...

BSAC Seminar: Integrated MEMS Technologies for Adaptive Optics

May 14, 2008
Blake Lin Department of Electrical Engineering and Computer Sciences, UC Berkeley BSAC Graduate Student Researcher Dissertation Presentation May 14, 2008 | 12:00 to 01:00 | 521 Cory Hall, Hogan Room Host: Tsu-Jae King Liu & Richard Muller

Image resolutions of modern optical systems are many times limited by wavefront aberrations due to turbulence in the optical media. Adaptive Optics (AO) is a technology that utilizes a deformable mirror (DM) to correct the wavefront distortion, thereby enhancing the image resolution. In this thesis research, we...

BSAC Seminar: Elastic Guided Waves Divergence: Past and Present

May 23, 2008
Prof. Emeritus Morio Onoe University of Tokyo May 23, 2008 | 12:00 to 01:00 | 521 Cory Hall, Hogan Room Host: Clark Nguyen

Lord Rayleigh studied the first elastic guided wave known as Rayleigh surface wave in 1885 and similar guided waves in a plate known as Rayleigh-Lamb waves in 1888. They were pure mathematical analyses. He noted, however, these waves may play an important role in earthquakes due to its limited divergence in two dimensions. In fact early studies on guided waves were mainly conducted in seismology. A variety of engineering applications have emerged...
