Film Stress and Wafer Bow Measurement Systems. ( Room Temperature and High Temperatures - for Si or GaAs applications).
We pioneered the optical lever (optilever) laser scanning technique for measuring film stress and wafer bow. Over 400 systems are installed worldwide. Our system is used routinely by fabs to monitor the film deposition process, which if not controlled, could lead to delamination, cracking and void formation in the wafer.

2.Integrated Metrology Annealing Chamber ( Rapid characterization of new materials like Copper, low k dielectric and novel films ).
The FSM 900TC-vac is based on a vacuum RTP type chamber with multiple metrology to simultaneously measure Stress hysteresis, Thermal Desorption Spectroscopy (TDS), Film Shrinkage and Reflectivity changes during a heat cycle. These information provide a rapid means to gauge the thermal stability and the suitability of a new materials and processes before releasing them to production. Most advanced fabs involved in low k, Cu development and MEMs technology have the FSM 900TC-vac tool. System may also incorporate an in situ 4 Point probe to study Resistivity changes of a material during a thermal cycle. Chamber operates up to 900 degrees C . A 1100 degrees C version is optionally available.
3.Thin film Quantitative Adhesion Testers.
We offer the tools based on the 2 methods widely adopted by the microelectronic industry for film adhesion testing- that is, the 4 Point Bend technique and MELT ( modified edge lift off test). Systems are available to test samples in ambient or in solutions.
4.Substrate Thickness Measurement Systems ( Ultra thin Si or GaAs wafers - after Backgrind .
and Chemical Etching).
The FSM 413 proprietary optics is designed to measure wafer substrate thickness and TTV ( total thickness variation ) of ultra-thin wafers- even if these are supported by carriers like tapes, sapphire or quartz. Tool may also be used to profile depth of etched vias and trenches in MEMs and Optoelectronic devices.
The Indus Valley civilization was founded around 2,500 B.C. in the western part of South Asia, in what today is Pakistan and western India. It is often referred to as Harappan Civilization after its first discovered city, Harappa. It existed for about 1,000 years. The earliest traces of civilization...
They are built on a silicon wafers. ... Wafers with diameter doubled that one used in the University and they are an epitaxial-layered wafers. ... The wafer is etched to clean the surface. ... The wafer is soft baked at 90c for 45 seconds. ... The wafers are placed back into the furnace. ...
During manufacturer, a wafer may contain several hundred devices. Each individual device on a wafer is called a die. 3. ... Wafers are then cleaned with chemical solutions to remove organic impurities and particles from the wafer surface. ... Each finished wafer may contain several hundred actual devices or die. ... After probe test, the wafer is scored and broken into individual die. ...
Every Thanksgiving my family makes a delicious banana pudding for dessert. For you to make the banana pudding you need the right equipment and ingredients. You will need a double boiler, with the water in the lower pot. Before you can start combining the ingredients; you need to separate two eggs w...
DUL is the current form of getting light to carve circuit patterns onto the wafers of silicon which then become silicon chips, or more commonly know as processors. The problem here is though there is only a certain number of transistors that you can stick onto a wafer. ... The current method, DUL, is like photography in the way that it transfers resistors onto the wafer. The photo it takes is taken and then transferred to the "film" in this case the wafer. The main part in making a processor faster is to add more transistors to the wafer using through a lights wave length. ...
He takes a substrate wafer of Gallium Arsenide and in a chamber there are connected MBE heads which are controlled to emit different elements. ... In figure 6) we have reached the point where the wafer is at the point for an infusion of electrons. ... On each of these wafers the quantum dots are in between the substrate. ... If the quantum dots are placed in the cavity, the spot on the wafers where there are no crystals, in the middle, and capture electrons then the aims of the process are a success. ...
