Description
This HF Vapor Dry Etch system is configured with Hydrofluoric and Ethanol vapor used, primarily, for isotropic etching of silicon dioxide without a plasma. The HFVapor system etches at reduced pressure and 45C to isotropically etch sacrificial silicon oxide layers, primarily to release silicon microstructures in MEMS devices. The dry process avoids stiction of released moving parts and damage to delicate structures – common issues with conventional wet processing technology. This is a single wafer system for 4 inch to 8 inch wafers and dies on a carrier wafer.
Details
Etch target is primarily silicon dioxide. Recommended mask materials are silicon, Al, Au, Cr, Ni, SiC, Al2O3, LPCVD nitride. PECVD nitride is NOT recommended as a masking material.

| UW Academic Rate: | $77/hr | |
| Industrial Rate: | $231/hr | |
| Outside Academic Rate: | $77/hr | |
Description
The XeF2 vapor etch tool is for primarily for isotropic chemical etching of silicon sacrificial layers for the release of MEMS structures.
Details
Xenon difluoride (XeF2) provides a highly selective isotropic etch for Si, Mo and Ge and is an ideal solution for etching sacrificial layers to “release” moving components within MEMS devices. It provides numerous unique advantages and capabilities compared to wet and SF6 plasma etch options. The process is generally carried out at pressures between 0.5 and 4 torr providing controlled, stiction-free and residue-free etching. Typical vertical and lateral silicon etch rates are in the 0.1 - 10 microns/minute range. Because of its selectivity and excellent reach, XeF2 can be used to make very long undercuts with little or no degradation of etch stop, mask or device layers. Silicon dioxide masks, with a Si:oxide selectivity of >1,000:1, have been used to achieve very long undercuts (well over 100μm) and to protect extremely small or thin devices (less than 30nm). XeF2 does not attack polymers or other organic films. Photoresist can be used as a cost-effective mask and polymeric passivation layers, such as those from the Bosch Process, can be used as an effective protective layer for trench sidewalls. XeF2 is also an ideal way to release PDMS, parylene, and SU8. Since XeF2 does not etch packing and dicing materials, it can increase yield by delaying the release of a MEMS device until after dicing or package insertion and wire bonding. XeF2 has been used successfully to release MEMS devices on diced wafers and chips inside packages.
Materials Restrictions
Allowed etch target materials: silicon, germanium, molybdenum, SiGe, Ti, W. Allowed masks(typical selectivity): photo/ebeam resists, PDMS, silicon dioxide(1000:1), silicon nitride(100:1), Au, Al, Ni, Cr, Pt, SiC. DO NOT use this tool for thinning silicon wafers or to thin silicon chips. See tool owner for further information.

Description
EVAP1 is an electron beam evaporator for depositing metal films. It is cryopumped with a base pressure less than 2x10-6 Torr. The system holds 4 crucibles of metal, thus up to 4 metals can be subsequently deposited.
Details
The system has a capacity up to nine 100mm wafers in a planetary holder. Smaller pieces can be held by inserts. Typical evaporation sources are Ti, Au, Cr, Pt, Ag, Al, Pd, Cu, and Ni. Other sources are available. Precious metals (Au, Pt, and Pd) are charged by use. Users are welcome to request new materials and need to work with staff on developing proper recipes. The distance from the evaporation source to the wafer holder is about 19.5 inches.
Serial Number: 11199
Gold, palladium, and platinum must be checked out in Coral weighed before and after use. A scale for this is available next to the checkout cabinet. Make sure the gold crucible is placed on two carbon disks. The platinum crucible must make very good thermal contact with the hearth to avoid melting. Make sure the crucible fits all the way into the hearth with the top of the crucible flush with the hearth, and that the hearth is very clean before it is loaded.
Materials Restrictions
Only pure metals are recommended. The evaporation process typically does not allow for effective deposition of compound materials. Photoresist-coated substrates are allowed. Inorganic substrates are allowed in the system. Organic substrates may be allowed with staff permission.

Description
The E-beam Evaporator is a metal evaporation system that uses an electron beam to heat the metal sources. The system has 6 pockets for different materials during deposition.
Pocket #1 is titanium, pocket #2 is chrome, Pocket #3 is gold, pocket #4 is platinum, pocked #5 is palladium or copper, and pocket #6 is aluminum.
The materials are put into crucible liners for better heat uniformity throughout the source material and to allow for easy removal and refilling. The vacuum system is produced via a cryopump as the high vacuum pump. There is a mechanical pump that is capable of roughing the chamber and regenerating the cryopump as needed.
Details
This system has a capacity of up to seven 100mm wafers when using the liftoff fixturing and fifteen 100mm wafers when using the planetary. It can also hold 3 200mm wafers in a planetary configuration. Holders for smaller pieces are also available. This system is the most automated of our evaporation systems and is capable of producing multilayer stacks without user intervention. Precious metals (Au, Pd, and Pt) are charged by use. This system also includes a heater so that depositions can be performed at up to 300 C and an ion mill to clean surfaces prior to deposition. The distance from the evaporation source to the wafer holder is about 14.5 inches.
System #6629 Solution
Make sure the gold crucible is placed on two carbon disks. The platinum crucible must make very good thermal contact with the hearth to avoid melting. Make sure the crucible fits all the way into the hearth with the top of the crucible flush with the hearth, and that the hearth is very clean before it is loaded.
Materials Restrictions
Most substrates are allowed. Consult a staff member prior to new processes on substrates other than glass, quartz, or silicon. Only pure metals are recommended. The evaporation process typically does not allow for effective deposition of compound materials. Photoresist is typically allowed, but ask a staff member prior to performing a new process.

Description
This cryo pumped system is used for sputter deposition of films, with DC, RF, and pulsed DC power supplies. Targets materials include: Al, Ti, Au, Ti/W, Ni, ZnO, ITO, Nb, Cr, Cu, Ir, and Ni/Cr.
Details
Three sample holders are available for the system. There are holders for both 150mm and 4 inch wafers, plus a reconfigurable small-parts holder. Small parts must be of similar thickness to a wafer. Additional holders for specific samples can be fabricated.
The system has four power supplies. Power supply 1 (1500W max, DC) can be connected to guns 1, 2, 3, and 4. Power supply 4 (600W max, RF) can be connected to all five guns. Power supply 5 (1500W max, DC/pulsed DC) connects only to gun 5. Power supply 6 (100W max, RF) is used to bias the substrate. Only one power supply can connected to each gun at one time. Up to three guns can be sputtering at the same time if the guns are chosen carefully e.g. Gun 1 (DC), Gun 3 (RF), Gun 5 (DC) could be used for cosputtering.
Radio frequency (RF) supplies are used to counteract charge buildup that occurs on nonconducting targets. This is required for most oxides and nitrides used in the system. Conductive samples can be sputtered using an RF supply, but tend to sputter more slowly than with DC supplies.
Materials Restrictions
Organic substrates require staff review and permission prior to use. Photoresists are allowed in the system. Target placement must be reserved in advance by contacting darick@uw.edu. The target schedule is available here: http://goo.gl/fd0Gbh

Description
Low temperature (125C) and high temperature (350C), high-rate PECVD of SiO, SiN, and amorphous-Si on up to 200mm substrates with dual frequency supplies for stress tuning.
Details
This system runs automated depositions by first conditioning the chamber, then running the deposition, and then cleaning. This makes the deposited films very repeatable and minimizes the need for systems shutdowns to clean the chamber.
Materials Restrictions
Because the system runs at high temperatures it is imperative that samples be compatible with those temperatures. Prior to deposition on low temperature materials or plastics, consult with staff.
