Definitions
- This invention is m the field of semiconductor fabrication process monitoring and control, and methods therefor, and more par t icularly, s a device and method that applies to the calibration, monitoring and control of test equipment used on the process line to measure oxide charge including mobile ion contamination.
- Semiconductor wafers undergo a variety of measurements to measure and ensure the suitability of the wafer for further processing. Some of these measurements test for acceptable levels of charge time retention, dopant concentration, leakage and mobile ion concentration. In particular, one of these tests, for the detection of mobile ion concentration and other oxide charge is key to the successful fabrication of integrated circuits upon semiconductor wafers m the process line.
- the monitoring of mobile ion contaminants such as sodium ions or potassium ions is required to ensure that adequate yields result, and also to ensure that the reliability of the products is maintained at a quality level. Mobile ions are most commonly caused by the atoms of contaminant, or impure, materials. Two examples of iriaior sources of contaminants are sodium and potassium.
- Sodium may be introduced from quartz ware within oxide furnaces, and it may also be present in chemicals used during the semiconductor manufacturing process such as photoresist solutions. These contaminant ions are of course differentiated from implanted dopant ions such as boron and phosphorus .
- the first of these methods measures the capacitance-voltage (CV) of metal-oxide-silicon (MOS) structures.
- the second method measures surface photovoltage 'SPV) and oxide surface voltage (Vs't without using a metal contact, and in some cases measures tne amount of charge deposited on top of the oxide by a corona-dischar ⁇ e source.
- the first measurement method utilizes equipment that is categorized as a contact prooe tester to measure the CV.
- a contact probe tester method utilizes a process m which a voltage is incremented on a MOS electrode upon the surface of a semiconductor wafer using a contact prooe, and the corresponding increment in the charge upon the wafer, as measured by a contact probe coulombmeter is monitored.
- the second measurement method utilizes equipment that is categorized as a non-contact probe tester.
- a corona gun or wire is used to deposit charges on the dielectric for biasing it.
- An example of a non-contact probe tester is given m U.S. Pat. No. 5,498,974, and functions as follows: A wafer is charged with a non-contact corona discharge at a positive polarity until a positive dielectric field is developed. A negative, thougn equal m value, polarity is then applied to the wafer until a negative dielectric field is developed. The amount of corona discharge necessary to change the dielectric field from the positive field to the negative field is measured. This measured charge, Q m/ is noted.
- a further problem is that m order to control the oxide charge m a semiconductor fabrication line, it is necessary to distinguish between the variables associated with the dielectric layer of a wafer under test and the variables m the tester itself.
- An object of the present invention is to provide a system and method of producing improved calibration wafers.
- Another object of the present invention is to provide a system and method of producing calibration wafers having tne properties of predictability and stability m order to ensure the correct assessment of the production line equipment and the wafers m process .
- a further object cf the present invention s to provide a system and method of producing high quality calibration wafers capable of meetm ⁇ quaiitv control certification.
- An additional object cf the present invention is to provide a system and metr.o ⁇ of producing high quality calibration wafers tc enable distinguishing between the variables associated with the dielectric layer of a wafer under test and the variables in the tester itself.
- a stabilized wafer for monitoring and calibrating oxide charge test equipment comprises; a silicon wafer, a Si0 2 layer upon the silicon wafer, and a phosp osilicate glass layer formed in the Si0 2 layer for providing the stabilized wafer by stabilizing an Si0_ interface and containing oxygen ons.
- a method of constructing and using a stabilized wafer for monitoring and calibrating oxide charge test equipment comprises the steps of; providing a stabilized wafer for stabilizing an SiO : interface and containing oxygen ions, and using the stabilized wafer for monitoring and calibrating oxide charge test equipment.
- a method of constructing and using a stabilized wafer for monitoring and calibrating oxide charge test equipment comprises the steps of; providing a silicon wafer, placing a polarizable dielectric layer of Si0 2 or. the silicon wafer for stabilizing an SiO, interface and containing oxygen ions, forming a phospnosilicate glass layer m the top of the SiO_ layer, and anneali c. the silicon wafer.
- Fig. 1 is a scnematic drawing of tne device used to monitor and calibrate oxide cnarge testers according to the invention.
- Fig. 2 is a scnematic drawing of the device after polarization of tne PSG layer from an applied electric field and temperature- bias stressing.
- Fig. 3 is a scnematic drawing of the device after reversal of the temperature- ⁇ ias stressing of Figure 42 .
- Fig. 4 is an exemplary grapn of the change in surface potential of tne composite dielectric curing temperature-bias stressing.
- Fig. 5 is an exemplary grapn of the change m oxide charge parameters as a function of the PSG concentration.
- the present invention is applicable m the fields of both contact and non- contact probe testers and methods of testing for oxide charge, including mobile ion contamination. In a preferred embodiment, it is especially useful for the monitoring and calibration of non- contact probe testers such as the non-contact probe described m U.S. Pat. No, ⁇ ,498,9 "7 4.
- a wafer standard cf the present invention is constructed from a silicon wafer with a silicon dioxide (SiO,) layer and a layer of phospnosilicate glass (PSG) , and is used for the monitoring and calioration of the mobile ion contact and non-contact probe testers.
- the polarization properties of tne PSG simulate mobile ions m the SiO by causing a shift m the surface potential of the SiO dielectric after temperature and bias are applied. This phenomena is stable and repeatable making it ideal for mobile ion proce tester calibration and monitoring.
- Mobile ion prooe tester calibrators m the form of wafer standards are desiraD e but difficult to Puiid Because dielectrics that nave been purposely contaminated witn modiie ions tend to de unpredictable and unstable.
- the use of a pnospnosilicate (PSG) qlass layer solves this prodlem because its polarization properties result in desirable qualities cf such as the charge drift that has been placed in the wafer is reversible from one polarity to the opposite polarity. Additionally, the wafer charge drift will saturate at a certain level, and then maintain at that level, for a given stressing electric field, time and temperature.
- PSG pnospnosilicate
- the wafer's PSG layer has the effect of passivating the Si0 2 , thus preventing the Si-Si0 2 , interface charge cf the grown oxide from shifting and thereby locks in the overall charge characteristics of the final SiO,/PSG composite dielectric. Therefore, the PSG wafer of the present invention has desirable properties of repeatability and stability.
- PSG film compositions in SiO can be formed by a number of processes.
- An exemplary method of producing PSG film compositions in SiO is by alloying thermally grown SiO, with phosphorus pentoxide (P 2 0 5 ) vapor followed by a nitrogen anneal.
- the P 2 0 5 vapor may be from either, a solid P 2 0. : source, a liquid POC1, source, a spin-on-giass phosphorus source, cr a phosphorus doped OVD-SiO, source .
- Another exemplary method of producing PSG film compositions in SiO is by ion implantation of phosphorus followed by an oxygen anneal .
- the wafer standard of the present invention is suitable for both contact and non-contact probe testers. If the desired use of the wafer standard is with a contact probe tester, a further addition to a preferred embodiment may be the addition cf a MOS structure.
- a MOS structure s formed by processing metal contacts on top of the composite dielectric. Additionally, some contact probe testers are designed to measure dielectric properties of wafers without the need of metal contacts, and these contact probe testers may be used with the wafer standard that either do, or do not, have MOS structure metal contacts. If the present invention is desired to oe used with non- contact probe testers, a corona gun or wire is used to deposit a charge upon the wafer standard in a controlled fashion.
- the applicable measurements of the properties of the wafer standard device formed by the composite dielectric and silicon wafer are obtained by simply using the non-contact probe tester to determine the SPV, Vs and corona charge deposited on top of the dielectric.
- An Additional advantage and feature of the wafer standard of the present invention in a preferred embodiment includes that since the PSG stabilizes all charges m the Si0 2/ the measurement of leakage, threshold voltage (Vt) , equivalent charge (Qeff) , total charge (Qtot) , density of interface traps (Dit) , density of oxide traps (Dot), flatband voltage (Vfb), dielectric thickness (Tox)and surface photovoltage (SPV) becomes repeatable day m and day out over months of time. Additionally, the wafer standard becomes the means to measure and control the variables m a probe tester including the variables having their origins in electrical, mechanical, thermal or computer software components. Furthermore, a wafer standard, m a preferred embodiment of the present invention, may be used to monitor, calibrate and troubieshoot oxide charge testers and correlate it with other testers.
- the wafer standard device 10 for calibrating mobile ion probe testers, or oxide charge testers is shown.
- the wafer standard device 10 in a preferred embodiment, is a silicon wafer 16 with a pola ⁇ zable dielectric layer.
- the dielectric may be Si0 2 14 with a PSG 12 layer en the top.
- the SiO, 14 is thermally grown to a thickness of approximately 500 to 700 angstroms and the PSG 12 is formed by either diffusing or ion implanting pnospnorus into tne SiO, 14.
- special cases ignt use SiO, 14 thermally grown to a th ⁇ c ⁇ ness as thin as about 100 angstroms and as thick as about 1500 angstroms.
- An appropriate anneal is done to complete the wafer standard device 10.
- the anneal must minimize S ⁇ -S ⁇ O ⁇ interface charge and assure the formation of the P O. molecule.
- an oxygen anneal between about 700°C to about 1000°C is used to incorporate oxygen into the process so that P 0.. is formed, though m a preferred embodiment, a temperature range of about 900°C to about 1000°C is used for the oxygen anneal.
- a nitrogen anneal m the same temperature range (s) as that used for the oxygen anneal is sufficient because the oxygen is available to form P,0 5 during the POCL3 deposition.
- PSG 12 is thus formed by alloying SiO 14 with P,0..
- the PSG 12 serves to ensure that movement of ions such as oxygen are contained within the PSG 12. Furthermore, the PSG 12 protects and stabilizes the SiO, 14 interface.
- the structure of the S ⁇ 0 2 14 is composed of interconnected tetrahedra of S ⁇ 0 4 . Alloying Si0 2 14 with P 2 0 5 to form PSG 12 incorporates tetrahedra of PO justify into the network of S ⁇ 0 2 14.
- the non-bridgmg oxygen ion associated with every other phosphorus ion results m a loosely bound oxygen ion that transfers between neighboring PO filed tetrahedra under the influence of an applied electric field.
- the mobility of the oxygen ion results m the electrical polarization of tne PSG 12.
- the mooile ions stay inside the PSG 12 layer.
- the negative oxygen ions also act to getter oxide contaminates such as mobile positive ions like sodium that weaken and destabilize the SiO, 14.
- This beneficial effect of the PSG 12 layer accounts for the repeatability of the mobile ion measurement day m day out over months of testing. Furthermore, the PSG 12 formation general... , coincides .-vitn a quidus cnase.
- the resulting continuous qiass ⁇ ayer over the oxioe accounts for an increase m the dielectric strength of the PSG/SiO, composite compared to SiO, alone and greatly reduces flaw-type failures.
- Another beneficial effect of the continuous glass layer formed by tne PSG 12 is to stabilize the overa-1 cnarge characteristics of the capacitor formed by the S1-S1O -PSG, assuring the repeatability of interface and ouik charge measurements such as: leakage, Vt, Vfb, Qeff, Tox, Dit, Dot, Qtot, spv tests etc.
- the result is a wafer standard device 10 ideal for use as a wafer standard for oxioe charge testers .
- the dipoies of the PSG 12 may be randomly disordered m some initial state.
- the dipoies snou ⁇ o be pre-aligned at tne beginning of tne calibration metnoc to bring them to an orderly initial state. This can oe accomplished by letting the dipoies come to equilibrium at room temperature Pefore testing of oxide testers or by defining some other initial state by pre-aligning tne dipoies m the PSG 12 layer.
- the method for calibrating the wafer standard device 10 begins by aligning the dipoies of the polarization layer, PSG 12, in the same direction.
- tms is best accomplished by thermal stressing using a negative corona Pias for p-type wafers and positive corona Dias for n-type wafers.
- the normal mobile ion test routine _s carried out which usually consists of a "pusn” using positive bias followed by multiple "pulls" using negative bias (see Fig. # 3) to get full oipole reversal and a consistent mobile ion measurement.
- the present embodiment shows the use of plus and minus 8 .ilovolts for this procedure of pusn v F ⁇ g. 2) and pull (Fig. 3 .
- the actual voltage used for this procedure may vary however _-. accordance with the equipment or platform that tne wafer standard device 10 of the present _nvent ⁇ cn is being used with.
- a typical PSG composition, temperature- bias stress condition and related surface voltage shift as a function of time are shown.
- the PSG concentration m the SiO is between one and fifteen mole percent.
- the concentration of PSG is controlled by the time, temperature and parts per million (ppm) of the ? 0 5 diffusion. For ion implantation, it is the dose and energy of tne pnosphorus ion implantation that sets the concentration.
- the final concentration cf the PSG is measured by Secondary Ion Mass Spectroscopy 'SIMS), or by the etch rate of the PSG m a dilute HF bath.
- Thermal stress conditions may vary by species of dipoies and type of dielectric.
- Typical stress temperatures for PSG m S ⁇ 0 2 range from 170°C to 280°C and typical biasing electric fields vary from 0.5 x 10 volts per centimeter to 2.5 x 10' volts per centimeter. This combination of thermal stress conditions gives a flatband voltage shift of between 30 millivolts and 250 millivolts for a dielectric thickness from 500 angstroms to 1000 angstroms. This corresponds to mobile ion concentrations of from 0.5 x 10 10 ions per square centimeter to 20 x 10 10 ions per square centimeter.
- Figure # 5 shows the change m various oxide charges as the concentration of PSG changes.
- the wafer standard device 10 (Fig. 1-3) can be fabricated to give the end user the quantity of charge desired for a particular application.
- Q n/ for example, if 4xlO iC mobile ions per square centimeter are oesired, the PSG concentration would be 5 mole %.
- Qeff of 4x10-- charges per square centimeter the PSG concentration would be 2 moIe % .
