TFM260 Thin Film Monitor

1 INTRODUCTION
Please read this manual carefully to ensure optimum operating conditions right from the start. This user manual handbook contains important information about the functionality, installation, start-up and operation of the Thin Film Monitor TFM260 .
1.1 INTENDED TO USE
TFM260 uses quartz crystal sensor technology to measure rate and thickness in a thin film deposition process. Two sensor inputs are standard and four additional sensor inputs are optional. Six recorder outputs provide both analog rate, thickness or frequency signals. Sensor inputs are assigned to different materials, averaged for accurate deposition control in large systems or configured for a dual sensor. The rate sampling mode allows a shuttered sensor to extend sensor life in high rate processes. Rate displays of 0.01 Å/s. In addition, frequency or mass displays can be selected. Four relay outputs allow TFM260 to control source or sensor shutters, signal time and thickness setpoints, and signal crystal failure. Digital inputs allow external signals to start/stop and zero readings. TFM260 comes with an RS-232 and Ethernet port. The implemented protocol is compatible with Inficon SQM-160 and you can use the same software to operate the TFM260 . The software can be used to set and store all parameters, operate TFM260 and save process data in a .txt file that can be imported into Excel.

It is possible to connect up to 3 modules depends on TFM260 hardware configuration and QMB6 interface kind. The device can support up to 6 channels at the same time. At the purchase stage, the number of internal channels of the device (2, 4 or 6 channels) is defined. In the case of the number of channels smaller than 6, it is possible to connect an external QMB6 module. Each external QMB6 module uses two measuring channel of the TFM260 . For example, a device equipped with 2 internal channels can be connected with a maximum of 2 (using 4 measuring channels) external modules.
The connection cable should be made in the standard 1 to 1. To make the cable, use a wire with a minimum wire diameter of 0.5mm2 see picture 3.6.
The configuration of the attached module is done from the user interface level, see section: 4.3.11

1. Sensor Item, 2. Tooling factor value for sensor,
· 100% tooling indicates that the sensor and substrate receive the same amount of material during deposition.
· Tooling values over 100% indicate that the sensor receives less material than the substrate (see section 8.1).
· Tooling values under 100% indicate that the sensor receives more material than the substrate (see section 8.1).
Tooling is set in the System menu. It adjusts the tooling for each individual sensor before it is averaged. Sensor Tooling for a sensor applies to all films. If the Sensor Tooling parameters are set properly, a sensor failure will not cause a jump in the average Rate and Thickness reading. The value can be set in the range from 10% to 400% Also check: “Film Tooling Factor” section 4.5.

4.3.4 MEASURMENT PERIOD
Sets the measurement interval between 0.1 second (10 readings per second) and 2 second. The parameter value is common to all internal measurement channels. For external channels(if available), the value can be set individually. A longer period gives higher reading accuracy, especially in low rate and low density applications. Time required for a measurement. Longer times yield higher accuracy.

4.3.5 CRYSTAL FREQUENCY MIN/MAX
Sensor Minimum and Maximum frequencies establish the operating range for the sensing quartz crystals. Both values are used to determine the % life that is displayed in Xtal Life mode. When the sensor frequency reads below the minimum or above the maximum, TFM260 indicates a sensor failure (crystal fail) with a red color Crystal Status indicator.

1. Sensor Item,
2. Crystal frequency minimum, if the value is smaller then the device displays the status “XTAL FAIL”,
3. Crystal frequency maxiumum, if the value is bigger then the device displays the status “XTAL FAIL”
Crystals sometimes fail unexpectedly, or exhibit erratic frequency shifts (mode hopping) before total failure. Depending on the material, crystals may fail well before the typical 5 MHz minimum. If the crystals consistently fail early, set FREQ MIN to a value higher than 5 MHz to provide a Crystal Life warning that is consistent with actual failure. A sensor crystal with an initial value that exceeds the maximum frequency will also cause a flashing Crystal Status indicator. The maximum frequency can be set slightly above the nominal values with no effect on accuracy.
TFM260 calculates the crystal life value based on the current frequency compared to the / values set in the System menu. A new crystal should indicate between 95 and 100% crystal life.
CAUTION

Crystal life status Usable crystal life depends on the material being evaporated and other process characteristics. Rate noise and other failure modes may be observed before the crystal life value reaches 0%.

4.3.6.1 RS232
RS-232 serial communications are accomplished through an industry standard 9-pin female connector found on the TFM260 rear panel (refer to 3.4.2). A mating male connector is required to attach a host interface. The host and TFM260 can be separated by up to 15 m using a multiconductor shielded data cable. For successful communications, the baud rate of the host computer and TFM260 must match. Available baud rate options are: 19200, 38400, 57600, and 115200 bps. NOTE: Unpredictable RS-232 hardware/software combinations may occasionally cause a command to not be recognized by TFM260 . Consequently, all communications should include an automatic retry procedure. If a command sent using RS-232 does not produce a response from TFM260 within three seconds, it should be sent again.
4.3.6.2 Ethernet
For Ethernet communications, TFM260 uses the static Internet Protocol (IP) (default address 192.168.0.100) The optional TCP/IP interface supports only the Standard Ethernet TCP/IP protocol. TFM260 will communicate using TCP/IP on TCP port number 2101. DHCP is also supported.
4.3.7 ANALOGUE OUTPUTS
TFM260 features analog outputs that will produce a 0 to 10 V (dc) representative of the current rate, thickness or frequency. Analogue outputs connectors are available on rear panel see section 3.4.4 You can assign any type of signal from any sensor to any analogue output. It is also possible to assign the same signal several times to several analogue outputs.

5 OPERATION – REMOTE CONTROL
TFM260 offers the following types of data communications hardware ports.
· Serial RS-232 port · Ethernet port
Both the host and server must have the same form of communications equipment and complementary setup. For serial communications, the baud rates and data word format must match. The word format for bit serial lines (RS-232) is comprised of ten signal bits: eight data bits, one start bit, one stop bit, and no parity. The eight data bits contain a byte of information or character whose ASCII value ranges from 0 to 255.
5.1 RS232 COMMUNICATION
RS-232 serial communications are accomplished through an industry standard 9-pin female connector found on the TFM260 rear panel (3.4.2). A mating male connector is required to attach a host interface. The host and TFM260 can be separated by up to 15.2 m (50 ft.) using multiconductor shielded data cable. For successful communications, the baud rate of the host and SQM-160 must match. Available baud rate options are: 2,400, 4,800, 9,600, 19,200, 38,400, 57,600, and 115,200 bps. TFM260 is configured as DCE (Data Communication Equipment).
CAUTION
Unpredictable RS-232 Unpredictable RS-232 hardware/software combinations may occasionally cause a command to not be recognized by TFM260 . Consequently, all communications should include an automatic retry procedure. If a command sent via RS-232 does not produce a response from TFM260 within three seconds, it should be sent again.
5.2 ETHERNET PORT
For Ethernet communications, TFM260 uses the static IP address 192.168.1.200. The optional Ethernet port supports only the Standard Ethernet TCP/IP protocol. TFM260 will communicate using TCP/IP on TCP port number 2101. The interface supports static and DHCP addressing. Ethernet parameters allow the IP address and the net mask to be set. A standard Ethernet cable is required to connect TFM260 through a network or hub connection.

5.3 COMMUNICATIONS PROTOCOL
TFM260 communicates with a host computer using an ASCII based protocol. TFM260 defaults to 19,200 baud, 8 data bits, and no parity. The baud rate can be changed in the TFM260 System menu, but is always 8 data bits with no parity.
