Information boxBolt-on data acquisition unit for probers

The information box is bolted onto an installed prober, reads wafer geometry and test counts, and sends them to a 4-page board.

One link to the machine, one to the plant network

The information box reads data from the machine's configuration card and running memory and mirrors the machine screen read-only. A second link goes to the plant network and the production board; each hop to EAP / MES is marked with its own status.

Board screens

The 4 pages of one system. The four boards on the wall of the CP hall use these live screens.

Screenshot of the run overview page from a live machine: cards for LOT, wafer progress, yield and box health, with the UF200 live screen on the right
Run overviewLOT / WAFER / DEVICE, wafer progress, BIN distribution and box health on one screen. The UF200 live screen is synchronised on the right, and any number that could not be read shows --.
Screenshot of the UF200 live screen from a live machine: the machine's native screen, showing fields such as DEVICE, WAFER SIZE, INDEX X/Y, YIELD and LOT
UF200 live screenThe machine's native screen is mirrored read-only to the web page and the board. Alarm lines the machine raises itself are shown as they are, unaltered.
Screenshot of the external wafer map from a live machine: the full die map in the middle, recipe, run and BIN counts in the left column, and link states in the right column
External wafer mapRebuilds the full die map from index X/Y and grid size, with each link's state listed in the right column. A link that is not connected reads NOT CONNECTED.
Screenshot of the SECS/GEM and EAP interface page from a live machine: communication topology of EAP / MES, HSMS, GEM and UF200, with each hop's status marked
SECS/GEM · EAP interfaceExternal Host configuration and the current session state are shown separately. On the protocol topology each hop is marked on its own: evidence present, to be inferred, blocked or faulty.

Screens are screenshots from a live machine, with internal identifiers (addresses, device numbers, internal component names) masked.

Applications

Data for legacy tools

Gives in-service probers without modern data interfaces a readable set of run facts. Output, machine state and alarms go straight to the board and the plant network, so connecting a machine does not mean replacing it.

Probe-card usage history

Reads cumulative touchdown and cleaning counts to support card change and cleaning decisions. Values are decoded losslessly, parameter by parameter, from the machine's raw parameters.

Remote status view

Watch the machine screen and run counters from the plant network instead of walking to the tool. What is seen in the office is the same screen as at the machine.

Checks before EAP connection

Check the machine's native GEM / HSMS program, data dictionary and run logs directly. Each hop from EAP / MES to the machine is marked with its own status, so wrong connections show up before go-live.

In development, confirmed machine by machine on site

The information box is in development, and the board screens are screenshots from a live machine. What can be read depends on the machine model and interfaces, and is confirmed by surveying each machine.

Every page states the grade of its data source, and a page whose source is not connected locks itself automatically. Inferred values never stand in for measured ones, and no compliance certification or factory-system reporting on the machine's behalf is claimed.

From survey to delivery definition

  1. Machine and interface surveyConfirm the model, the usable interfaces and the plant network conditions.
  2. Source validationVerify the configuration card, run counters and barcode paths one by one.
  3. On-site trialObserve data and stability at real production rhythm.
  4. Delivery definitionSet acquisition scope, deployment form and support from the validation results.
