Semiconductor Processing Technicians

Semiconductor Processing Technicians typically perform the following tasks: • Manipulate valves, switches, and buttons, or key commands into control panels to start semiconductor processing cycles. • Maintain processing, production, and inspection information and reports. • Inspect materials, components, or products for surface defects and measure circuitry, using electronic test equipment, precision measuring instruments, microscope, and standard procedures. • Clean semiconductor wafers using cleaning equipment, such as chemical baths, automatic wafer cleaners, or blow-off wands. • Study work orders, instructions, formulas, and processing charts to determine specifications and sequence of operations. • Load and unload equipment chambers and transport finished product to storage or to area for further processing. • Clean and maintain equipment, including replacing etching and rinsing solutions and cleaning bath containers and work area. • Place semiconductor wafers in processing containers or equipment holders, using vacuum wand or tweezers. • Set, adjust, and readjust computerized or mechanical equipment controls to regulate power level, temperature, vacuum, and rotation speed of furnace, according to crystal growing specifications. • Etch, lap, polish, or grind wafers or ingots to form circuitry and change conductive properties, using etching, lapping, polishing, or grinding equipment. • Load semiconductor material into furnace. • Monitor operation and adjust controls of processing machines and equipment to produce compositions with specific electronic properties, using computer terminals. • Count, sort, and weigh processed items. • Calculate etching time based on thickness of material to be removed from wafers or crystals. • Inspect equipment for leaks, diagnose malfunctions, and request repairs. • Align photo mask pattern on photoresist layer, expose pattern to ultraviolet light, and develop pattern, using specialized equipment. • Stamp, etch, or scribe identifying information on finished component according to specifications. • Scribe or separate wafers into dice. • Connect reactor to computer, using hand tools and power tools. • Measure and weigh amounts of crystal growing materials, mix and grind materials, load materials into container, and monitor processing procedures to help identify crystal growing problems.
