What Sitek Process Solutions does

Sitek Process Solutions Inc. is a privately held semiconductor equipment company headquartered in Rocklin, California, founded in 1997 with 11-50 employees. The company specializes in the manufacture, refurbishment, and aftermarket support of Spin Rinse Dryers (SRDs) and related wafer-processing equipment, serving semiconductor wafer fabs globally. Its portfolio spans new SITEK-branded SRDs in 6", 8", and 12" wafer configurations (270/280/470/480/870/880/2300/4300/8300 series), refurbished units from discontinued legacy OEMs including Semitool, Rhetech, and Verteq, the proprietary SlickDevice retrofittable SRD controller, an extensive spare parts catalog covering SRDs, box washers, wet benches, and batch spray systems, and complementary equipment categories such as mask aligners, particle counters, profilometers, ellipsometers, etchers/strippers, and photoresist pumps.

The core technology is centered on wafer drying and wet-process equipment, with proprietary features including the SlickDevice plug-and-play controller that modernizes installed legacy SRDs, custom rotor inserts enabling multi-wafer-size compatibility within a single chamber, and video source inspections delivered pre-shipment for quality assurance. The company combines equipment manufacturing with deep aftermarket capabilities, including refurbishment to like-new condition, motor controller and brushless motor repair, rotor rebalancing, and expert on-site service at customer fabs.

The business model is sales-led and direct, with quote-based pricing across all products and services; there is no e-commerce checkout or public price list. Revenue streams include equipment sales (new and refurbished), spare parts, refurbishment services, repair services, and on-site field service, all sold to a single horizontal segment of semiconductor wafer fabs. SITEK maintains strategic support and distribution relationships with Semitool, Rhetech, Verteq, and Entegris/Fluoroware, positioning itself as the primary third-party provider for legacy and discontinued semiconductor wet-process equipment. Marketing is driven through a 400+ product website catalog, a technical blog, a YouTube channel with 10+ tutorial videos, and pre-shipment video source inspections, targeting fab engineers and operations buyers worldwide.

Direct peers

• AP&S International: Specializes in wet processing and cleaning equipment for the semiconductor industry, including single-wafer and batch wet benches. Directly comparable to Sitek in the wet-processing/cleaning equipment niche serving similar fab customers.
• RENA Technologies: Manufacturer of wet-chemical processing and cleaning equipment for semiconductor and related industries. Comparable to Sitek in targeting wet-process equipment for wafer fabs, though at a larger scale and broader product portfolio.
• Kaijo Corporation: Japanese manufacturer of semiconductor cleaning equipment including megasonic, single-wafer, and batch cleaning systems. Comparable to Sitek in the wafer-cleaning equipment niche, though focused on OEM new equipment rather than refurbishment.
• Modutek Corporation: Specializes in wet bench equipment and chemical process systems for semiconductor and solar manufacturing. Comparable niche player to Sitek focused on wet-processing equipment for wafer fabs and related industries.

Broad incumbents

• Tokyo Electron (TEL): One of the largest global semiconductor equipment manufacturers, with a broad portfolio including wet-clean/coater-developer systems. Overlaps with Sitek in wafer cleaning equipment but operates at vastly greater scale and across all advanced nodes.
• Lam Research: Major semiconductor equipment OEM with strong positions in etch, deposition, and wet clean. Comparable to Sitek in serving wafer fab cleaning and surface preparation needs, but at scale across leading-edge and mature nodes.
• Entegris: Major U.S. supplier of semiconductor materials, equipment (acquired Semitool/Fluoroware), and wafer-handling products. Directly comparable as both a strategic partner to Sitek (HTC box washer parts distribution) and a broad incumbent competitor in wafer cleaning and handling.
• SCREEN Holdings (SCREEN Semiconductor Solutions): Large Japanese semiconductor equipment manufacturer producing cleaning, coating, and wafer-processing systems. Overlaps with Sitek in wafer cleaning and surface preparation but operates globally with a much broader product portfolio across advanced nodes.

Emerging players

• TMC Industries: Supplier of semiconductor equipment parts, components, and refurbishment services. Comparable to Sitek's spare-parts and refurbishment business model serving fab maintenance needs, though at a smaller scale and broader parts catalog.
• Ultra T Equipment: Independent reseller and refurbisher of semiconductor manufacturing equipment, including cleaning and processing tools. Comparable to Sitek's refurbishment and resale business model targeting fabs seeking cost-effective alternatives to new OEM equipment.
