Morgan Stanley Is Bullish on Japan's AI Memory Demand Chain in the Semiconductor Production Equipment Sector

Overview

This is a monthly industry report on Japan's semiconductor production equipment sector published by Morgan Stanley on June 22, 2026. The report covers stock price performance, AI-driven memory demand, changes in DRAM and NAND demand, earnings updates and upward revisions for Tekscend Photomask, and the re-rating case for SCREEN Holdings.

Core views

The core view is that, compared with traditional chatbots, Agentic AI requires longer context, more iterations, and larger working memory, thereby reinforcing demand related to DRAM, NAND, KV Cache, RAG, and high-capacity storage. The report also points out that rapidly growing demand for HBM applications may drive outsourcing of non-HBM photomasks, benefiting commercial photomask makers; meanwhile, SCREEN Holdings has a basis for re-rating due to improved profitability in its SPE business.

Analysis framework

The report uses a combination of industry conditions, AI workloads, memory architecture, earnings forecasts, and relative operating metrics: it first discusses Agentic AI's demand for memory capacity and working memory, then extends the analysis to DRAM, NAND, HBM, and photomask outsourcing, and finally discusses Tekscend Photomask and SCREEN Holdings at the company level through forecast tables and operating margins.

Methodology notes

• Industry Rating FrameworkMorgan Stanley Industry View

  Attractive

  Attractive means that analysts expect the industry under coverage to be attractive relative to the relevant broad market benchmark over the next 12-18 months.

• Theme-Driven AnalysisAgentic AI Memory Demand Mapping

  Deriving memory and equipment demand from AI workloads

  The report maps Agentic AI's need for long context, multi-step loops, and persistent working memory to DRAM, NAND, Flash KV Cache, RAG vectors, and high-capacity storage.

• Corporate Earnings ForecastUpward Revisions and P&L Updates

  Tekscend Photomask earnings update

  The report discusses Tekscend Photomask through forecast tables and P&L projections, focusing on the impact of expanding outsourcing demand on earnings forecasts.

• Relative Operating ComparisonOperating Margin and Re-rating Analysis

  SCREEN Holdings re-rating opportunity

  The report emphasizes that SCREEN Holdings has not materially lagged front-end equipment peers in overall company operating margin, and that its SPE business has maintained an operating margin above 20% since F3/23.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Japan's Semiconductor Production Equipment Industry

  The core industry asset covered by the report

  Strengths

  The industry view is Attractive, supported by AI memory demand, advanced packaging, and the memory investment cycle.

  Weaknesses

  The industry is highly cyclical, and orders, capital expenditure, and memory prices may fluctuate.

  Comparison

  Relative to the broad market benchmark, the report assigns an attractive industry view for the next 12-18 months.

  Risks

  AI demand may disappoint, customer capex may slow, memory prices may decline, or valuations may have already priced in the upside.

• DRAM/NAND Memory Chain

  A key channel through which Agentic AI demand is transmitted

  Strengths

  Long context, multi-step loops, KV Cache, RAG, and high-capacity storage demand may increase memory capacity demand.

  Weaknesses

  The extracted text lacks complete pricing and supply-demand quantitative data, making it difficult to directly verify elasticity.

  Comparison

  Compared with traditional chatbots, Agentic AI is described as requiring larger working memory and more complex memory architecture.

  Risks

  The pace of AI application rollout, memory configuration per unit of compute, pricing cycles, and inventory changes may affect demand intensity.

• Tekscend Photomask

  The earnings update and upward revision target discussed in the report

  Strengths

  Growth in HBM applications may prompt major memory manufacturers to outsource lower-priority non-HBM photomask production to commercial photomask makers.

  Weaknesses

  The disclosure page shows that Morgan Stanley participated in or received compensation for investment banking business related to the company in the past 12 months, which requires attention to potential conflicts of interest.

  Comparison

  Its investment thesis is tied to HBM expansion and the trend of outsourcing non-HBM photomasks.

  Risks

  Outsourcing demand may expand less than expected, the customer in-house production ratio may change, pricing pressure may emerge, or investment banking relationships may create risks to research independence.

• SCREEN Holdings

  The re-rating stock emphasized in the report

  Strengths

  Profitability in the SPE business continues to improve, with operating margin remaining above 20% since F3/23.

  Weaknesses

  The extracted report text does not provide a complete valuation table or target price.

  Comparison

  The report says its overall company operating margin has not materially lagged front-end equipment peers.

  Risks

  A downturn in semiconductor equipment order cycles, margin compression, peer valuation de-rating, or failure of the re-rating thesis to materialize.

Key data

• Report Date2026-06-22The cover shows June 22, 2026 06:29 AM GMT.
• Industry ViewJapan Industry View AttractiveThe cover assigns an Attractive view to Japan's semiconductor production equipment industry.
• Rating Time Frame12-18 monthsThe disclosure page states that Morgan Stanley industry views and stock ratings generally correspond to the next 12-18 months.
• Agentic AI Loop Characteristics10s~100s loopsAn illustration in the main text indicates that Agentic AI loops require substantial working memory.
• SCREEN SPE Operating MarginAbove 20% since F3/23The main text states that SCREEN's SPE business has maintained an operating margin above 20% since F3/23.
• HBM-Related DemandRapid growthTable text indicates that demand for HBM applications is growing rapidly, and major memory manufacturers may increasingly outsource lower-priority non-HBM photomask production.

Impact & implications

If the report's thesis plays out, the expansion of AI servers and Agentic AI applications will benefit not only GPUs, but also DRAM, NAND, photomasks, and the semiconductor production equipment chain through demand for working memory, model weights, KV Cache, vector retrieval, and high-capacity storage. Related Japanese equipment and materials companies may benefit from industry tailwinds, upward earnings revisions, and valuation re-rating, though the conclusion still needs to be validated against subsequent orders, pricing, capacity utilization, and company disclosures.

Risks

• If Agentic AI-driven memory demand comes in below expectations, the incremental thesis for DRAM, NAND, and the equipment chain will weaken.
• Memory prices, customer capital expenditure, and semiconductor equipment orders are cyclical and may affect industry earnings and valuations.
• The outsourcing demand assumption for Tekscend Photomask depends on HBM growth and production allocation by major memory manufacturers, creating execution uncertainty.
• The re-rating of SCREEN Holdings depends on sustaining SPE business margins and market recognition; if earnings improvement slows, the re-rating may be hindered.
• Morgan Stanley discloses shareholding, investment banking, or other service relationships with multiple covered companies, and investors should treat the research as one input rather than the sole basis for decisions.
• The currently extracted text lacks visual recognition content for multiple charts, and some price, valuation, and forecast figures are not fully presented.

What to watch

• Whether Agentic AI applications continue to drive demand for long context, multi-step loops, and working memory.
• DRAM and NAND price trends, inventory levels, and capex plans of major memory manufacturers.
• Whether growth in HBM applications continues to drive outsourcing of non-HBM photomask production.
• Changes in Tekscend Photomask's subsequent earnings forecasts, orders, and customer outsourcing ratios.
• Whether SCREEN Holdings can continue to maintain SPE business operating margins above 20%.
• Whether Morgan Stanley adjusts its industry view, company ratings, or forecasts in subsequent monthly or company updates.
