中国のパワーチップメーカーが値上げ、利益は黒字に転換 United Novaは黒字化し、MOSFET、IGBT、炭化ケイ素、アナログ製品で価格を15~25%引き上げ、生産能力も拡大している。Galaxy MicroelectronicsとBright Powerも大幅な増益を記録した。これは長い価格戦争の後に価格決定力が戻ってきたことを示し、セクター全体を押し上げる。
価格戦争から値上げへの本格的な転換は、このテーマの利益見通しを変える。

台湾積体電路製造(TSMC)は、次世代のA14プロセス技術について、量産開始をはるかに前にして顧客から強い関心を得ていると明らかにした。2026年第2四半期の決算説明会で経営陣が述べたもので、顧客によるテープアウトはすでに始まっており、予定を前倒しで進んでいる。A14はTSMCの第2世代ナノシートトランジスタ技術であり、2ナノメートル技術と比べて同じ電力で10~15%高い性能、または同じ速度で25~30%低い電力を実現し、チップ密度は約20%向上する設計となっている。TSMCによると、社内の製品に近い検証用チップはデバイス性能で90%近くを達成し、256メガビットSRAMは歩留まりが90%近くに達した。同社はA14が2027年に事前生産に入り、2028年に量産を迎えると見込んでいる。TSMCはまた、A14ファミリーの拡張としてA13とA12を発表した。A13は97%の光学縮小によりダイ面積を6%以上削減する設計で、A12はA14プラットフォームにスーパーパワーレール技術をもたらすと期待されており、いずれも2029年の量産が予定されている。別途、マイクロンは世界初となる512ギガバイトDDR5モジュールを複数のサーバープラットフォームで実証することに成功したと発表し、AMDとインテルがこのモジュールを積極的に検証している。オン・セミコンダクターは、シリコンウェハーそのものをパッケージの基盤として用いる拡張性の高いアーキテクチャ「Embedded Power Platform」を発表した。

Vicorは、特許取得済みの垂直電力供給技術について、大手AI機器メーカーに非独占的ライセンスを供与した。これにより同OEMは、Vicorと未ライセンスのサプライヤーの両方からVPDモジュールを調達できるようになる。この契約は、Vicorの短期的な重要触媒であるIPマネタイゼーションに影響を与える一方、ライセンス供与と権利行使の結果への依存を浮き彫りにしている。ライセンス供与の手法は、高性能AIプロセッサへの電力供給におけるラストインチ問題に対処するVicorの特許取得済みVPDアーキテクチャと相まって、ハイパースケーラーが電力供給サプライチェーンをどのように構築するかに大きく影響する可能性がある。Vicorの見通しでは、2029年までに売上高14億ドル、利益4億5380万ドルを計上し、公正価値3億8625万ドルは73%の上昇余地を示唆している。一方、最も強気なアナリストはすでに、2029年までに年間売上高成長率約48.7%と利益約4億8610万ドルを見込んでいた。同社がChiP Fab 2とFab 3を建設するためにMerrimackとHooksettで大規模用地を取得したことは、VPD契約と密接に関連している。米国内の製造拡大は、稼働率不足リスクと固定費圧力が依然として中心的な課題であるものの、モジュール需要とサプライチェーンの冗長性を支える可能性がある。
