الدوائر المتكاملة ( Integrated Circuit )

قامت شركة تكساس إنسترومنتس الأمريكية باختراع الدوائر المتكاملة في عام 1958.

وكانت هذه الشركة قد أنتجت أول دائرة متكاملة أو رقامة سيليكونية ثم أصبحت الدوائر الإلكترونية تجمع على شرائح من السيليكون.

أولاً : يتم تكوين بلورات من السيليكون نوع من الكوارتز صناعياً وتقطع إلى شرائح رقيقة ويمكن صنع 500 دائرة متكاملة من كل هذه الشرائح.

ثانيا : يرسم مخطط الدائرة الإلكترونية الذي يتضمن القطع والعناصر المكونة للدائرة بمقياس رسم 1:250

ثم يصغر الرسم بما يتناسب مع حجم الرقاقة وطبعه على الشريحة بحيث يطبع على الشريحة الواحدة 500 دائرة متكاملة.

ثالثاً : توضع الشرائح في فرن حيث تعرض لمواد كيماوية مختلفة فتدخل ذرات المواد الكيماوية إلى الشرائح عبر خطوط الدوائر

وتعالج كل منطقة من الدائرة المتكاملة بشكل مختلف وذلك طبقا ً للوظيفة النهائية لها ومن ثم توصل هذه الأجزاء معاً بأسلاك رفيعة لتكوين دائرة إلكترونية كاملة.

رابعاً : تقطع الشرائح إلى رقائق بواسطة منشار من الماس أو مقص ليزر حيث توضع كل رقاقة في غلاف بلاستيكي.
