L'invention concerne une batterie à semi-conducteur comprenant une électrode positive, une électrode négative et un électrolyte à semi-conducteur. L'électrolyte à semi-conducteur contient des particules pour empêcher des courts-circuits de contact entre l'électrode positive et l'électrode négative. L'invention concerne également un procédé de fabrication et un appareil de fabrication d'une batterie à semi-conducteur. Dans une batterie à semi-conducteur de la présente invention, des particules sont disposées entre une électrode positive et une électrode négative pour séparer physiquement l'électrode positive et l'électrode négative, garantissant ainsi qu'aucun court-circuit de contact ne se produise entre l'électrode positive et l'électrode négative. Par conséquent, dans un procédé de fabrication d'un électrolyte à semi-conducteur, l'épaisseur de l'électrolyte à semi-conducteur peut être facilement contrôlée. Par conséquent, l'épaisseur de l'électrolyte à semi-conducteur peut être réduite sans provoquer de court-circuit de contact entre l'électrode positive et l'électrode négative.
