    Abstract: PURPOSE: A MOS(Metal-Oxide-Semiconductor) controlled thyristor is provided to be capable of increasing the maximum controllable current of the MOS controlled thyristor and restraining the snap-back phenomenon of the MOS controlled thyristor by using a trench gate structure. CONSTITUTION: A MOS controlled thyristor is provided with a trench gate(203) for simultaneously forming a finger gate and a main gate by etching a plurality of trenches to the vertical direction of the trench gate before forming the trench gate and a P-type base(201) self-aligned by using the trench gate as a mask. At this time, the channel width of the main gate is increased through the trench gate. Preferably, a plurality of trenches are formed at the trench gate.

    Abstract translation: 目的:提供MOS(金属氧化物半导体)控制晶闸管,以便能够通过使用沟槽栅极结构来增加MOS控制晶闸管的最大可控电流并抑制MOS控制晶闸管的回跳现象。 本发明的MOS控制晶闸管具有沟槽栅极(203),用于在形成沟槽栅极和P型基极之前,通过在沟槽栅极的垂直方向上蚀刻多个沟槽来同时形成指栅极和主栅极 (201)通过使用沟槽栅作为掩模来自对准。 此时,主栅极的沟道宽度通过沟槽栅极增加。 优选地,在沟槽栅极处形成多个沟槽。
