摘要: A method of forming a tunnel-free tungsten plug is described. Semiconductor device structures are provided in and on a semiconductor substrate. An insulating layer of borophospho-tetraethoxysilane (BP-TEOS) is deposited overlying the semiconductor device structures. Contact openings are etched through the insulating layer to the underlying semiconductor device structures wherein a tunnel opens in the insulating layer between contact openings. The semiconductor substrate is covered with a first barrier metal layer. The semiconductor substrate is coated with a spin-on-glass layer wherein the contact openings and the tunnel are filled with the spin-on-glass. The spin-on-glass is anisotropically etched away whereby the spin-on-glass remains only within the tunnel. The semiconductor substrate is covered with a second barrier metal layer. The contact openings are filled with tungsten which is etched back to form tungsten plugs within the contact openings wherein the filled tunnel provides tunnel-free tungsten plugs in the fabrication of the integrated circuit device.

摘要: The present invention provides a structure and a method of forming a stepped trench oxide structure for a semiconductor memory device. The stepped trench oxide structure has "oxide steps" (e.g., 252 or 34A, 34B, 34C) in the gate oxide 20 surrounding the tunnel oxide layer 30. The oxide steps 34 are formed where the oxide thinning effect normally thins the tunnel oxide 30 around the perimeter of the tunnel oxide layer 30. The oxide steps 34 252 compensate for the oxide thinning effect and eliminate the problems associated with the oxide thinning effects. The oxide steps are preferably formed using one photo mask to form two different sized openings using different photoresist exposure times. The preferred method comprises forming a first tunneling opening 220A in a first (gate) oxide layer 220. Then, forming a second oxide layer 250 over said exposed substrate and said first oxide layer 220. A second opening 250A (smaller than the first opening) is formed in the second oxide layer thereby forming a first step 252. Next, a third oxide layer 270 is formed over said exposed substrate, the first oxide layer 220 and the second oxide layer 250 thereby propagating the first step 252. The oxide thinning edge effect is eliminated by the first step.

The fastening apparatus includes a collet and a sleeve. The collet has a bottom and a plurality of jutting plates. The collet is mounted onto the holding dock to hold the fastened member. The jutting plates are located longitudinally on the bottom in a protrusive manner. Each of the jutting plates has an outer surface on which a portion is extended outwards greater than other portion. The collet is encased in the sleeve. The sleeve has a tubular wall which has a plurality of segments corresponding to the jutting plates. Each segment has an inner surface on which a portion is extended inwards greater than other portion. When the greater extended inward portion of the tubular wall is in contact with the greater extended outwards portion of the jutting plate, the jutting plate is tilted inwards to press the fastened member.
